MLX STT

Speech-To-Text/ASR/Transcribe with MLX (Apple Silicon) and opensource models (default GLM-ASR-Nano-2512) locally.

Free and Accurate. No api key required. No server required.

Requirements

• mlx: macOS with Apple Silicon
• brew: used to install deps if not available

Installation

bash ${baseDir}/install.sh

This script will use brew to install these cli tools if not available: - ffmpeg: convert audio format when needed - uv: install python package and run python script - mlx_audio: do the real job

Usage

To transcribe an audio file, run this script:

bash  ${baseDir}/mlx-stt.sh <audio_file_path>

• First run could be a little slow, since it will need to download model.
• The transcript result will be printed to stdout.
