Talk to Gemini Notebook (formerly NotebookLM): Live Voice Chat Guide

You are on a train with a notebook full of lecture notes, and typing questions on a phone is tiring. Can you just talk to it? Yes. Gemini Notebook (formerly NotebookLM) has Live voice chat. It is a real-time spoken conversation with one notebook. It answers from the sources, and you can interrupt it mid-sentence. It lives in the mobile app, and it is not the same as talking to the podcast hosts. This guide shows how to start it, who has it, and what to say once it is listening.

Can you talk to Gemini Notebook?

Yes, out loud and in real time. Live voice chat is Gemini Notebook’s spoken chat mode: you talk to one notebook, it talks back, and you can cut in at any point. Google’s help center calls it “a natural, free-flowing conversation” in which “every answer is grounded in your uploaded sources”, and you can interrupt at any moment (Gemini Notebook Help, 2026). Its own examples of when to cut in are adding more details or changing the topic. Google’s announcement frames it as a study tool. Because every response is grounded in your sources, it says, “you can get step-by-step guidance, ask questions and interrupt at any time just by speaking,” in nearly 100 languages (Google, 2026).

Three different features get mixed up here, and the searches show it. When we pulled Google autocomplete for this post on October 26, 2026, “talk to notebooklm” completed to “can you talk to notebooklm” and “how do i talk to notebooklm”. It also completed to “notebooklm talk to hosts” and “notebooklm talk to podcast”, while “notebooklm live” brought up “notebooklm gemini live”. So here’s the map: three voice features, three different listeners.

Gemini Live is the one that can’t help here. Google’s own page says “Gemini Live does not have access to Gems or Notebooks”, so it can’t answer from your notebook (Gemini, 2026). If you want to talk to your sources, open the notebook, not the Gemini app.

How do you start Live voice chat in Gemini Notebook?

Open a notebook in the mobile app and tap Audio in the chat box. Google’s steps are short (Gemini Notebook Help, 2026):

1. Open the Gemini Notebook app on your phone or tablet.
2. Pick an existing notebook, or create a new one.
3. At the bottom right of the chat box, tap Audio.
4. Start talking.
5. Tap Mic to mute yourself, and tap Close to end the session.

The conversation doesn’t vanish when you hang up. Google says you can see transcripts of your interactions in chat, so you can read back what was said. That’s handy, for example, when an answer you heard on a walk turns out to matter later. Google also adds a courtesy note: ask permission before you record other people or include them in a chat.

What if you don’t see the Audio button?

Run through four checks before assuming it’s broken:

• Your age on the account. Google limits Live voice chat to users 18 and over.
• The app, not the browser. Google documents it for the Gemini Notebook mobile app only.
• Your plan. Pro and Ultra have it, as the next section explains. On Plus or the free plan, Google hasn’t said.
• The app version. Update Gemini Notebook from Google Play or the App Store, then reopen the notebook.

Who can use Gemini Notebook voice chat?

Anyone 18 or older with Google AI Pro or Ultra, in the mobile app. The help page names only two conditions, age and the app. The plan detail comes from the official Gemini Notebook account on X. It says Live Chat is “100% rolled out to all Ultra users on mobile”, and Live Voice Chat is “100% rolled out to all Pro users on mobile” (Gemini Notebook on X, 2026). For Google AI Plus and the free plan, Google hasn’t said either way. Its plans page does explain the pattern, though. Under “Earlier Access to Key Features”, it rates the free plan Standard, Plus Early, and Pro and Ultra Priority (Gemini Notebook Help, 2026). In other words, paid tiers get headline features, such as Live voice chat, first by design. Google lists current plan prices on its Google AI plans page.

The app itself isn’t offered in every country, and Google’s mobile app page lists where it is. Usage is the other open question, since Google doesn’t publish what a voice session costs against your allowance. Its usage page says limits factor “the models and features you use” and “the length of your chat,” and refresh every five hours until a weekly cap (Gemini Notebook Help, 2026). So if you’re close to the line, keep sessions short. Our usage limits guide shows how to stretch them.

Can you use voice chat on the web?

Not with Live voice chat, which Google documents only for the mobile app, even though the same mobile app page recommends the desktop version “for the full Gemini Notebook experience” (Gemini Notebook Help, 2026). On a computer, you have two spoken routes instead:

1. Dictate your question. Your operating system can type what you say into the chat box. On Windows, press Windows key+H for voice typing (Microsoft Support, 2026). On a Mac, choose Edit > Start Dictation or press the Microphone key (Apple Support, 2026). The answer comes back as normal typed chat, with citations you can open.
2. Join an Audio Overview. Interactive mode lets you speak to the hosts in the browser, in English. It’s a different tool, though, as the next section shows.

Live voice chat vs Join mode: which one should you use?

Use Live voice chat to question your sources. Use Join when you’re already listening to an Audio Overview and want the hosts to explain something. Both let you speak, but you’re talking to different things.

Interactive mode is the Audio Overview’s way to join the conversation. You create a new Audio Overview, select Interactive mode, select Join while you listen, and ask when the hosts call on you. They answer “based on your sources” and then “resume the original Audio Overview” (Gemini Notebook Help, 2026). It’s English only, it works only on newly generated overviews, and the mobile app labels it Beta.

	Live voice chat	Audio Overview Join (interactive mode)
Who answers	The notebook, as in chat	The two AI podcast hosts
Where you start	The Audio button in the chat box	Studio: a new Audio Overview, then Interactive mode, then Join
Where it works	Mobile app (Android, iOS)	Web, and the mobile app as Beta
Languages	Nearly 100	English only
Who sets the pace	You do; interrupt any time	The episode does; you ask when the hosts call on you
What’s kept	Transcripts show in chat	Your voice and transcribed questions aren’t stored or shared
Best for	Questions, self-quizzing, step-by-step help	Side questions during an overview

Pick by who’s driving. Want the material presented to you, with the option to ask “wait, what does that term mean?” Generate an interactive Audio Overview. Want answers to your own questions, in your order, maybe in Spanish or Hindi? Use Live voice chat. Studying for an exam? Use both, in that order: listen to an overview first, then use voice chat to quiz yourself on it. Our Audio Overview guide covers formats, languages and how to steer the hosts.

How does grounding work in voice answers?

The same way it works in typed chat: answers come from your sources, not from the open web. Google says Live voice chat answers are grounded in your uploaded sources, and its general rule is that “chat responses in Gemini Notebook only use data from your sources” (Gemini Notebook Help, 2026). Ask about something your sources don’t cover, and the right reply is “your sources don’t say”, not a confident guess. If you hear a guess, that’s your cue to check.

What voice takes away is the easy check. In typed chat, every claim carries citations: hover over one for the full quote, or select it to jump to the passage in context (Gemini Notebook Help, 2026). Google doesn’t say whether spoken answers come with those citations. Its mobile app page also warns that chat responses and artifacts, “including voices,” may contain inaccuracies or audio glitches (Gemini Notebook Help, 2026).

So split the work: use voice to explore and understand, then use typed chat for anything you’ll quote, submit or act on. Three habits help:

• Ask for the source by name. “Which source says that?” ties the answer to a document you can open later.
• Ask it to flag silence. Start with “If my sources don’t cover something, say so.”
• Re-ask the keepers in typed chat. The typed answer comes back with citations you can open.

Notebook scope matters too: the mobile chat has a source selector in the prompt box, but Google doesn’t say whether Live voice chat follows it. A notebook built around one topic is therefore the surer way to keep spoken answers on topic. For the failure modes worth checking first, see does Gemini Notebook hallucinate?

How do you keep what you learned by voice?

Read the transcript, then save the answers that matter. Google shows voice turns as transcripts in chat (Gemini Notebook Help, 2026). Natively, you save one reply at a time with Save to note, and a note can go to Google Docs with Export to Docs (Gemini Notebook Help, 2026). Google documents no button that exports a whole chat.

Kortex is a free Chrome extension for Gemini Notebook, and we built it, so weigh this part accordingly. It runs in Chrome on your computer, not in the mobile app. There, it adds Export and Copy buttons to the chat. Export saves the whole chat, or only the replies you tick, as PDF, Markdown, text or JSON, and each citation stays next to its claim as a source label. Copy puts the chat on your clipboard as Markdown, free. The free plan includes 10 exports a day. A routine that works with what Google documents: talk it through on your phone, then at your desk re-ask the two or three answers worth keeping in typed chat, and export them with their citations. Our guide to exporting Gemini Notebook covers every other route out.

What should you say to Gemini Notebook?

Talk to it like a tutor with your notes open, not like a search box. Spoken prompts work best when they’re short, do one job per turn and set the rules up front. Start with “quiz me”, because recalling an answer does more for memory than hearing it again. In a classic study, students who took recall tests on prose passages retained substantially more after two days and after a week than students who simply restudied, even though restudying made them more confident (Roediger and Karpicke, PubMed, 2006). A voice quiz is that test, run by your own notebook. Here are openers worth borrowing:

Say this	What it’s for
”Quiz me on chapter three, one question at a time. Wait for my answer, then tell me if I’m right.”	Active recall on a walk
”Explain [concept] in two sentences, then ask if I want more.”	Short answers you can extend
”What do my sources say about [topic]? If they don’t cover it, say so.”	Keeping answers honest
”Walk me through [process] step by step, and wait until I say next.”	Hands-busy tasks, such as a lab or a recipe
”Which source says that?”	Tying a claim to a document
”Compare what [source title] and [source title] say about [topic].”	Spotting where sources disagree
”Ask me questions about [source] in Spanish and correct my answers.”	Language practice on your own material

Then use the interrupt. “Stop, shorter.” “Go back to the second point.” “Skip that, next one.” Interrupting is the whole point of Live, so there’s no reason to sit through a long answer you didn’t want. And when you need a moment to think, tap Mic to mute instead of filling the silence.

When should you talk, and when should you type?

Talk when your hands or eyes are busy, or when saying an idea out loud is the point. Type when you need evidence on the page.

• Talk: reviewing on a commute, quizzing yourself before an exam, rehearsing an explanation, or practising one of the nearly 100 languages Google says it supports. It also helps whenever typing is hard.
• Type: quoting citations, comparing many sources, building tables, generating files or Studio outputs, and anything you do on the web.

Our own survey data points the same way. When we analyzed the 776 answers to the Kortex MCP waitlist survey (then in private beta, Sep-Oct 2026), 110 people asked for cited notebook answers inside their AI assistant. Only 6 of the 776 asked for voice or mobile access. The people wiring notebooks into their AI tools want evidence they can use at a desk; voice is for the moments away from it.

If your desk work happens in Claude or ChatGPT, that’s where Kortex MCP fits. It’s a bridge: your AI client asks a notebook through the Kortex extension in your own Chrome, and Gemini Notebook answers from your sources, with citations that come back into the chat. It’s included with Kortex Pro ($9.99 a month, or $9 a month billed yearly) and Lifetime ($199 once). Our guide to connecting Gemini Notebook to Claude and ChatGPT walks through the one-URL setup.

So, the short version: tap Audio in the app to talk to a notebook, press Join to talk to the hosts, and type when you need the receipts.

Frequently asked questions

Does NotebookLM have voice chat?

Yes. Gemini Notebook (formerly NotebookLM) has Live voice chat in its Android and iOS app. Open a notebook, tap Audio at the bottom right of the chat box and start talking. Every answer is grounded in your sources, you can interrupt at any moment, and transcripts appear in chat.

Can you talk to NotebookLM on a computer?

Not with Live voice chat, which Google documents for the mobile app only. On a computer, you can dictate a question into the chat box with your system’s voice typing (Windows key+H on Windows, Edit > Start Dictation on a Mac), or join an interactive Audio Overview, which speaks English only.

Which plans include Gemini Notebook voice chat?

The official Gemini Notebook account says Live voice chat is fully rolled out to Google AI Pro and Ultra users on mobile. Google hasn’t said whether Plus or free accounts have it. Its help page adds that the feature is for users 18 and over.

What’s the difference between Live voice chat and interactive mode?

Live voice chat is a conversation with the notebook itself, in nearly 100 languages, started from the chat box. Interactive mode is part of an Audio Overview: you select Join while it plays and ask the AI hosts a question, in English only, and then the episode picks up again.

Can Gemini Live talk to my notebooks?

No. Google’s Gemini Live page says it does not have access to Gems or Notebooks. To talk to your sources, use Live voice chat inside the Gemini Notebook app instead.

Are voice chats in Gemini Notebook saved?

Google says you can see transcripts of your Live voice chat in chat. Interactive mode works differently: Google says your voice and transcribed questions to the Audio Overview hosts aren’t stored or shared.
