#DiffSinger

NATSpeech offers a scalable, non-autoregressive text-to-speech synthesis framework, designed with user-friendly PyTorch implementation. It supports high-quality models like PortaSpeech and DiffSinger and features data processing with Montreal Forced Aligner. The efficient approach ensures resource-effective training and inference. The framework promotes ethical use by restricting unauthorized speech synthesis of individuals. Discover the advanced capabilities of NATSpeech in next-gen speech synthesis.

DiffSinger employs a shallow diffusion mechanism for high-quality singing voice synthesis, providing tools for Text-to-Speech and Singing-Voice Synthesis. The project includes features like MIDI integration, pitch extraction, and advanced vocoders, including HiFiGAN and NSF-HiFiGAN. Designed for flexibility and speed, it incorporates enhancements like PNDM for faster processing and integrates seamlessly with datasets such as Ljspeech and OpenCpop. It includes comprehensive documentation and interactive demos on Hugging Face, with continuous development ensuring compatibility with PyTorch and features acknowledged in conferences like ACL and NeurIPS.

DiffSinger provides a PyTorch-based implementation for singing voice synthesis, using a shallow diffusion mechanism and pre-trained FastSpeech2 Auxiliary Decoder. It supports multiple model configurations—naive, auxiliary, and shallow—with TTS features like pitch, volume, and rate control. Designed for single and batch inference with pretrained models, the repository offers detailed guidance for comprehensive synthesis and training, while still in development for multi-speaker training.

OpenUtau is a user-friendly, open-source editor for vocal synthesis, compatible with diffsinger and UTAU voicebanks. Its intuitive MIDI editor and vibrato tools allow for efficient music creation, while pre-rendering enables quick project previews. Supporting multiple phonetic systems and languages, the platform is ideal for international users. OpenUtau includes a diffsingerpack with an integrated vocoder, facilitating streamlined synthesis processes on Windows, macOS, and Linux. The project encourages community contributions via an active developer roadmap and plugin opportunities.
