xAI Expands Grok Voice with 21 New Multilingual Flagship Voices
xAI
xAI released 21 new flagship voices for Grok Voice on July 6, covering all 25+ supported languages for use cases including customer support, education, and entertainment. The original five Grok voices were also retrained for improved pacing and emphasis. The new voices are available via the Voice Agent API, Text-to-Speech API, and Voice Agent Builder.
Why it matters
Expands the total Grok Voice catalog from 5 to 26 voices and positions xAI's TTS platform more directly against ElevenLabs and Cartesia in the developer voice-agent market.
Importance: 2/5
Voice catalog expansion rather than new model; notable competitive move in TTS developer market.
