LiveKit said on March 19, 2026 that it trained an audio model that can distinguish real user interruptions from backchannels and other noise. The company’s blog says the feature is now generally available in LiveKit Agents, delivers 86% precision and 100% recall at 500 ms overlap speech, and is enabled by default in current Python and TypeScript agent SDKs.

LiveKit said on X that xAI’s Grok text-to-speech is now available in LiveKit Inference with low-latency streaming, telephony readiness, and support for more than 20 languages. LiveKit’s docs say developers can access `xai/tts-1` through LiveKit Inference without a separate xAI API key or use the xAI plugin directly with `XAI_API_KEY`.
