# xAI Releases Grok Voice Think Fast 2.0 with Enhanced Speech Reasoning

> xAI has released Grok Voice Think Fast 2.0, which it calls its most capable speech-to-speech model, with stronger speech reasoning, more accurate transcription, and noticeably smoother conversations. It began routing to production as grok-voice-latest on August 5. The headline design goal is speed. The model is tuned so tool calls fire quickly, often completing before it has finished its first spoken sentence, which cuts the awkward pauses that make voice assistants feel sluggish. It is priced at $0.08 per minute of audio. Voice is quietly becoming the next competitive front in assistants, and low latency is the feature that decides whether people actually talk to these systems. By optimizing for fast tool execution rather than raw model size, xAI is targeting the specific thing that breaks the illusion of a real conversation. Whether it holds up against rivals will come down to how natural those exchanges feel in daily use.
