xAI Grok Voice Upgrade: 21 New Flagship Multilingual Voices

On July 7, xAI's Grok model received a major voice update, officially adding 21 flagship voices. This expansion significantly enhances Grok's voice output capabilities. Because the new voices are natively multilingual, Grok Voice can now cover more than 25 languages, and the features are available for developers and testers to experience on the xAI Console.

Key Details and Improvements

Alongside expanding the voice library, the xAI team has invested heavily in R&D to optimize voice naturalness. In addition to the 21 new voices, the 5 existing Grok voices (Ara, Eve, Leo, Rex, Sal) have also received audio quality enhancements. Developers can integrate and utilize these new voice capabilities via the Realtime Voice Agent API and TTS API.
