The fastest calibration there is.

If you already corrected SRT captions by hand, upload them here with their audio files. Every fix you ever made becomes a lesson your recognizer learns on day one — batch upload, one audio file per SRT, as many pairs as you like.

Drop your files here — or click to choose
Select audio files (MP3/WAV/M4A/MP4) and their matching .srt files together. Name them so each audio finds its SRT (e.g. ep01.mp3 + ep01.srt).

Files are processed, then deleted. Only your personal dictionary persists.
