- Created PiperTTSService with pitch shifting (-12 to +12 semitones) - Created UnifiedTTSService to manage multiple TTS engines - Added engine selection endpoints (GET/POST /api/tts/engines) - Added voices listing endpoint (GET /api/tts/voices) - Added pitch_adjustments parameter to TTS generation - Created install_piper.sh for easy Piper installation - Updated backend README with multi-engine documentation - Created comprehensive PIPER_TTS_GUIDE.md - Added TTS_ENGINE environment variable for engine selection - Updated requirements.txt with piper-tts and pydub This allows users to choose between Kokoro (high quality) and Piper (fast with pitch control) TTS engines at runtime.
