msjsc001/Anki-TTS-Edge

Built on Flet (Flutter for Python) with asyncio-driven async I/O, it leverages the `edge-tts` library to access 300+ neural voices while using `pygame` for low-latency multi-threaded audio playback with character-level timestamp alignment for real-time highlighting. The architecture decouples UI routing (home, history, settings) through a global state manager, implements clipboard monitoring via background polling threads to auto-trigger generation, and includes garbage collection with file hash tracking to prevent orphaned audio/metadata. An optional sidecar Kokoro offline engine can be toggled via settings for local TTS synthesis without increasing the main binary footprint.
