Grok bot voice mode is a live spoken conversation with one of your Grok Bots. The Grok Bot docs call it voice chat: the Bot answers out loud and keeps listening until you hang up. It works in the desktop app and the phone app, and you start it with the waveform button in an empty message box.

Voice chat is not the same as the phone calls feature. Voice chat is you talking to your own Bot. Phone calls are the Bot calling a business for you, in the US only. That feature has its own guide: Grok Bot phone calls.

The four ways to use your voice with Grok Bot
Grok Bot has several voice features, and they are easy to mix up. Here is how the docs separate them:
| Feature | Who talks to whom | How the Bot replies | Where to start it |
|---|---|---|---|
| Voice chat | You and one Bot, live | Out loud, in real time | Start voice chat (waveform button) in an empty composer |
| Dictation | You speak, the app types | In text, after you send | Start voice input or Cmd/Ctrl+D on desktop; Start dictation on phone |
| Voice memo | The Bot sends you audio | A recording with a transcript | Play voice memo in the chat |
| Phone call | The Bot and a business | The Bot reports back how it went | Ask the Bot to make a call (US only) |
This guide is about the first row. The other three get a short section each further down.
How to start grok bot voice mode
- Open the chat with the Bot and leave the composer empty.
- Choose Start voice chat, the waveform button in the composer.
- Allow microphone access if your computer or phone asks.
The call shows Connecting… on desktop or Calling… on the phone, and then the Bot starts talking. While you are on the line the app shows Voice chat. On desktop the sidebar can also show Voice chat in progress.
The button only appears when the composer is empty. If you have typed anything, even a space, it is hidden. The docs say that if the composer is empty and you still cannot see the button, update Grok Bot.

Controls during a call
You get three controls on every call:
- Mute and Unmute for your microphone.
- Hang up to end the call.
- Show transcript to read along as you talk.
You can open other chats while the call keeps running. On desktop, choose Return to the voice chat to go back to it.
Voice, Speed and Language settings
In a call with your own Bot, choose Show settings to change three things:
- Voice: which voice the Bot speaks with.
- Speed: how fast it talks.
- Language: the language of the call. Auto-detect picks the language from what you say.
The Grok Bot changelog for version 1.0.1, dated 11 November 2026, added a Speed slider to the Bot's Voice menu that runs from 0.5x to 2x, plus a card for each voice. The same controls show in a call's settings. So you can set a Bot's default voice and pace once, then adjust them mid-call.
Limits to know before you rely on it
Voice chat has a few firm rules in the docs.
- One call at a time. Only one voice chat runs at a time. Starting another asks End the current voice chat?, and End and Chat switches you over.
- One Bot at a time. Voice chat works with a single Bot, not in group chats. Open that Bot's own chat to start a call.
- Shared Bots on desktop. On desktop you can voice chat with a teammate's shared Bot from your own chat with it.
The group chat limit is the one that catches people out. If you want several Bots involved, talk to one Bot by voice and ask it to hand work to the others. All of a user's Bots share one cloud computer, each with its own screen, so they can pass files and context between them. Bots run on Cursor-hosted cloud computers, so the work keeps going after you hang up.
When the connection drops
If the connection drops, Grok Bot tries to reconnect on its own first. A short drop usually picks back up without you doing anything. If it cannot, the call ends with Voice chat failed. The notice may say Connection lost, No connection or The call ended unexpectedly. Choose Dismiss, check your internet, and start the call again.
Microphone problems have their own fixes. If Grok Bot says microphone access was denied, allow it in your system settings. If it says no microphone was found, connect one. To pick which microphone the desktop app uses, open Settings and choose one under Microphone.

What you get after the call
When the call ends, the conversation shows a Voice chat card with the length of the call. Open it to read the full transcript.
If the call left work to do, the Bot may follow up in the chat with next steps or results. That is the real value. You can talk through a task while walking, hang up, and come back to the result in text. You can also ask the Bot about the call afterwards. Grok Bot may ask How was the call?, and you can answer Good or Bad to send feedback.
Dictation and voice memos
Dictation is voice typing. Your speech turns into text in the composer. You read it, edit it and send it like any other message, and the Bot replies in text. On desktop choose Start voice input, or press Cmd/Ctrl+D while the message box is focused. You can also hold the keys while you talk. On iPhone and Android use Start dictation. Stop dictation before you start a voice chat.
Voice memos go the other way. A Bot can reply with a recorded memo in the conversation. Choose Play voice memo to listen and Pause voice memo to stop. Expand the memo to read its transcript.
iPhone: Siri, Shortcuts and the Action Button
On iPhone, Grok Bot adds shortcuts you can run from Siri, Spotlight or the Shortcuts app. The list in the docs is List Bots, Send Message, Start Dictation and Start Voice Chat.
A voice chat shows a Live Activity while you are on the line, so you can see the call from the Lock Screen and the Dynamic Island.
On an iPhone with an Action Button, you can press it to talk to a Bot:
- Open your iPhone's Settings and choose Action Button.
- Swipe to Shortcut.
- Choose Grok Bot, then Start Voice Chat.
If you do not pick a Bot for the shortcut, Grok Bot asks which one. Press the button again while you are on the line to hang up. That turns the Action Button into a one-press line to your Bot.
Voice mode next to the rest of Grok Bot
Voice chat is a front door. The work still happens through the Bot's apps, files and cloud computer. If you want a Bot to sit in on group calls instead, see the Grok Bot meeting guide. To connect your own tools so the Bot can act on what you say, see Grok Bot custom MCP. Teams can reach shared Bots in chat through Grok Bot in Slack.

FAQ
Is Grok Bot voice mode the same as phone calls?
No. Voice chat is a live conversation between you and one Bot. Phone calls are the Bot calling a business for you, such as booking a table, and they are US only. The Grok Bot phone calls guide covers that feature.
Can I use voice chat in a group chat?
No. Voice chat works with one Bot at a time. Open that Bot's own chat to start the call.
How do I make the Bot talk slower or faster?
Open Show settings during a call with your own Bot, or the Bot's Voice menu, and move the Speed slider. The changelog lists a range of 0.5x to 2x.
Do I get a record of what was said?
Yes. After the call a Voice chat card shows the call length and the full transcript. If you want help turning those calls into finished work, book a free AI strategy session.
