Usage

Converting AssemblyAI Transcripts

# Basic conversion
{:ok, bold_transcript} = BoldTranscriptsEx.Convert.from(:assemblyai, transcript_json)

# With paragraphs and sentences data
{:ok, bold_transcript} = BoldTranscriptsEx.Convert.from(:assemblyai, transcript_json,
  paragraphs: paragraphs_json,
  sentences: sentences_json
)

# Converting chapters to WebVTT
{:ok, webvtt} = BoldTranscriptsEx.Convert.chapters_to_webvtt(:assemblyai, transcript_json)

Converting Deepgram Transcripts

# Language parameter is required for Deepgram
{:ok, bold_transcript} = BoldTranscriptsEx.Convert.from(:deepgram, transcript_json,
  language: "en"
)

Output Format

The converted transcript follows Bold's unified format:
