Grok Voice API Demo: Build Voice Agents with xAI & LiveKit

Dec '25 (edited) • LiveKit

We're excited to announce our partnership with xAI to bring Grok's voice technology to developers worldwide. Millions of people already talk to Grok through xAI's apps and in Tesla vehicles. Now you can build with the same technology through LiveKit.What makes Grok different? Most voice AI systems convert speech to text, process it, then convert back to speech. Grok uses true voice-to-voice processing—it understands and generates speech directly. This means lower latency and preserved emotional context like laughter, whispers, and natural conversational flow. The new LiveKit Agents plugin for Grok Voice Agent supports:

- 5 distinct voice options

- 100+ languages

- Multimodal capabilities (generate images mid-conversation)

- Function callingReal-world applications:

This matters for customer service agents that need to detect tone and respond with empathy, healthcare applications where emotional context is critical, education platforms that adapt to student engagement, and accessibility services that require natural conversation. Get started in minutes:

We've made integration simple. With just 4 lines of code and one command to install, you can add Grok's voice capabilities to your application. The LiveKit Agents plugin handles all the WebRTC transport, turn detection, and voice streaming. Try the playground at https://grok.livekit.io or check our docs at https://lnkd.in/gdw9EkSx
