GitHub·medium signal

OpenMOSS/MOSS-TTS provides a complete open-source TTS pipeline: zero-shot voice cloning (8B), multi-speaker dialogue generation (8B), voice design from text prompts (1.7B), low-latency agent synthesis (1.7B), 48kHz sound effects (1.3B DiT), and a 0.1B CPU-first nano model. Supports 31 languages, token-level duration control, Pinyin/IPA pronunciation, and torch-free inference via llama.cpp + ONNX Runtime. The audio tokenizer achieves 0.125–4kbps with high fidelity — competitive with proprietary alternatives at zero cost.
