Subtitles Made Easy: Deepgram's New Open Source Captioning Packages

Deepgram has released open-source captioning libraries for Python and JavaScript that generate SRT and WebVTT subtitles from speech-to-text transcription data. Designed to work with Deepgram as well as other APIs, the packages use converter classes to transform API-specific JSON responses into a common word-level format containing timestamps and optional punctuation. They support speaker labels when diarization data is available, allow developers to build custom converters for unsupported services, and offer indirect Python support for Whisper through whisper-timestamped or Deepgram-hosted Whisper. The libraries can be installed through pip or npm and include straightforward functions for producing standard caption files, with a Streamlit demonstration showing their use on YouTube videos.
