Grok Voice

by xAI

Grok Voice is a real-time bidirectional voice agent for building conversational applications over WebSocket with low-latency turn-taking. It handles speech-to-speech interactions with automatic voice activity detection, supports 20+ languages with native-quality accents, and offers five voices (Eve, Ara, Rex, Sal, Leo) plus custom voice options. The model integrates tools including web search, X search, document retrieval, and custom function calling via JSON schema, enabling agents that fetch live data and take actions mid-conversation. It maintains session context for resumption (history is dropped after 30 minutes of inactivity), supports DTMF phone keypresses, and is compatible with the OpenAI Realtime API, which keeps migration straightforward for developers familiar with that standard. On independent benchmarks from Artificial Analysis, Grok Voice leads the Tau Voice Bench and scores 92.3% on Big Bench Audio for speech reasoning, surpassing Gemini 2.5 Flash Native Audio and GPT Realtime.
