Grok Bot voice mode (xAI calls it voice chat) lets you talk to your Bot out loud and hear it answer, on desktop or your phone. The 11 November update added a speed slider and a card for each voice. Here’s how to start a voice chat, what you can change and how it differs from dictation and phone calls.
Key takeaways
- Voice chat is a live spoken conversation with one Bot.
- Works in the desktop app and on iPhone and Android.
- Change the voice, speed (0.5x to 2x) and language.
- Every call is saved with a full transcript.
- Want AI agents working by voice for your business? Claim a free strategy session.
What Grok Bot voice mode is
The chat docs describe a voice chat as “a live spoken conversation with one Bot: the Bot answers out loud and keeps listening until you hang up.” It works in the desktop app and the phone app. A Bot can also draw on your earlier calls and your recent chat with it, and after you hang up you can ask it about the call in chat.
1. Start a voice chat
- 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, then the Bot starts talking. The button only shows when the composer is empty, so if it’s empty and you still can’t see it, update Grok Bot.

2. Change the voice, speed and language
During a call you can Mute, Hang up or choose Show transcript to read along. In a call with your own Bot, Show settings changes the Voice, the Speed and the Language, and Auto-detect picks the language from what you say.
The 11 November changelog (v1.0.1) gave the Voice menu a Speed slider from 0.5x to 2x and a card for each voice, and a call’s settings show the same controls.
3. Rules worth knowing
- Only one voice chat runs at a time. Starting another asks End the current voice chat?, and End and Chat switches.
- Voice chat works with one Bot, not in group chats.
- On desktop you can voice chat with a teammate’s shared Bot from your own chat with it.
- You can open other chats while the call runs and choose Return to the voice chat to go back.
4. On your iPhone
The mobile docs add Siri and Shortcuts support, including a Start Voice Chat shortcut. A voice chat shows a Live Activity while you’re on the line. On an iPhone with an Action Button, set the Action Button to Shortcut → Grok Bot → Start Voice Chat, and press it again to hang up.

5. After the call
The conversation gets a Voice chat card with the call’s length. 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. If the line drops, Grok Bot tries to reconnect by itself first; if it can’t, the call ends with Voice chat failed and you start it again.
Voice chat vs dictation vs phone calls
| Feature | What it does |
|---|---|
| Voice chat | A live spoken conversation between you and your own Bot. |
| Dictation | Speech turns into text in the composer (Cmd/Ctrl+D on desktop), and the Bot replies in text. |
| Voice memo | The Bot replies with an audio clip you can play and read. |
| Phone calls | Your Bot rings a business for you. US only, and you confirm every call. |

My verdict
Try one voice chat to plan your day, set the speed you like, and read the transcript afterwards. If you think faster than you type, Grok Bot voice mode is the quickest way to hand work to your Bot.
