Free and Fast. 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

Usage

To generate audio from text, run this script:

bash ${baseDir}/mlx-tts.sh "<text>"

   "filePath": "<filepath>"
}
