About Grok Voice Transcribe 2.0
Grok Voice Transcribe 2.0 (API id grok-voice-transcribe-2.0) is an xAI speech-to-text / ASR model, announced September 18, 2026 on x.ai/news. Specialized transcription API, not a chat LLM. First-party: twice as accurate as Grok Voice Transcribe 1.0 at the same price; multilingual (dozens of languages, auto language detect, mid-recording language switch); batch and streaming STT; word-level timestamps with confidence; speaker diarization at no extra cost; multichannel up to 8 channels; key-term biasing (up to 100 terms); text formatting for numbers/dates/currencies/phones/emails.
