feat(voice-to-text): Web Worker (no freeze) + persistent model cache - #82
Merged
Conversation
Transcription ran on the main thread, so the whole page froze during inference — which on the larger 'Better' model + a 30s clip on a phone can take minutes and looks hung (it wasn't; a shorter clip completes fine). - Move inference into a dedicated Web Worker (stt.worker + stt.client). The main thread stays responsive: the audio player works, and progress updates flow. A single long-lived worker keeps the in-worker model cache warm across runs. - Show a live elapsed timer while transcribing (now that the thread is free), and warn that the 'Better' model is much slower on phones. 545 tests · lint clean · build green (stt.worker chunk emitted; transformers stays in workbox globIgnores).

…nload On mobile the browser can evict the cached Whisper model between sessions under storage pressure, forcing a re-download on refresh. Request persistent storage (navigator.storage.persist) so the origin's cache isn't evicted.

Follow-up to the report that the 'Better' model 'kept transcribing' ~1 min and looked hung. It wasn't broken — inference ran on the main thread so the page froze; a shorter clip completes fine (and Bahasa output is accurate).
