自定义语音与语音库
xAI 这波‘声音克隆+管理’的更新很实用，安全验证做得细，创作品类和品牌方应该会喜欢，对开发者来说是个加分项，但不是那种能改变格局的大招。
xAI于2026年4月30日推出自定义语音和语音库功能。用户可通过约1分钟录音快速克隆声音，并在Grok文本转语音及语音代理API中即时使用，整个过程仅需2分钟。语音库提供集中管理平台，内置语音已超80种，支持28种语言。为确保安全，系统采用两阶段验证，包括实时转录匹配和说话人嵌入确认，以防止未经授权的克隆。这些功能适用于品牌代理、内容创作、无障碍辅助、多语言团队及游戏娱乐等多种场景，且使用自定义语音无需额外费用。

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

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.
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.

Voice Library
The Voice Library is a new section in the xAI console that organizes every voice available to your team, with your custom creations alongside our built-in voices. Browse, preview, and manage voices from a single page.
We've expanded our built-in voice catalog to over 80 voices across 28 languages. Listen to any voice across different scenarios before choosing one for your application.
There is no extra charge to use Text to Speech or Voice Agent APIs with custom voices.
