Re connecting with Sero!, here is a repeat of a previous post:

Brought my attention by Brian Moon,  a knowledge design practitioner we have worked with.  I am a longtime proponent of concept mapping, we developed thousands.  Can this finally be a way to efficiently use such mapping to learn and analyze.?  Can it convert concept maps into knowledge maps, or at least their skeletal infrastructure?   Linking to process modeling?  Will be taking a deeper look:

Introducing Sero!, a concept mapping-based platform for learning and knowledge assessment.

We are harnessing the power of concept mapping to move well beyond outmoded assessments, exercising holistic and higher order thinking skills for formative and summative assessments. See what we're up to at https://www.serolearn.com. And take a sneak peek under the hood on our Assessor and Taker instructional pages.  ....

Write for the Future – if you can get away with it

1 Comment

The title of my previous post, Software Development: the Secret of Success, was originally meant to be tongue in cheek, as you might have guessed. Like that of another post, The Secret  of Academic Success. It was a play on that title.

Then I got ambitious and tried to find a secret but the best I could come up with was “get help … “; which is a lame and obvious platitude. But at the last moment, at the end of the post, I had a revelation: “write for the future” or, more generally, “build for the future”.

OK, sounds like another lame and obvious platitude. But hear me out.

It’s a platitude because who would disagree that it’s good to write for the future? But on the surface it’s not practical advice for at least two reasons:

One, how do we know what the future holds? If we don’t know what’s coming, how can we write for it?

Two, it’s going to take extra time/effort/resources/money which we may not have. We may have a boss who wants something now and doesn’t give a toss for the future.

Nevertheless I still think it’s good advice. Sometimes rules that are on the surface obviously wrong are true at a deeper level. Marshall McLuhan has many such sayings. One example is, “the effect precedes the cause”. I think a lot about that one.

A hard earned lesson

The need to write for the future was brought home by direct experience with research software I used, as I briefly explained in the previous blog post. At one point we had a wonderful Lucid interpreter, written originally (in C) by C. Ostrum and majorly upgraded by A. Faustini. It had excellent syntactic and runtime error checking; integers, reals, atoms, strings, lists; user defined functions; interactive I/O; and an escape to UNIX. It ran all the programs in the 1985 book plus powerful array (field) capabilities.

Now that interest in dataflow and Lucid is picking up I would love to make it available. I have the source. But nobody can run Lucid on it because the source won’t compile. Putting it through a modern C compiler produces literally hundreds of errors and warnings. Apparently 30 years ago C compilers were much more tolerant.

The pLucid interpreter (that’s what we’re talking about) was not, on the whole, written for the future. I take a lot of the blame for that. I kept asking for more features now, instead of (say) insisting that the code go through lint without any reports. I was the boss who didn’t give a toss.

You can say in my defense, how was I to anticipate that I’d need to compile it three decades in the future? Well I had many reasons to anticipate this.

Y2K syndrome

Anyone with any experience in software should realize that even professionals seriously and regularly underestimate the length of time that a program is going to be around, and the challenges it is going to face.

The canonical example is Y2K. The programs affected were mostly written in the 50s and 60s when the programmers couldn’t imagine that three or four decades later they’d still be running. It seemed wasteful of resources at the time to include “19” in year. (In fact much less was at stake. They could have used one bit to distinguish 19.. and 20.. years and had software that worked thru 2099).

I concede that in some ways the pLucid interpreter was written for the future. For a start it was written in C and C did not go away – though many thought it would be replaced by something more high level. And it ran under UNIX on a terminal. Terminals were overshadowed by GUIs but they didn’t disappear.

Patience, patience

The experience with the popshop code was the other end of the spectrum. It was what people call “overengineered”. It was highly modular (dozens of informal C modules). Most of the routines were tiny, maybe half a dozen lines of code. Commented code. There were several layers of abstraction, strictly obeyed (C has no facilities for enforcing abstraction, this was programmer discipline).

Each module was a folder with several files. These included a file of procedures, a list of other modules needed (“imports”), a file of global declarations, a file of initialization code, etc. A special too we produced, called sloth, integrated the modules, called in the imports in logical order etc and produced a huge .c file. The total software effort was far more than that involved in producing a straightforward interpreter. The idea was to make it easy to generate intensional software – like an intensional  spreadsheet.

(Sloth suffered from a particularly egregious example of present-oriented programming. Obviously I kept the source for sloth. But to save a few lousy bytes, I compressed it into .C format. And now only a couple of decades later, I discover that the decompressing routines are no longer available. Gone. Lost.)

By the measure, “I want something now” it was a failure. No useful application was ever produced, just test versions. It was almost completed but I abandoned in when I realized I’d never solve the memory management problem. C has no garbage collector and I would never have tracked down the last memory leak.

That was a mistake, and an example of not writing for the future. I should have realized that memory would become plentiful and even leaky programs would be useful up to a point. I should have realized that eventually something like C would appear with automatic memory management.

The future is bright

I made a similar programming-for-the-present error many many years ago with my attempts to implement my ‘Griff’ macro processor. I dithered between doing it in 7040 assembler, FORTRAN IV, and LISP (the only practical choices at the time).

7040 assembler was too difficult (and would have been a dead end). LISP was too slow and FORTRAN IV would probably have been slow, plus difficult. So I abandoned Griff.

Big mistake. Either the FORTRAN or the LISP options would have soon given me a usable interpreter, once the hardware and software caught up. FORTRAN would have been trickier but more portable.

For a long time I attributed the failure of the popshop to the classic mistake of overengineering, and that  of Griff to underpowered hardware. In fact if I’d had the outlook of writing for the future I would have finished them both and soon reaped the benefits.

In both cases I was a bit ahead of my time. But that doesn’t have to be fatal. You have to write for the future and – as the French say – give time time.

It was the popshop that really came through in  the end. Eventually Python arrived and I discovered I could basically transcribe the popshop software to Python. All the hard work had been done – for example, presenting Lucid expression as an abstract data type.

How do you write for the future?

While it’s true that we can’t predict the future, by now we know a lot about the future of IT and this knowledge can be used as a guide for writing (or more generally building) for the future.

For a start we know that hardware is soon going to be significantly more powerful. Processor speeds may not increase by much but machines will have more cores and GPUs will play a bigger role. Memory will be bigger and faster as will disk speeds and capacities. And advances in compiler technology will produce clever code from straight forward programs.

As a result software performance will improve dramatically without the need for complicated rewrites. Rod Burstall once said that “efficiency is the enemy of clarity”. So one  form of writing for the future is to write relatively simple if suboptimal algorithms and let future hardware and compiler improvements take care of performance issues.

(I  wish someone had made this point when I was working on Griff so many years ago.)

On the other side of the coin we can be almost certain that our software will eventually have to support far greater volumes of data, of queries, of transactions and the like than we currently experience. One example is the unemployment application processing systems in New York that because of  Corona virus shutdowns had to process  hundreds of thousands of applications – they failed under the load.

In this case writing for the future means producing software that can quickly be scaled up – by orders of magnitude if necessary. Again this is favored by simple algorithms and data structures

Immortal software

Another trend we can take for granted is that the software we produce will be in use much longer than we can imagine, in spite of our current plans. The New York software also suffered here – it was written decades ago in COBOL. Years of austerity ruled out upgrades.

Once we are realistic about how long our software is going to be used, we see several future-proofing strategies.

For one, documentation is very important. Imagine the situation of some software engineer maintaining a program that was written before she was born, in a language neither she or any of her colleagues has ever learned. Without documentation she is lost.

The same can be said for basic practices such as having meaningful identifier names and naming schemes that tell you something about what the variable denotes; such as “getTemperature” and “setTemperature”.

It’s clearly important to carefully choose the language and system. All else being equal it should be a language that’s been around and will stay around, and it should be a very stable release. This rules out, for example, Python 2 and the absolute latest version of Python 3.

A pattern emerges

In this way we could continue listing known trends we have to take into account and fairly obvious strategies to deal with them. For example we can be confident that errors will be found and extra features will be requested. This calls for documentation, again, and general purpose (as opposed to very specific) code.

However a  pattern emerges, that almost every practice (say, information hiding and abstraction) that is considered Good Software Engineering is future oriented. So isn’t “writing for the future” just being a good software engineer?

Unfortunately not. There are a whole set of practices that are vital but not future oriented. They all have the goal of gaining a temporary advantage. And these practices may violate Good engineering principles.

An example, given above, is to write a complex but efficient algorithm to solve a critical performance issue. This gives the software an advantage, but one that is  temporary in the sense that hardware advances make the complex solution eventually unnecessary.

Another example is skipping the documentation stage in the rush to get to market. This may save a lot of time (and is very common) but down the road the lack of documentation can become a serious, and  permanent, disadvantage.

A judgement issue

So in summary, people who produce software have to manage a contradiction between doing things that are good in the short term, and using Good practices that benefit the long term. When I propose “write for the future” I don’t mean it as an absolute – I don’t mean always choose the long term good. Any software project (especially if a business is based on it) will need short term advantages.

What I mean by “write for the future” is that this should be the default choice. Write for the present – for an immediate advantage – only if the advantage is 1) real and 2) really needed. I don’t believe there is any fixed, more precise rule that makes this choice. It’s always a judgement call that depends on the context.

In general if the software is not entangled in the market – not, for example, an implementation of a key feature of a system being sold – then it’s much easier to choose the future. This includes research software, open source systems, and personal side projects.

But where economic competition is involved, the pressure for short term advantage can be irresistible. I believe this explains why, after decades of research in software engineering, so much commercial software is so unreliable.

Build for the future

It should be clear that the choose the future principle applies to domains other than software. The general preferred engineering approach is to build for the future.

There are several examples of spectacularly successful projects that owe their spectacular success to future-oriented engineering. Two examples come to mind: the internet and the personal computer.

The internet was designed and built as a general purpose highly resilient communication network long before the web let alone email were conceived. It has stood up to wave after wave of communication-heavy applications and even the Corona pandemic didn’t shut it down.

Personal computers preceded the internet but were almost perfectly suited to being nodes in a packet switching network. The basic reason is that it was a general purpose device designed when people wanted word processing and storing recipes.

In fact there is a theme running through these and other future-oriented successes: redundancy. For example, making a tool general purpose is itself already a form of redundancy – of devoting more than the bare minimum of resources to solve a problem.

Other examples come to mind: in education, teach for the future; in health, treat for the future; in athletics, train for the future.

I eat my own dog food. In this essay I anticipate objections and counter them before they’re raised. In fact this is an example of an effect preceding a cause: the effect is my counter argument, the cause is the objection.

Which brings us back to McLuhan. He was an expert at writing for the future. His “global village” and “medium is the message” concepts preceded the web by almost three decades. In fact McLuhan’s ideas are an outstanding example of an effect long preceding the cause.

So also is the whole idea of writing for the future. The cause is software disasters down the road. The effect is writing now to avoid them.

Usability Testing for Voice Content

1 Share

It’s an important time to be in voice design. Many of us are turning to voice assistants in these times, whether for comfort, recreation, or staying informed. As the interest in interfaces driven by voice continues to reach new heights around the world, so too will users’ expectations and the best practices that guide their design.

Voice interfaces (also known as voice user interfaces or VUIs) have been reinventing how we approach, evaluate, and interact with user interfaces. The impact of conscious efforts to reduce close contact between people will continue to increase users’ expectations for the availability of a voice component on all devices, whether that entails a microphone icon indicating voice-enabled search or a full-fledged voice assistant waiting patiently in the wings for an invocation.

But voice interfaces present inherent challenges and surprises. In this relatively new realm of design, the intrinsic twists and turns in spoken language can make things difficult for even the most carefully considered voice interfaces. After all, spoken language is littered with fillers (in the linguistic sense of utterances like hmm and um), hesitations and pauses, and other interruptions and speech disfluencies that present puzzling problems for designers and implementers alike.

Once you’ve built a voice interface that introduces information or permits transactions in a rich way for spoken language users, the easy part is done. Nonetheless, voice interfaces also surface unique challenges when it comes to usability testing and robust evaluation of your end result. But there are advantages, too, especially when it comes to accessibility and cross-channel content strategy. The fact that voice-driven content lies on the opposite extreme of the spectrum from the traditional website confers it an additional benefit: it’s an effective way to analyze and stress-test just how channel-agnostic your content truly is.

The quandary of voice usability

Several years ago, I led a talented team at Acquia Labs to design and build a voice interface for Digital Services Georgia called Ask GeorgiaGov, which allowed citizens of the state of Georgia to access content about key civic tasks, like registering to vote, renewing a driver’s license, and filing complaints against businesses. Based on copy drawn directly from the frequently asked questions section of the Georgia.gov website, it was the first Amazon Alexa interface integrated with the Drupal content management system ever built for public consumption. Built by my former colleague Chris Hamper, it also offered a host of impressive features, like allowing users to request the phone number of individual government agencies for each query on a topic.

Designing and building web experiences for the public sector is a uniquely challenging endeavor due to requirements surrounding accessibility and frequent budgetary challenges. Out of necessity, governments need to be exacting and methodical not only in how they engage their citizens and spend money on projects but also how they incorporate new technologies into the mix. For most government entities, voice is a completely different world, with many potential pitfalls.

At the outset of the project, the Digital Services Georgia team, led by Nikhil Deshpande, expressed their most important need: a single content model across all their content irrespective of delivery channel, as they only had resources to maintain a single rendition of each content item. Despite this editorial challenge, Georgia saw Alexa as an exciting opportunity to open new doors to accessible solutions for differently abled citizens. And finally, because there were relatively few examples of voice usability testing at the time, we knew we would have to learn on the fly and experiment to find the right solution.

Eventually, we discovered that all the traditional approaches to usability testing that we’d executed for other projects were ill-suited to the unique problems of voice usability. And this was only the beginning of our problems.

How voice interfaces improve accessibility outcomes

Any discussion of voice usability must consider some of the most experienced voice interface users: people who use assistive devices. After all, accessibility has long been a bastion of web experiences, but it has only recently become a focus of those implementing voice interfaces. In a world where refreshable Braille displays and screen readers prize the rendering of web-based content into synthesized speech above all, the voice interface seems like an anomaly. But in fact, the exciting potential of Amazon Alexa for differently abled citizens represented one of the primary motivations for Georgia’s interest in making their content available through a voice assistant.

Questions surrounding accessibility with voice have surfaced in recent years due to the perceived user experience benefits that voice interfaces can offer over more established assistive devices. Because screen readers make no exceptions when they recite the contents of a page, they can occasionally present superfluous information and force the user to wait longer than they’re willing. In addition, with an effective content schema, it can often be the case that voice interfaces facilitate pointed interactions with content at a more granular level than the page itself.

Though it can be difficult to convince even the most forward-looking clients of accessibility’s value, Georgia has been not only a trailblazer but also a committed proponent of content accessibility beyond the web. The state was among the first jurisdictions to offer a text-to-speech (TTS) phone hotline that read web pages aloud. After all, state governments must serve all citizens equally—no ifs, ands, or buts. And while these are still early days, I can see voice assistants becoming new conduits, and perhaps more efficient channels, by which differently abled users can access the content they need.

Managing content destined for discrete channels

Whereas voice can improve accessibility of content, it’s seldom the case that web and voice are the only channels through which we must expose information. For this reason, one piece of advice I often give to content strategists and architects at organizations interested in pursuing voice-driven content is to never think of voice content in isolation. Siloing it is the same misguided approach that has led to mobile applications and other discrete experiences delivering orphaned or outdated content to a user expecting that all content on the website should be up-to-date and accessible through other channels as well.

After all, we’ve trained ourselves for many years to think of content in the web-only context rather than across channels. Our closely held assumptions about links, file downloads, images, and other web-based marginalia and miscellany are all aspects of web content that translate poorly to the conversational context—and particularly the voice context. Increasingly, we all need to concern ourselves with an omnichannel content strategy that straddles all those channels in existence today and others that will doubtlessly surface over the horizon.

With the advantages of structured content in Drupal 7, Georgia.gov already had a content model amenable to interlocution in the form of frequently asked questions (FAQs). While question-and-answer formats are convenient for voice assistants because queries for content tend to come in the form of questions, the returned responses likewise need to be as voice-optimized as possible.

For Georgia.gov, the need to preserve a single rendition of all content across all channels led us to perform a conversational content audit, in which we read aloud all of the FAQ pages, putting ourselves in the shoes of a voice user, and identified key differences between how a user would interpret the written form and how they would parse the spoken form of that same content. After some discussion with the editorial team at Georgia, we opted to limit calls to action (e.g., “Read more”), links lacking clear context in surrounding text, and other situations confusing to voice users who cannot visualize the content they are listening to.

Here’s a table containing examples of how we converted certain text on FAQ pages to counterparts more appropriate for voice. Reading each sentence aloud, one by one, helped us identify cases where users might scratch their heads and say “Huh?” in a voice context.

In areas like content strategy and content governance, content audits have long been key to understanding the full picture of your content, but it doesn’t end there. Successful content audits can run the gamut from automated checks for orphaned content or overly wordy articles to more qualitative analyses of how content adheres to a specific brand voice or certain design standards. For a content strategy truly prepared for channels both here and still to come, a holistic understanding of how users will interact with your content in a variety of situations is a baseline requirement today.

Other conversational interfaces have it easier

Spoken language is inherently hard. Even the most gifted orators can have trouble with it. It’s littered with mistakes, starts and stops, interruptions, hesitations, and a vertiginous range of other uniquely human transgressions. The written word, because it’s committed instantly to a mostly permanent record, is tame, staid, and carefully considered in comparison.

When we talk about conversational interfaces, we need to draw a clear distinction between the range of user experiences that traffic in written language rather than spoken language. As we know from the relative solidity of written language and literature versus the comparative transience of spoken language and oral traditions, in many ways the two couldn’t be more different from one another. The implications for designers are significant because spoken language, from the user’s perspective, lacks a graphical equivalent to which those scratching their head can readily refer. We’re dealing with the spoken word and aural affordances, not pixels, written help text, or visual affordances.

Why written conversational interfaces are easier to evaluate

One of the privileges that chatbots and textbots enjoy over voice interfaces is the fact that by design, they can’t hide the previous steps users have taken. Any conversational interface user working in the written medium has access to their previous history of interactions, which can stretch back days, weeks, or months: the so-called backscroll. A flight passenger communicating with an airline through Facebook Messenger, for example, knows that they can merely scroll up in the chat history to confirm that they’ve already provided the company with their e-ticket number or frequent flyer account information.

This has outsize implications for information architecture and conversational wayfinding. Since chatbot users can consult their own written record, it’s much harder for things to go completely awry when they make a move they didn’t intend. Recollection is much more difficult when you have to remember what you said a few minutes ago off the top of your head rather than scrolling up to the information you provided a few hours or weeks ago. An effective chatbot interface may, for example, enable a user to jump back to a much earlier, specific place in a conversation’s history.An effective chatbot interface may, for example, enable a user to jump back to a much earlier, specific place in a conversation’s history. Voice interfaces that live perpetually in the moment have no such luxury.

Eye tracking only works for visual components

In many cases, those who work with chatbots and messaging bots (especially those leveraging text messages or other messaging services like Facebook Messenger, Slack, or WhatsApp) have the unique privilege of benefiting from a visual component. Some conversational interfaces now insert other elements into the conversational flow between a machine and a person, such as embedded conversational forms (like SPACE10’s Conversational Form) that allow users to enter rich input or select from a range of possible responses.

The success of eye tracking in more traditional usability testing scenarios highlights its appropriateness for visual interfaces such as websites, mobile applications, and others. However, from the standpoint of evaluating voice interfaces that are entirely aural, eye tracking serves only the limited (but still interesting from a research perspective) purpose of assessing where the test subject is looking while speaking with an invisible interlocutor—not whether they are able to use the interface successfully. Indeed, eye tracking is only a viable option for voice interfaces that have some visual component, like the Amazon Echo Show.

Think-aloud and concurrent probing interrupt the conversational flow

A well-worn approach for usability testing is think-aloud, which allows for users working with interfaces to present their frequently qualitative impressions of interfaces verbally while interacting with the user experience in question. Paired with eye tracking, think-aloud adds considerable dimension to a usability test for visual interfaces such as websites and web applications, as well as other visually or physically oriented devices.

Another is concurrent probing (CP). Probing involves the use of questions to gather insights about the interface from users, and Usability.gov describes two types: concurrent, in which the researcher asks questions during interactions, and retrospective, in which questions only come once the interaction is complete.

Conversational interfaces that utilize written language rather than spoken language can still be well-suited to think-aloud and concurrent probing approaches, especially for the components in the interface that require manual input, like conversational forms and other traditional UI elements interspersed throughout the conversation itself.

But for voice interfaces, think-aloud and concurrent probing are highly questionable approaches and can catalyze a variety of unintended consequences, including accidental invocations of trigger words (such as Alexa mishearing “selected” as “Alexa”) and introduction of bad data (such as speech transcription registering both the voice interface and test subject). After all, in a hypothetical think-aloud or CP test of a voice interface, the user would be responsible for conversing with the chatbot while simultaneously offering up their impressions to the evaluator overseeing the test.

Voice usability tests with retrospective probing

Retrospective probing (RP), a lesser-known approach for usability testing, is seldom seen in web usability testing due to its chief weakness: the fact that we have awful memories and rarely remember what occurred mere moments earlier with anything that approaches total accuracy. (This might explain why the backscroll has joined the pantheon of rigid recordkeeping currently occupied by cuneiform, the printing press, and other means of concretizing information.)

For users of voice assistants lacking scrollable chat histories, retrospective probing introduces the potential for subjects to include false recollections in their assessments or to misinterpret the conclusion of their conversations. That said, retrospective probing permits the participant to take some time to form their impressions of an interface rather than dole out incremental tidbits in a stream of consciousness, as would more likely occur in concurrent probing.

What makes voice usability tests unique

Voice usability tests have several unique characteristics that distinguish them from web usability tests or other conversational usability tests, but some of the same principles unify both visual interfaces and their aural counterparts. As always, “test early, test often” is a mantra that applies here, as the earlier you can begin testing, the more robust your results will be. Having an individual to administer a test and another to transcribe results or watch for signs of trouble is also an effective best practice in settings beyond just voice usability.

Interference from poor soundproofing or external disruptions can derail a voice usability test even before it begins. Many large organizations will have soundproof rooms or recording studios available for voice usability researchers. For the vast majority of others, a mostly silent room will suffice, though absolute silence is optimal. In addition, many subjects, even those well-versed in web usability tests, may be unaccustomed to voice usability tests in which long periods of silence are the norm to establish a baseline for data.

How we used retrospective probing to test Ask GeorgiaGov

For Ask GeorgiaGov, we used the retrospective probing approach almost exclusively to gather a range of insights about how our users were interacting with voice-driven content. We endeavored to evaluate interactions with the interface early and diachronically. In the process, we asked each of our subjects to complete two distinct tasks that would require them to traverse the entirety of the interface by asking questions (conducting a search), drilling down into further questions, and requesting the phone number for a related agency. Though this would be a significant ask of any user working with a visual interface, the unidirectional focus of voice interface flows, by contrast, reduced the likelihood of lengthy accidental detours.

Here are a couple of example scenarios:

You have a business license in Georgia, but you’re not sure if you have to register on an annual basis. Talk with Alexa to find out the information you need. At the end, ask for a phone number for more information.

You’ve just moved to Georgia and you know you need to transfer your driver’s license, but you’re not sure what to do. Talk with Alexa to find out the information you need. At the end, ask for a phone number for more information.

We also peppered users with questions after the test concluded to learn about their impressions through retrospective probing:

  • “On a scale of 1–5, based on the scenario, was the information you received helpful? Why or why not?”
  • “On a scale of 1–5, based on the scenario, was the content presented clear and easy to follow? Why or why not?”
  • “What’s the answer to the question that you were tasked with asking?”

Because state governments also routinely deal with citizen questions having to do with potentially traumatic issues such as divorce and sexual harassment, we also offered the choice for participants to opt out of certain categories of tasks.

While this testing procedure yielded compelling results that indicated our voice interface was performing at the level it needed to despite its experimental nature, we also ran into considerable challenges during the usability testing process. Restoring Amazon Alexa to its initial state and troubleshooting issues on the fly proved difficult during the initial stages of the implementation, when bugs were still common.

In the end, we found that many of the same lessons that apply to more storied examples of usability testing were also relevant to Ask GeorgiaGov: the importance of testing early and testing often, the need for faithful yet efficient transcription, and the surprising staying power of bugs when integrating disparate technologies. Despite Ask GeorgiaGov’s many similarities to other interface implementations in terms of technical debt and the role of usability testing, we were overjoyed to hear from real Georgians whose engagement with their state government could not be more different from before.


Many of us may be building interfaces for voice content to experiment with newfangled channels, or to build for differently-abled people and people newer to the web. Now, they are necessities for many others, especially as social distancing practices continue to take hold worldwide. Nonetheless, it’s crucial to keep in mind that voice should be only one component of a channel-agnostic strategy equipped for content ripped away from its usual contexts. Building usable voice-driven content experiences can teach us a great deal about how we should envisage our milieu of content and its future in the first place.

Gone are the days when we could write a page in HTML and call it a day; content now needs to be rendered through synthesized speech, augmented reality overlays, digital signage, and other environments where users will never even touch a personal computer. By focusing on structured content first and foremost with an eye toward moving past our web-based biases in developing our content for voice and others, we can better ensure the effectiveness of our content on any device and in any form factor.

Eight months after we finished building Ask GeorgiaGov in 2017, we conducted a retrospective to inspect the logs amassed over the past year. The results were striking. Vehicle registration, driver’s licenses, and the state sales tax comprised the most commonly searched topics. 79.2% of all interactions were successful, an achievement for one of the first content-driven Alexa skills in production, and 71.2% of all interactions led to the issuance of a phone number that users could call for further information.

But deep in the logs we implemented for the Georgia team’s convenience, we found a number of perplexing 404 Not Found errors related to a search term that kept being recorded over and over again as “Lawson’s.” After some digging and consulting the native Georgians in the room, we discovered that one of our dear users with a particularly strong drawl was repeatedly pronouncing “license” in her native dialect to no avail.

As this anecdote highlights, just as no user experience can be truly perfect for everyone, voice content is an environment where imperfections can highlight considerations we missed in developing cross-channel content. And just as we have much to learn when it comes to the new shapes content can take as it jumps off the screen and out the window, it seems our voice interfaces still have a ways to go before they take over the world too.

Special thanks to Nikhil Deshpande for his feedback during the writing process.
