But haven't you been in situations like these?

Want to ask about a recipe while cooking
Want to check your next appointment while driving
Want to jot down an idea that came to you during a walk
Want an article read aloud when your eyes are tired

At times like these, the keyboard gets in the way.

With Grok Voice Mode, just speak and Grok answers you. Like an AI assistant straight out of a movie.

🔧 Key Features of Grok Voice Mode

① Real-Time Bidirectional Voice Dialogue

You:   "Grok, tell me three AI industry news stories today"
Grok:  "Sure — here are the three making headlines today.
        First... (answers naturally by voice)"
You:   "Tell me more"
Grok:  "Of course, let me expand on that..."

It's fine to interrupt mid-sentence. The interaction flows like a natural conversation.

② Sub-Second Latency

Response speed is under one second (sub-second). It replies at the same speed as natural human conversation.

③ 20+ Languages

Conversation is possible in 20+ languages, including Japanese, English, Spanish, French, and German. Switching languages is easy too.

④ Five Voice Variations

The Grok Text-to-Speech API offers 5 different voices. You can pick the one you like best.

⑤ Multimodal

You can show images while talking or ask about what's on your screen (subject to device support).
