x.ai grok Update

xAI introduces Custom Voices and the Voice Library for Grok Text to Speech and Voice Agent APIs. Teams can clone a voice from a short recording, manage voices in the xAI console, and use the new catalog of 80+ voices across 28 languages.

• Custom voices cannot be cloned from pre-existing recordings or from someone else's voice.

• Custom Voices let users clone a voice from a short recording and use it in Grok Text to Speech and Voice Agent APIs.

• Built-in voice catalog expanded to over 80 voices across 28 languages.

• Record about a minute of natural speech in the xAI console to create a custom voice.
• Pass the voice_id to any TTS endpoint or use it with the Voice Agent API for real-time conversational agents.
• Custom voices include speech tags, multilingual output, and REST/WebSocket streaming support.
• There is no extra charge to use Text to Speech or Voice Agent APIs with custom voices.
