Typed relationship
whisper successor faster-whisperfaster-whisper builds on Whisper to provide speed optimizations using CTranslate2.Recommended - Offers significant performance improvements.
Choose whisper if…
- faster-whisper builds on Whisper to provide speed optimizations using CTranslate2.
- Tags unique to whisper: weak supervision.
- When you need a tool that leverages large-scale weak supervision to improve the accuracy and reliability of speech recognition.
When NOT to use whisper
- In scenarios necessitating real-time processing where delays associated with large-scale model inference cannot be tolerated.
- If your project strictly requires open collaboration licensing terms beyond the permissive nature of MIT license, such as those which enforce sharing improvements back into the original repository.
Choose faster-whisper if…
- Requirements: Requires Python 3.9 or higher.
- faster-whisper builds on Whisper to provide speed optimizations using CTranslate2.
- Tags unique to faster-whisper: deep-learning, inference, quantization, speech-to-text.
- Also covers Inference & Serving.
- A package for faster speech-to-text transcription based on the Whisper model, using CTranslate2.
When NOT to use faster-whisper
- * When needing to employ FFmpeg directly for audio processing as it does not require FFmpeg installation and relies instead on PyAV.
- * In environments where additional dependencies from PyAV may introduce complexity or issues.
