WTM (Whisper Turbo MLX)

This repository provides a fast and lightweight implementation of the Whisper model using MLX, all contained within a single file of under 300 lines, designed for efficient audio transcription.

Installation

brew install ffmpeg
git clone https://github.com/JosefAlbers/whisper-turbo-mlx.git
cd whisper-turbo-mlx
pip install -e .

Quick Start

To transcribe an audio file:

wtm test.wav

To use the library in a Python script:

>>> from whisper_turbo import transcribe
>>> transcribe('test.wav', any_lang=True)

Quick Parameter

The quick parameter allows you to choose between two transcription methods:

  • quick=True: Utilizes a parallel processing method for faster transcription. This method may produce choppier output but is significantly quicker, ideal for situations where speed is a priority (e.g., for feeding the generated transcripts into an LLM to collect quick summaries on many audio recordings).

  • quick=False (default): Engages a recurrent processing method that is slower but yields more faithful and coherent transcriptions (still faster than other reference implementations).

You can specify this parameter when calling the transcribe function:

wtm --quick=True
>>> transcribe('test.wav', quick=True)

Acknowledgements

This project builds upon the reference MLX implementation of the Whisper model. Great thanks to the contributors of the MLX project for their exceptional work and inspiration.
