@lively-winter-88668 is it possible to use offline STT (whisper) and TTS module with livekit? i have tried but its not working and referring this document "https://docs.livekit.io/agents/models/stt/#vad-and-streamadapter" Thanks

Not offline, no. But we support whisper-based models through several inference/plugins, such as https://docs.livekit.io/agents/models/stt/inference/cartesia/. That document you linked is talking about running STT without an AgentSession, which I don't believe you were asking about.
