Decision brief

Faster Whisper is a Python library for fast speech-to-text transcription using Whisper models with CTranslate2 for inference, offering an alternative to installing FFmpeg by bundling FFmpeg libraries with PyAV.

Good fit when

  • When you need fast speech-to-text transcription without the need to install FFmpeg separately, as Faster Whisper bundles FFmpeg libraries with PyAV.
  • When you require a lightweight solution that simplifies the setup process by eliminating the need for external FFmpeg installation.

Avoid when

  • When your project strictly requires the use of FFmpeg for audio decoding, as Faster Whisper uses PyAV for this purpose.
  • When you are working in an environment where Python 3.9 or greater is not available, as this is a requirement for using Faster Whisper.
Requirements:
Requires Python 3.9 or greater.
