Google's Gemini Live and OpenAI's ChatGPT Voice Mode: The Latest in AI Conversation

Gemini Live could use some more rehearsals

What's the point of chatting with a human-like bot if it's an unreliable narrator -- and has a colorless personality? That's the question I've been turning over in my head since I began testing Gemini Live, Google's take on OpenAI's Advanced Voice Mode, last week. Gemini Live is an attempt at a more engaging chatbot experience -- one with realistic voices and the freedom to interrupt the bot at any point. Gemini Live is "custom-tuned to be intuitive and have a back-and-forth, actual conversation," Sissie Hsiao, GM for Gemini experiences at Google, told TechCrunch in May. "[It] can provide information more succinctly and answer more conversationally than, for example, if you're interacting in just text. We think that an AI assistant should be able to solve complex problems ... and also feel very natural and fluid when you engage with it." After spending a fair amount of time with Gemini Live, I can confirm that is more free-flowing and natural-feeling than Google's previous attempts at AI-powered voice interactions (see: Google Assistant). But it doesn't address the problems of the underlying tech, like hallucinations and inconsistencies -- and it introduces a few new ones. The un-uncanny valley Gemini Live is essentially a fancy text-to-speech engine bolted on top of Google's latest generative AI models, Gemini 1.5 Pro and 1.5 Flash. The models generate text that the engine speaks aloud; a running transcript of conversations is a swipe away from the Gemini Live UI in the Gemini app on Android (and soon the Google app on iOS). For the Gemini Live voice on my Pixel 8a, I chose Ursa, which Google describes as "mid-range" and "engaged." (It sounded to me like a younger woman.) The company says it worked with professional actors to design Gemini Live's ten voices -- and it shows. Ursa was indeed a step up in terms of its expressiveness from many of Google's older synthetic voices, particularly the default Google Assistant voice. But Ursa and the rest of the Gemini Live voices also maintain a dispassionate tone that steers far clear of uncanny valley territory. I'm not sure whether that's intentional; users also can't adjust the pitch, timbre or tenor of any of its voices, or even the pace at which the voice speaks, putting it at a distinct disadvantage to Advanced Voice Mode. You won't hear anything like Advanced Voice Mode's laughing, breathing or shouting from Gemini Live either, or any hesitations or disfluencies ("ahs" and "uhms"). The chatbot keeps an even keel, coming across as a polite but apathetic assistant -- as if Live has a multitude of conversations to handle and can't invest particular attention to yours. Chatting with Ursa When Google unveiled Gemini Live at its I/O developer conference in May, it suggested that the feature could be useful for job interview prep. So I decided to give that a go first. I told Gemini Live that I was applying for a tech journalism role, figuring I'd keep it simple and not step too far outside my area of expertise. The bot asked for details such as which specific job I might want within journalism (e.g. investigative versus breaking news reporting) and why, and then threw me a few generic practice questions ("Can you tell me a little about yourself?") interspersed with more personalized ones ("What do you enjoy most about tech journalism?"). I answered -- a few sentences per question, nothing crazy -- and asked Gemini Live for feedback. The chatbot was nothing if not complimentary. "Based on our practice, it sounds like you have a good handle on the challenges and rewards of tech journalism," it said. The glowing review seemed bit suspect to me, given my responses were completely off the cuff. So I tried throwing Gemini Live for a loop, disingenuously implying I'd only given one-word answers (I hadn't) and asking the bot whether it was still sure about its critique. It took the bait. "That's true, you mostly gave one-word answers," Gemini Live responded. "Can you tell me a little more about why you think you only gave one-word answers?" This sort of gaslighting, if you will, was a common thread in my chats with Gemini Live. The model, like all generative AI models, confidently makes stuff up -- a lot. And that makes it difficult to trust. Strange behaviors Gemini Live remembers a surprising number of things from earlier conversations in the same chat session; ask it to recount a story it told yesterday and there's a reasonable chance it will. But when it comes to queries about people, places and things -- queries you'd assume would be easier considering Gemini Live has Google Search at its disposal -- the bot's hallucinatory tendencies often rear their ugly heads. Early on a Friday evening, I asked Gemini Live for suggestions of budget-friendly things to do in New York City. It recommended the infamous nightclub Le Bain (which it bizarrely pronounced "Le Boulebouleboulebou"), a rooftop bar called The Skylark and a second club, Output, in Williamsburg. "Awesome!," I thought... before I did some Googling. Gemini Live had highlighted The Skylark's supposedly "superb" happy hour, but I couldn't find any mention of it on the bar's website. Output permanently closed in 2019. Le Bain wasn't a bad suggestion (it rarely charges cover) -- but the line to get in is often an hour or more. "You're absolutely right! Output has indeed closed its doors," Gemini said when I corrected it on the second point. "Thank you for catching that outdated information." I decided to switch gears, and had Gemini Live suggest a game to play. "I'll give you a word, and you have to create a new word using only the letters from the original word," proposed the chatbot. That sounded appealing -- until Gemini Live tried to convince me that the word "quiet" could be made from the letters in "cloud." Time for a new activity. Bored, I asked Gemini Live if it had any spicy takes. "The increasing focus on mental health awareness is doing more harm than good," Gemini responded. "By pathologizing normal human emotions and experiences, we're creating a generation overly reliant on medication and therapy, rather than fostering resilience and coping mechanisms. Boom!" Spicy to be sure -- and controversial! "That was a provocative statement designed to spark discussion rather than a well-rounded analysis of a complex issue," Gemini Live told me when I asked whether it was sure about what it said. "The increasing focus on mental health awareness is undoubtedly a positive development." Wishy-washy Gemini Live's dueling takes on mental health illustrate how exasperatingly nonspecific the bot can be. Even where its responses appear to be grounded in fact, they're generic to the point that they're not incredibly useful. Take, for example, my job interview feedback. Gemini Live recommended that I "focus my interview prep" and "practice talking about my passion for the industry." But even after I asked for more detailed notes with specific references to my answers, Gemini stuck to the sort of broad advice you might hear at a college career fair -- e.g. "elaborate on your thoughts" and "spin challenges into positives."mi Where the questions concerned current events, like the ongoing war in Gaza and the recent Google Search antitrust decision, I found Gemini Live to be mostly correct -- albeit long-winded and overly wordy. Answers that could've been a paragraph were lecture-length, and I found myself having to interrupt the bot to stop it from droning on. And on. And on. Some content Gemini Live refused to respond to altogether, however. I read it Congresswoman Nancy Pelosi's criticism of California's proposed AI bill SB 1047, and, about midway through, the bot interrupted me and said that it "couldn't comment on elections and political figures." (Gemini Live isn't coming for political speechwriters' jobs just yet, it seems.) I had no qualms interrupting Gemini back. But on the subject, I do think that there's work to be done to make interjecting in conversations with it feel less awkward. The way it happens now is, Gemini Live quiets its voice but continues talking when it detects someone might be speaking. This is discombobulating -- it's tough to keep your thoughts straight with Gemini chattering away -- and especially irritating when there's a misfire, like when Gemini picks up noise in the background. In search of purpose I'd be remiss if I didn't mention Gemini Live's many technical issues. Getting it to work in the first place was a chore. Gemini Live only activated for me after I followed the steps in this Reddit thread -- steps that aren't particularly intuitive and really shouldn't be necessary in the first place. During our chats, Gemini Live's voice would inexplicably cut out a few words into a response. Asking it to repeat itself helped, but it could take several tries before the chatbot would spit out the answer in its entirety. Other times, Gemini Live wouldn't "hear" my response the first go-around. I'd have to tap the "Pause" button in the Gemini Live UI repeatedly to get the bot to recognize that I'd said something. This isn't so much a bug as an oversight, but I'll note here that Gemini Live doesn't support many of the integrations that Google's text-based Gemini chatbot does (at least not yet). That means you can't, for example, ask it to summarize emails in your Gmail inbox or queue up a playlist on YouTube Music. So we're left with a bare-bones bot that can't be trusted to get things right and, frankly, is a humdrum conversation partner. After spending several days using it, I'm not sure what exactly Gemini Live's good for -- especially considering it's exclusive to Google's $20-per-month Google One AI Premium Plan. Perhaps the real utility will come once Live can interpret images and real-time video, which Google says will arrive in an update later this year. But this version feels like a prototype. Lacking the expressiveness of Advanced Voice Mode (to be fair, there's debate as to whether that expressiveness is a positive thing), there's not much reason to use Gemini Live over the text-based Gemini experience. In fact, I'd argue that the text-based Gemini is more useful at the moment. And that doesn't reflect well on Live at all. Gemini Live wasn't a fan of mine either. "You directly challenged my statements or questions without providing further context or explanation," the bot said when I asked it to scrutinize my interactions with it. "Your responses were often brief and lacked elaboration [and] you frequently shifted the conversation abruptly, making it difficult to maintain a coherent dialogue."

You've Got a Friend in... ChatGPT? I Tried Out the AI's New Voice Mode to Find Out

Lisa joined CNET after more than 20 years as a reporter and editor. Career highlights include a 2020 story about problematic brand mascots, which preceded historic name changes, and going viral in 2021 after daring to ask, "Why are cans of cranberry sauce labeled upside-down?" She has interviewed celebrities like Serena Williams, Brian Cox and Tracee Ellis Ross. Anna Kendrick said her name sounds like a character from Beverly Hills, 90210. Rick Astley asked if she knew what Rickrolling was. She lives outside Atlanta with her son, two golden retrievers and two cats. I don't have a relationship with ChatGPT despite lots of time spent using it. After all, it's just a generative AI chatbot with a knack for answering questions and creating text and images -- not a friend. But after I spent a few days talking with ChatGPT in its new Advanced Voice Mode, which went into a limited trial earlier this month, I have to admit I started to feel more of a bond. When OpenAI announced in its Spring Update that it would be enhancing ChatGPT's voice functionality, the startup said it wanted users to have more natural conversations. That includes ChatGPT understanding your emotions and responding accordingly now, so you're not just talking to a stoic bot. Pretty cool, right? I mean, who doesn't love a good conversation? But even OpenAI itself has some caveats about what this might mean. The new voice and audio capabilities are powered by the company's GPT-4o AI model, and OpenAI acknowledges that the more natural interaction could lead to anthropomorphization -- that is, users feeling the urge to start treating AI chatbots more like actual people. In a report this month, OpenAI found that content delivered with a human-like voice may make us more likely to believe hallucinations, or when an AI model delivers false or misleading information. I know I felt the impulse to treat ChatGPT more like a person -- especially since it has a voice from a human actor. When ChatGPT froze up at one point, I asked if it was okay. And this isn't one-sided. When I sneezed, the AI said "Bless you." Voice queries in traditional search have been around for more than a decade, but now they're all the rage among generative AI chatbots. Or at least two big ones, ChatGPT and Google Gemini. The latter's conversational Gemini Live feature made its public debut at the Made By Google event last week that also introduced a new lineup of Pixel phone and a raft of AI features. Besides the similarities in conversational skills, Gemini Live and Advanced Voice Mode are both multimodal, meaning the interactions can involve photos and video as well as audio. The idea has long been that most of us can talk faster than we type and that spoken language is a more natural interface for human-machine interactions. But a human-like voice changes the experience -- and perhaps even our relationship with chatbots. And that's the uncharted territory we're entering now. My access to Advanced Voice Mode came with the caveat that it is undergoing changes and there could be errors or times when it's not available. There are unspecified limits on how much you can use Advanced Voice Mode in a given day. OpenAI's FAQs say you'll receive a warning when you have 3 minutes left. Thereafter, you can use Standard Voice Mode, which is more limited in its ability to tackle topics and in offer "nuanced" responses. In my experience, Standard Voice Mode is harder to interrupt and is less likely to ask for feedback or to ask follow-up questions. It's also less likely to give unsolicited advice and to understand emotion. To access Advanced Voice Mode, you click on the voice icon in the bottom right corner when you pull up the ChatGPT app. You have to make sure the bar at the top of the screen says Advanced -- I made the mistake of having an entire conversation in Standard Mode first. You can easily toggle between the two. I had to choose one of four voices -- called Juniper, Ember, Breeze and Cove. (You can change later.) There was initially a fifth, Sky, but CEO Sam Altman suspended it after actor Scarlett Johansson called out OpenAI for the similarity to her own voice. I opted for Juniper because it was the only female voice, but also because two of the male voices -- Ember and Cove -- sounded alike. Then I gave ChatGPT microphone access and we were good to go. It's hard not to refer to the voice as "she" since it is female. During our conversation, I asked if I should call it ChatGPT or Juniper and she -- I mean, it -- said, "You can call me ChatGPT, though Juniper has a nice ring to it. Is that a name you like?" So it seems ChatGPT doesn't have complete self-awareness yet. Or at least Juniper doesn't. I started by asking what you can do with Advanced Voice Mode, but ChatGPT was as coy as OpenAI has been about it. "Advanced Voice Mode is designed to offer more dynamic and responsive conversations," the chatbot said. "With a bit more adaptability in depth, it can handle a wider range of topics and might offer more nuanced responses." My guess is this ambiguity is on purpose to not bias our experiences, so that we use our imaginations to try out a range of queries in this initial trial. (OpenAI didn't have an on-the-record comment.) Google's Gemini Live also seems pretty capable when it comes to being dynamic and responsive. My colleague Lexy Savvides got some hands-on time with it and found you can have some pretty in-depth conversations in a fairly natural way as if you're talking to a human. You can interrupt both Advanced Voice Mode and Gemini Live, you can ask both to explain topics in simple terms, and both will be accept multimodal inputs. But because Gemini is part of Google's ecosystem, you can also ask Gemini Live to take action in apps like Gmail, Google Maps and Google Calendar. ChatGPT can't do that. One of the first examples of Advanced Voice Mode that early users shared on social media was asking ChatGPT to mimic an airline pilot. I wanted to ask something in that vein, but it was a little tricky because I couldn't ask for a celebrity impersonation -- that could get OpenAI in hot water again -- so it had to be another job type with a distinct sound. (Accents are okay, too.) I went with challenging the OpenAI chatbot to mimic a fast-talking auctioneer, like this man, where you can't understand much beyond the prices he's calling out. It was a tall order, but I wanted to see what ChatGPT could do. "I'm curious if you can do an impression of an auctioneer, like a fast-paced auctioneer at an auction where a prized bull is for sale," I said. "I'm looking for an auctioneer who speaks really fast, where it's like you can almost not even understand them other than the numbers, do you know what I mean?" ChatGPT replied, "Got it." There were no words on the screen. The AI just went for it: "Alright, we've got a fine bull here. Do I hear 5,000? 5,000. Now, 6,000? 6,000. Do I hear seven? Seven. Can I get eight?" ChatGPT said. "It's all about keeping the momentum and excitement up. How was that?" It wasn't quite what I envisioned, but it wasn't bad. ChatGPT in Standard Voice Mode gave much the same response but seemed to want to go on endlessly and was hard to interrupt to stop. I tried to interject between 5,000, 6,000 and 7,000. It was already starting in on 8,000 before I finally got through with, "Okay, okay, okay. That was pretty good." Advanced Voice Mode also seemed more likely to solicit feedback to queries. I can see how this back and forth forges more of a relationship even if one of you isn't human. I felt compelled to offer encouragement -- think of the stage fright! And that's even though I know ChatGPT doesn't have feelings. It was World Elephant Day earlier this month, so I asked for ChatGPT's best elephant trumpet. Advanced Voice Mode delivered an okay elephant call. The one-second trumpet didn't sound so much like an elephant itself but rather like a person trying to sound like a elephant. But it was probably better than I could do myself. While in Standard Voice Mode, ChatGPT said its best trumpet was coming, but then it sort of went into thinking mode for a while. I asked if it was okay and it said, "I'm here -- just catching my breath after that elephant trumpet." I told it I didn't actually hear the elephant trumpet and asked it to try again. It worked the second time. Since ChatGPT supports more than 50 languages, I wanted to test out something more practical. Mandarin Chinese is one of the most widely spoken languages in the world, so I asked for help learning an initial word or phrase. "But go easy on me," I said. It started off with "ni hao," which means hello. It spoke the phrase, which is helpful, but I'd have appreciated seeing the pronunciation broken down on screen too. "It's a friendly and simple greeting. Want to give it a try?" ChatGPT said. While both voice modes were encouraging, Advanced Voice Mode tended to ask more follow-up questions, like, "Any other words or phrases you'd like to learn while we're at it?" In the case of "xiexie," or thank you, Advanced Voice Mode offered additional advice I didn't get in Standard Voice Mode: "The tones are important in Mandarin, so make sure to go down, then up." It felt like I was talking to a kind, knowledgeable friend. I know ChatGPT can do math -- we saw that in the Spring Update, but I was wondering about something harder. I have a friend who is a physics professor, so I asked for help. He sent the following problem: "A cannonball is fired at an angle theta above the horizon at an initial velocity v. At what time will the cannonball hit the ground? How far from the firing position will the cannonball land? You may neglect air resistance." I wanted to show ChatGPT a visual, but it wasn't obvious how to do that in Advanced Voice Mode. That didn't become clear until I Xed out, when I saw a transcript of our conversation in the chat window and the option to share photos and files. When I shared an image in the chat interface later, ChatGPT-4o had no trouble explaining how to solve for time of flight and range. But when I was talking to ChatGPT, I had to read the problem out loud. It was able to verbally explain how to solve the problem, but the visual component in the more traditional experience was easier to understand. For the record, ChatGPT arrived at the same answer as my professor friend for the first part: t = 2v sin(theta)/g. However, ChatGPT got a different answer for range. I'll have to show it to my professor friend to see what happened because it's all kind of Greek to me. If I'd had something like this in high school, I wouldn't have struggled so much with AP physics. Because Advanced Voice Mode supposedly can understand emotions and respond accordingly, I then tried to act as if I was really sad and said, "It's just so hard. I don't know if I'm ever going to get physics." While ChatGPT in Standard Voice Mode was nice and supportive, I'm not sure it really understood I was sad. But that could also be because I'm a bad actor. Advanced Voice Mode seemed to be more empathetic, offering, "We can break down the concepts into smaller steps or we can tackle a different kind of problem to build up your confidence. How does that sound?" See? This isn't your run-of-the-mill chatbot experience. It's blurring into something else entirely.
