Status: ✅ Completed

Implement the core speech recognition functionality using OpenAI Whisper with support for multiple model sizes.

Details

  1. Install OpenAI Whisper and its dependencies
  2. Create a WhisperTranscriber class that handles:
    • Loading different model sizes (tiny, base, small, medium, large)
    • Transcribing audio with word-level timestamps
    • Handling model caching
  3. Implement model download functionality for first-time use
  4. Add GPU detection and acceleration if available
  5. Create a configuration system for model selection
  6. Implement intelligent chunking for long audio files
  7. Add error handling for transcription failures

Test Strategy

Test with sample audio files of varying lengths and qualities. Verify word-level timestamps accuracy. Measure transcription speed and memory usage across different model sizes.
