Brand Voice Agents

Custom Voices

Clone your voice in under two minutes. Use it everywhere.

Record about a minute of natural speech in the xAI console . Our pipeline verifies you're the voice owner, processes your recording, and delivers a production-ready voice model, all in under two minutes. Your custom voice inherits every TTS capability: speech tags , multilingual output, and both REST and WebSocket streaming.

PASSPHRASE CHECK RECORDING My voice is my key Step 1 Read a passphrase aloud to confirm your identity Custom voices work everywhere our built-in voices do. Pass the voice_id to any TTS endpoint or use it with the Voice Agent API for real-time conversational agents.

There is no extra charge to use Text to Speech or Voice Agent APIs with custom voices.

Voice Safety

Every custom voice goes through a two-stage verification process before it can be created. First, the speaker reads a verification phrase that our STT engine transcribes and matches in real time, confirming intent and presence. Then we compute speaker embeddings from the verification clip and the full recording to confirm they belong to the same person.

You can't clone a voice from a pre-existing recording, and you can't clone someone else's voice.

PASSPHRASE CHECK RECORDING My voice is my key Passphrase Check

Read a verification phrase aloud. Our STT engine transcribes and matches it in real time, verifying your consent and presence.

Speaker embeddings from the passphrase and the full recording are compared to confirm they belong to the same person.
