New multilingual voices for Grok Voice, plus improved naturalness for the original five.
Today, we're releasing 21 new flagship voices for Grok Voice, joining the original five. All of them are multilingual and available now in the realtime Voice Agent API, the Text to Speech API, and the new Grok Voice Agent Builder. Meet the newcomers in the lineup:
Each voice was cast for a specific job: support, characters, commentary, advertising, education. Speech tags like [pause] and <whisper> can be used to control the delivery. Hear five of them in their element:
Thanks for your patience — I found the issue. [pause] Your account was still on the legacy plan, so I've moved you over and <emphasis>applied the credit to this month.</emphasis> <soft>You're all set.</soft> Anything else I can take care of?
Every voice is natively multilingual, supporting all of Grok Voice's 25+ languages.
闭上眼睛，静静聆听片刻。每一个声音都在讲述一个故事，每一个故事都值得被倾听。无论你身在世界的哪个角落，我都很高兴你在这里。
Ara, Eve, Leo, Rex, and Sal got an upgrade alongside the new voices. They've been retrained with an improved recipe, so pacing, phrasing, and emphasis are more natural.
To build a custom voice agent with one of the new voices, use the Grok Voice Agent Builder in the xAI console. You can also clone your own voice from about a minute of audio.
