Description

Verify live streaming transcription works end-to-end: browser AudioWorklet -> WSS via Cloudflare tunnel -> voice-command VAD -> Whisper -> finalized segments back to browser. Check: 1) WSS upgrade works through Cloudflare (may need websocket setting enabled), 2) No idle timeout kills the connection during pauses, 3) Segments appear ~1-2s after silence detection, 4) Text never shifts once displayed, 5) Batch fallback works when WS fails.

Implementation Notes

WebSocket streaming through Cloudflare tunnel: VERIFIED WORKING

  • WSS upgrade succeeds
  • Binary PCM16 data transmission works
  • Server responds with done message
  • No idle timeout issues observed
  • VAD correctly ignores non-speech (pure tone test)
  • No crashes in handler (torch tensor fix applied) Remaining: need real speech test via browser to confirm full transcription flow

CPU-only torch rebuild verified: health check OK, WebSocket OK. Still need browser-based real speech test for full E2E verification.

WSS through Cloudflare: verified working. VAD correctly rejects non-speech. Diarization endpoint: 200 OK. Offline Whisper fallback: deployed. Full browser real-speech test deferred to manual QA.
