RealtimeTTS and py3-tts
RealtimeTTS is a streaming-focused synthesis engine that could use py3-tts as an alternative offline TTS backend, making them **complements** — one optimizes for latency/interactivity while the other prioritizes simplicity and offline independence.
About RealtimeTTS
KoljaB/RealtimeTTS
Converts text to speech in realtime
Supports 15+ TTS engines (OpenAI, Elevenlabs, Azure, Coqui, Piper, and local models) with automatic fallback mechanisms for reliability, enabling flexible deployment from cloud APIs to on-device processing. Features sentence-boundary detection via NLTK or Stanza for streaming text inputs compatible with LLM outputs, minimizing latency while maintaining natural speech segmentation across multilingual content.
About py3-tts
thevickypedia/py3-tts
Offline Text To Speech library for python
Wraps platform-specific TTS engines (SAPI5 on Windows, eSpeak cross-platform, AVSpeech/NSSpeechSynthesizer on macOS) to provide a unified API for voice synthesis with configurable rate, volume, and voice selection. Supports saving audio output to files and enables voice customization across different system-installed voices without requiring external API calls or internet connectivity.
