# BoldTranscriptsEx

> Elixir library for converting speech-to-text transcripts from AssemblyAI, Deepgram, Speechmatics, and Mistral to a unified Bold Video transcript format, with WebVTT subtitle generation.

BoldTranscriptsEx converts vendor-specific transcript JSON into Bold Transcript Format v2.0, a unified structure with metadata, utterances, and word-level timing. It also generates WebVTT subtitles with smart line breaking (42 chars max, 2 lines max) and speaker labels.
