About edge-tts
rany2/edge-tts
Use Microsoft Edge's online text-to-speech service from Python WITHOUT needing Microsoft Edge or Windows or an API key
Leverages Microsoft Edge's cloud TTS API by reverse-engineering the WebSocket protocol it uses, providing async Python bindings alongside CLI tools (`edge-tts`, `edge-playback`) for batch synthesis. Supports 100+ neural voices across languages with prosody control (rate, pitch, volume), subtitle generation, and integrates with automation frameworks like Home Assistant.
About obsidian-edge-tts
travisvn/obsidian-edge-tts
Free, high quality text-to-speech for your Obsidian notes, leveraging Microsoft Edge's Read Aloud API.
Supports native mobile playback on iOS and Android, queuing multiple notes for continuous narration, and generating embeddable MP3 files directly within notes. The plugin reverse-engineers Microsoft Edge's undocumented TTS API to bypass authentication, offering dozens of voices across multiple locales without requiring API keys or paid services. Integrates deeply with Obsidian's command palette, right-click context menus, and status bar while maintaining a floating playback controller with adjustable speed and loop options.
