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'.

Operator builds a VoicePipelineAgent with Deepgram STT, OpenAI LLM, Cartesia TTS. End-to-end latency to first audible token is reported as 1.8s.

Latency budget composes: STT partial-to-final + LLM TTFB + TTS first-byte + SFU RTT. Each plugin reports its own metrics; verify which stage dominates before changing components. Aggregate p50/p95 numbers are [REQUIRES-VERIFICATION] and provider-coupled — do not claim a fixed total in customer-faci…

User says 'Hold on…' with a 1.2s pause mid-sentence. The agent interrupts and responds, treating the pause as end-of-turn.

Tune Silero VAD min_silence_duration (or equivalent) to a value larger than typical inter-word pauses for the target population (e.g., 800–1200ms for thoughtful speakers). Combine with a small grace window after partial-transcript stability. Do not rely solely on VAD with default thresholds.
