## Description
|
|
|
|
<!-- SECTION:DESCRIPTION:BEGIN -->
|
|
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
|
|
|
|
<!-- SECTION:NOTES:BEGIN -->
|
|
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.
