Choose whisper.cpp if…
- whisper.cpp is primarily C++; faster-whisper is Python.
- Requirements: Requires C++ setup and knowledge; Needs audio files converted into a compatible format supported by `ggml`..
- You need a lightweight solution that does not require Python or PyTorch
When NOT to use whisper.cpp
- When you prefer to work with higher-level languages like Python which might offer more ease-of-use and extensive libraries
- If your project requires real-time speech transcription and has limited computational resources as `ggml` optimization might still require significant CPU/GPU power for high-performance
Choose faster-whisper if…
- faster-whisper is primarily Python; whisper.cpp is C++.
- Requirements: Requires Python 3.9 or higher.
- Tags unique to faster-whisper: deep-learning, quantization.
- 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.
