TranscriptSync

Align existing transcripts to audio with word-level timecodes

Audio & SpeechFreemium

TranscriptSync takes an existing text transcript and its corresponding audio recording and produces word-level timecode alignment without requiring re-transcription. The tool handles transcripts that paraphrase or lightly edit the spoken content, matching semantic meaning when exact words don't align. It produces output in SRT, VTT, and JSON formats suitable for subtitle generation, searchable audio indexes, and interactive transcript players. Media companies use it to add timecodes to legacy transcripts that were produced without timestamps.
