Through Inworld’s integration with the LiveKit Agents framework, developers can use pre-built or custom voices alongside their choice of LLM and speech recognition models, with LiveKit handling realtime communication across web and mobile apps. The accompanying video takes a closer look at expressive delivery, including how TTS-2’s voice steering helped the team bring Expressive Mode to LiveKit Agents. “Inworld's TTS-2 marks a real step forward in emotionally expressive voice synthesis. When combined with the conversational intelligence of LiveKit agents, it enables interactions that feel genuinely human, responsive, nuanced, and alive in ways that feel natural.” - David Zhao, CTO, LiveKit Watch the video or read the full partner story for more on our work together:01271.8K

Now 80% of patient calls are fully handled by their agents, and most bookings take under a minute. Read more:631720.5K
- Two small models we trained for voice agents: turn detection knows when the user is actually done talking, adaptive interruption knows “uh huh” isn’t an interruption. Free for agents on LiveKit Cloud. Starting today, self-hosted agents can run them in production too: a free development allowance, then metered per request. The old monthly cap is gone.80593.8K

- Voice agents get built three ways: cascaded (STT, LLM, TTS), turn-based speech-to-speech, and full-duplex, where the model listens and talks at the same time. All three now run on LiveKit Inference: GPT-Live and GPT Realtime from @OpenAI, @grok Voice Think Fast from @xai, and Gemini Live from @GoogleDeepMind. One LiveKit Cloud key, one bill.161620256.9K
