Browser recordings can be captured and played back immediately here. Stored recordings can now be submitted to transcription runs with different tools, runtimes, and models.

Transcription Workbench

This PoC keeps the recording source separate from the transcription engine. That lets the same stored audio be compared across local and hosted tools while logging latency for each run.

Set FASTER_WHISPER_MODEL_PATH to prefill a local model directory.

Default is 2 seconds. This controls how long Twilio waits after silence before submitting the caller's speech turn.

Faster Whisper

Local transcription via faster-whisper.

Twilio Native

Twilio callback-based transcription placeholder for comparison.

Transcript

In Xanadu, the Kublikon, a state-led, pleasure-don't-decreate, were elf the sacred river ran through Kevin's visualist to man, down to a cellulosee. So, twice five miles of fertile ground, with walls and towers with good old ground, and there were gardens, bright with sinuous rules, where, ah, we're blossomed many an incense bear in tree, and here were forests ancient as the hills, in folding sunny spots of greenery.
