andresayac/edge-tts
Edge TTS is a Node or Bun package that allows access to the online text-to-speech service used by Microsoft Edge without the need for Microsoft Edge, Windows, or an API key.
Supports 36+ audio formats (MP3, WebM, OGG, WAV, PCM) with real-time streaming, word-boundary metadata extraction, and fine-grained prosody control (pitch, rate, volume). Reverse-engineers Microsoft Edge's internal TTS API through WebSocket communication, enabling access to neural voices without authentication. Provides both a programmatic TypeScript API and CLI tooling, with modular architecture for seamless integration into Node/Bun applications.
