Pipecat pipeline simulator — VAD ➜ Smart Turn v3.2

Replays an audio clip through the exact logic pipecat runs in a live call:

audio chunks → Silero VAD → (after stop_secs of silence) → Smart Turn v3.2

The Silero VAD state machine and the Smart Turn audio-buffering / segment extraction are faithfully ported from pipecat. Every time VAD detects the user stopped speaking, the buffered segment is handed to Smart Turn and the end-of-turn decision is reported — with the exact audio that was fed to the model playable per turn.

All VAD and Smart Turn parameters are editable in the UI:

VAD: confidence, start_secs, stop_secs, min_volume
Smart Turn: pre_speech_ms, max_duration_secs, stop_secs fallback, decision threshold
Simulation: chunk size, trailing silence

Inference (Silero VAD + Smart Turn ONNX models) runs on the Space CPU via onnxruntime.
