ChatGPT was launched simply over a 12 months in the past (on the finish of November 2022), and numerous folks have already written about their experiences utilizing it in all kinds of settings. (I even contributed my very own sizzling take final 12 months with my O’Reilly Radar article Actual-Actual-World Programming with ChatGPT.) What extra is left to say by now? Effectively, I guess only a few of these folks have really chatted with ChatGPT. And by “chat” I imply the unique sense of the phrase—to carry a back-and-forth verbal dialog with it similar to how you’ll chat with a fellow human being. I just lately chatted with ChatGPT, and I wish to use that have to mirror on the usability of voice interfaces for AI instruments based mostly on Massive Language Fashions. I’m personally on this matter since I’m a professor who researches human-computer interplay, consumer expertise design, and cognitive science, so AI voice interfaces are fascinating to me.
Right here’s what I did: In December 2023 I put in the official ChatGPT iOS app from OpenAI on my iPhone and used its voice enter mode to carry a number of hour-long conversations with it whereas driving long-distance on California highways. I wore normal Apple earbuds with a built-in mic and talked with ChatGPT similar to how I’d be speaking to somebody on the telephone whereas driving. These lengthy solo drives have been the proper alternative to check out ChatGPT’s voice characteristic as a result of I couldn’t work together with the app utilizing my fingers for security causes.

Be taught sooner. Dig deeper. See farther.
I had a really clear use case in thoughts: I needed a dialog accomplice to maintain me awake and alert whereas driving long-distance on my own. I’ve discovered that listening to music or podcasts doesn’t hold me alert once I’m drained as a result of it’s such a passive expertise—however what does hold me awake is having somebody to speak to, both within the automobile or remotely on the telephone. Might ChatGPT substitute a human dialog accomplice on this function?
The Good: ChatGPT Made Customized Podcasts to Preserve Me Engaged Whereas Driving
To not bury the lede, it seems that it did a outstanding job! As I used to be driving I used to be in a position to interact in a number of hour-long conversations with ChatGPT that ended solely as a result of I needed to take a relaxation cease or hit the utilization restrict for GPT-4. (I pay for a ChatGPT Plus subscription so I can use essentially the most superior GPT-4 mannequin, however that comes with a utilization restrict that I often hit after about an hour.)
One of the simplest ways to explain my expertise is (borrowing a beautiful time period my good friend coined) that it felt like listening to a personalised podcast. Since ChatGPT did many of the speaking, it was a largely passive listening expertise on my half aside from occasions once I needed to ask follow-up questions or direct it to vary subjects. Critically, this meant I might nonetheless focus most of my consideration on driving safely with a stage of distraction on par with listening to a podcast. Nevertheless it stored me extra alert than a daily podcast since I might actively direct the move of the dialog.
For a concrete instance of what such a personalised podcast felt like, I began one dialog by straight-up asking ChatGPT to maintain me awake whereas I used to be driving in Southern California from Los Angeles to San Diego. So it began by making small discuss street journeys basically and asking me about numerous California landmarks that I’ve visited, culminating in asking me extra about San Diego (the place I reside). When it requested me what locations I favored visiting essentially the most right here, I discussed the San Diego Zoo and it began telling me a bit about what makes this specific zoo notable. It talked about the idea of “naturalistic enclosures”—a time period I had not heard earlier than—so I requested it to elaborate on what this meant. ChatGPT’s rationalization of this idea bought me within the historical past of zoos, particularly the development from protecting animals in cages to in the present day’s cageless naturalistic enclosures, which goal to be higher for animal welfare. Throughout that section it talked about the time period “menagerie” in passing, which I had not heard of in that context earlier than, so I requested it to elaborate extra. It then went again farther in historical past to explain how a menagerie refers back to the phenomenon of historic rulers protecting unique animals for show with out as a lot regard for the animals’ well-being. Listening to that made me understand that I had really heard the time period menagerie in reference to a Star Trek episode of some type, however I forgot which one, so I requested ChatGPT to jog my reminiscence. It seems that “The Menagerie” was a really well-known episode of the unique Star Trek tv sequence, so after chatting about that episode and different well-known Star Trek episodes for a bit, we bought onto the subject of why that present was canceled after solely three seasons however later discovered a a lot bigger viewers in syndication (i.e., reruns). That in flip bought me curious concerning the idea of syndication within the tv enterprise, so ChatGPT dived extra into this matter. A couple of extra conversational twists and turns later, then I out of the blue realized that the hour had flown by and it was time to tug over for a loo break. Success!
Now, I don’t anticipate you to care in any respect concerning the particulars of the dialog I simply described because it wasn’t your dialog—it was mine! However I actually cared about it on the time since I used to be genuinely curious to study extra concerning the subjects that ChatGPT talked about, typically offhand within the midst of telling me about one thing else. It felt a bit like diving down a Wikipedia rabbit gap of following associated hyperlinks, the place every follow-up query I requested led it down one other meandering path. It was excellent for protecting me from becoming bored and sleepy throughout my lengthy drive.
ChatGPT isn’t simply good at this kind of superficial “personalised podcast about Wikipedia-level trivia” … it might additionally interact me in a extra substantive dialog a few activity I really wanted assist with in the mean time. In one other hour-long automobile chat, I prompted ChatGPT to assist me design a way to arrange my large assortment of just about 30 years’ price of non-public and work-related information for backup. I’ve been diligent about knowledge backup all through my life, however my information are fragmented amongst completely different media through the years—burning CDs and DVDs again within the day, a number of generations of exterior exhausting drives (which might be in numerous states of decay), college servers, Dropbox, and different cloud companies. For years I had an aspirational aim of unifying all of my backups into one central listing tree, akin to the idea of a monorepo in software program growth. I’ve just lately been brainstorming concepts for methods to design such a system and methods to cope with the sensible challenges of scaling and upkeep. So I figured that ChatGPT might assist me brainstorm throughout considered one of my lengthy drives. Once more it did an excellent job at participating me on this bespoke dialog, and the hour flew by earlier than I needed to take a relaxation cease. I gained’t bore you with particulars of what we mentioned, but it surely felt like speaking with an skilled in knowledge administration who was giving me recommendation about methods to cope with my specific problem.
Intermission: Why It Feels Form of Magical
Skeptical readers could also be considering at this level, “What’s the massive deal, it’s simply ChatGPT below the hood. I can already do all this from my pc by typing into the ChatGPT textual content field!” Though that’s technically true, there’s one thing magical about with the ability to do that all hands-free by way of voice. When you don’t consider me, simply strive it for an hour. My people concept is that talking and listening are hardwired into our mind’s innate language circuitry, however writing and studying are realized abilities (i.e., “software program” relatively than “{hardware}” in our brains). And that’s why it feels extra magical to carry a verbal dialog with an AI versus having the very same dialog in a textual content field on a display. If the AI is sweet sufficient, then it nearly feels such as you’re speaking to an actual particular person … at sure occasions once I was getting deep right into a back-and-forth dialog I practically forgot I used to be speaking to a machine. Nonetheless, that phantasm broke in a number of methods …
The Not-So-Good: Usability Limitations of the ChatGPT Voice Interface
Regardless of my constructive experiences with ChatGPT’s voice mode, it nonetheless didn’t reside as much as the gold normal of feeling like I used to be speaking with a fellow human being. That’s okay, although, since that is an extremely excessive bar! Listed below are a few of the methods it fell brief.
Should communicate whole request abruptly: Most notably, it felt unnatural to have to talk my whole request abruptly with out pausing. At any time when I paused for too lengthy, ChatGPT would interpret what I stated as far as my request and begin processing it. As an analogy, when typing a request in a textual content chat, you possibly can hit the Enter or Ship buttons … think about how bizarre it could be if ChatGPT began answering you the very second you stopped typing for one second! Observe that in human conversations, particularly face-to-face, we use visible cues to inform whether or not our dialog accomplice is completed speaking or whether or not they’re pausing a bit to consider the following factor to say. Even over the telephone, we will inform by vocal inflections whether or not they’re briefly paused and wish to hold speaking, or whether or not they’re accomplished with their flip and prepared for us to reply. Since ChatGPT can’t do any of that (but!) I typically needed to suppose exhausting about what I needed to say after which say it abruptly with out pausing. This was advantageous for easy requests like “Inform me extra about naturalistic enclosures in zoos,” however for extra complicated requests like describing some aspect of my knowledge backup setup, it was painful to must blurt out as a lot as I might with out pausing. Much more annoyingly, I’d typically make errors when speaking a lot abruptly with out pausing. Ideally the app would do a greater job at detecting pauses in human speech, taking each context and vocal intonations into consideration. A neater hack could be to have a voice command like “DONE” or “OVER” (like when folks use walkie-talkies) to sign that I’m accomplished speaking; nevertheless, this could additionally really feel unnatural for informal customers.Unpredictable wait occasions: Wait occasions (latency) for ChatGPT’s responses are unpredictable, and there aren’t audio cues to assist me set up an expectation for the way lengthy I want to attend earlier than it responds. There’s a click on sound when it begins processing my request, however then I might have to attend a number of seconds in silence earlier than listening to a response … perhaps it’s just one second or perhaps it’s 5 seconds. That stated, if I ask it to browse the online, then it performs a steady ready sound; internet shopping takes longer, perhaps 10 to twenty seconds, however a minimum of I get to listen to a “ready” sound. (I don’t thoughts ChatGPT taking longer right here since a human would additionally take extra time to browse the online. Nonetheless, internet shopping is annoying once I don’t explicitly ask it to browse. Oftentimes I desire a quick reply however one thing I say triggers a browse with out me meaning to.) In distinction, when talking with a human face-to-face, I can use visible cues to inform whether or not the opposite particular person is deep in thought or when they are going to doubtless reply; and even over the telephone the opposite particular person could say “ummm” or “maintain on one sec, lemme suppose” or “okay let me look this up on the internet, grasp tight for some time …” in the event that they want extra time to suppose by means of their response. Nonetheless, since I don’t get any of those verbal cues from ChatGPT, unpredictable wait occasions break the phantasm of speaking to an individual.Can’t interrupt whereas it’s talking: I at all times needed to watch for ChatGPT to fully end speaking earlier than it could hearken to my subsequent request. And since I by no means know forward of time how lengthy it deliberate to speak for throughout a selected flip (i.e., what number of phrases its LLM-generated response is), once I needed to say one thing halfway it was aggravating to have to attend. I later noticed that I might really interrupt it by tapping on the app on my telephone display, however since I used to be driving and hands-free, I couldn’t safely try this. Additionally, that looks as if a cumbersome interplay; I ought to be capable to simply speak once I wish to, even when it’s speaking. This limitation made the dialog really feel like we have been utilizing a walkie-talkie the place just one occasion can speak directly. And it’s not simply me—this idea of overlapping speech is extensively studied in linguistics and communication analysis. People naturally speak over each other for numerous causes, so not with the ability to do that with ChatGPT made our dialog really feel much less fluid. Even implementing a characteristic like a voice command for interruption could be nice, like perhaps if I say “pause” or “wait” then it might cease and await my request.Speech recognition errors: ChatGPT’s speech recognition system (presumably based mostly on OpenAI’s open supply Whisper mannequin) is superb, but it surely does at occasions misread what I’m saying. What’s stranger is that typically it thinks I stated one thing once I didn’t, perhaps as a result of it picked up on background rumbles in my automobile. A number of occasions I wouldn’t be saying something and out of the blue it responds out of the blue; and once I verify the written transcript later, it thinks that I stated one thing like “Thanks for watching!” (which I by no means stated). At different occasions it tries to prematurely finish the dialog regardless that I’m not accomplished, perhaps as a result of it mistakenly detected that I stated one thing alongside the strains of “Thanks …” with none follow-up. Misrecognizing phrases is forgivable, however I really feel that it shouldn’t ever interpret background sounds as phrases. In fact, if there have been different folks within the automobile with me and both they talked or I used to be speaking to them, then I might additionally perceive how ChatGPT would mistakenly interpret that as being a request for it; always-listening residence assistants like Alexa have had this difficulty for years. A extra superior AI would study to filter out each different folks’s voices and likewise infer once I was talking with another person and never it. As an illustration, when it detects that my sentence is method off matter, perhaps which means I’m talking with another person within the automobile; it might a minimum of ask me “Had been you speaking to me simply now?” when it’s unsure. Extra usually, the thought of explicitly asking me for clarification when it’s unsure would go a good distance towards making these interactions really feel extra human; that’s what I (a consultant human!) would do if I have been on a loud telephone reference to somebody and didn’t hear them clearly.Overly agreeable synthetic tone: Lastly, it’s nonetheless ChatGPT below the hood, so all of the common limitations of ChatGPT apply right here. Most notably, ChatGPT is tuned to be overly pleasant and overly agreeable (sounding like a customer support agent) so it would merely go together with no matter you are saying. Thus, by default it won’t be good at pushing again on you or difficult your considering in any significant methods, similar to the way you wouldn’t anticipate a customer support agent to problem what you say. Furthermore, the overly pleasant tone of its responses might come off as insincere and nearly sarcastic at occasions, regardless that that wasn’t the designers’ intent. Relatedly, it had an inclination to ask me superficial questions after it responds, which sound mildly condescending and break the move of our chat, like, “Sooo, what do YOU take into consideration the San Diego Zoo? What’s YOUR favourite a part of the zoo?!?” … when a standard human wouldn’t break the conversational move so awkwardly like that. Lastly, ChatGPT is skilled on knowledge on the general public web (and may browse the online to get extra up to date internet contents), so it gained’t do as nicely should you’re asking about issues that haven’t been mentioned a lot on-line.
To summarize the above limitations, chatting with ChatGPT on my telephone felt like utilizing a walkie-talkie over a loud channel to speak to an excessively agreeable however socially unaware customer support agent who has in depth data concerning the contents of the general public web.
Parting Ideas: Cautiously Optimistic In regards to the Future
Regardless of these limitations, I’m excited to see what’s in retailer for future voice interfaces to LLM-based AI instruments like ChatGPT. My early experiences of speaking with ChatGPT whereas driving gave me a glimpse into what many people have seen rising up in sci-fi reveals corresponding to Star Trek, the place folks can speak to an omnipresent pc to ask questions, maintain conversations, or difficulty instructions. Fingers-free operation isn’t helpful solely whereas driving—it might make computing actually ubiquitous by letting us seamlessly work together with computation whereas we’re within the midst of doing housekeeping, cooking, or childcare; and it might make computing extra accessible to broader teams of individuals, corresponding to these with mobility impairments.
We nonetheless have a protracted strategy to go, although. Proper now the ChatGPT iPhone app isn’t hooked as much as exterior instruments beside a primary internet browser, however with the just lately introduced GPT retailer (and sure upcoming LLM app shops from different firms) it would quickly be potential to hook up LLMs to a wide range of instruments that may handle our emails, procuring lists, private funds, residence automation, and extra. Latest analysis has began exploring these concepts by connecting ChatGPT to residence assistants corresponding to Amazon Alexa (2023 arXiv paper PDF). One other promising line of labor is healthier context consciousness: for example, Meta and Ray-Ban just lately introduced new Good Glasses which permit customers to speak with an AI assistant that may see what they’re seeing (evaluation from The Verge). In my driving situation, you may think about carrying these glasses and having the AI act extra like a passenger sitting alongside you within the automobile seeing what you see relatively than somebody on the opposite finish of a telephone name. Critically, a passenger can pause the dialog and let you know to observe the street extra rigorously in the event that they see a potential hazard forward; a future AI powered by such good glasses might be able to do the identical factor. Alternatively, vehicles at the moment are beginning to straight embed AI into leisure programs (e.g., Volkswagen announcement at CES 2024), so future iterations might combine cameras and 3D monitoring to enhance LLMs. One might additionally think about smartglasses-based multimodal interactions the place you level to things in any bodily setting and begin conversations with the AI assistant about your environment (try this MKBHD YouTube Brief displaying AI chat with good glasses).
In fact, these more and more intense ranges of AI interplay and automation include dangers, corresponding to consumer overreliance, unintended command execution, psychological or bodily well being hazards, and safety/privateness violations. Thus, will probably be necessary to design methods to each handle these dangers and educate customers about methods to safely function these more and more highly effective programs. Thanks very a lot for studying. Sooo, what do YOU take into consideration ChatGPT’s voice mode?!? What are YOUR favourite and least favourite elements?
