Common questions

Are audio or video files uploaded for transcription?

No. The tool extracts audio and runs transcription locally in the browser, which is useful for private meetings, courses, and media notes.

What affects transcription accuracy?

Language, accent, background noise, volume, recognition tier, and segmentation strategy all affect accuracy. Clear speech works best.

Why does the first run take time?

The browser needs to prepare and cache speech recognition capability. Later runs can usually reuse cached resources.
