Thanks — I’ll respond to each question you asked about LiveKit behavior. 1) Multiple messages to TTS • When you send multiple messages to the TTS component, LiveKit synthesizes and plays them consecutively (messages are queued). Repeated calls like

session.say()

are played in sequence unless you implement logic to interrupt or merge them. 2) Automatic messages after idle audio • LiveKit does not automatically send messages after a period of idle audio. You can implement that behavior in your application/agent by tracking last-speech timestamps or VAD events and triggering a message after your chosen timeout. 3) Audio clarity analysis • LiveKit does not provide a built-in metric that scores “clarity” (SNR/distortion). It does support VAD and integration with third‑party/preprocessing plugins (noise suppression, voice focus) to improve audio quality and downstream STT performance. For explicit clarity scoring you would need to run a separate analysis model or use an audio-quality plugin before STT. 4) Calling AWS AgentCore directly (boto3) vs using a LiveKit Agent intermediary • You cannot replace LiveKit’s agent pipeline components with an external agent directly; there is no documented way to bypass the LiveKit agent abstraction and have the LiveKit STT/LLM/TTS pipeline invoke an external AgentCore agent as a first‑class pipeline component. • The supported pattern is to keep a LiveKit Agent as the orchestrator and have it call AWS AgentCore (for example, via boto3) as a tool/function. You can put your boto3 calls inside that tool implementation so the LiveKit Agent delegates to your AWS agent while preserving LiveKit’s plugin/agent interfaces. If you want, I can: • Show a short example pattern for queuing/interrupting TTS messages. • Suggest a simple idle-timer implementation using VAD events. • Outline how to wrap boto3 calls in a LiveKit tool function so your AgentCore agent is invoked cleanly. Which one would you like first?
