Livekit Agents Framework

Operator runs `python agent.py start` to register a worker against LiveKit Cloud. Worker prints 'registered' but no agent ever joins a room.

Worker registration only advertises availability — agents join rooms via (a) automatic dispatch matching the worker's room-name pattern, or (b) explicit AgentDispatchService.CreateDispatch from server code. Verify the dispatch path is wired; do not assume 'registered' implies 'joined'.

Agent is mid-TTS playback. User starts speaking. Agent's voice keeps playing for another 2s before stopping.

On VAD-detected user speech start, immediately stop TTS playback and cancel any in-flight LLM completion that produced upstream tokens for the now-stopped playback. Mark the assistant turn as interrupted and persist the partial assistant transcript in conversation history so the model knows what wa…

Operator wants to A/B test Deepgram STT vs AssemblyAI STT inside the same VoicePipelineAgent.

Both plugins implement the agents.stt.STT interface; swap by changing the stt= argument to VoicePipelineAgent. Preserve identical VAD and turn-taking config across the test arms; only the STT plugin should differ. Capture per-plugin latency + WER on the same room recordings.
