Add plug-in [PNDM](https://arxiv.org/abs/2202.09778), ICLR 2022 in our laboratory, to accelerate DiffSinger freely. - Jul.27, 2022: Update documents for [SVS](docs/README-SVS.md). Add easy inference [A](docs/README-SVS-opencpop-cascade.md#4-inference-from-raw-inputs) & [B](docs/README-SVS-opencpop-e2e.md#4-inference-from-raw-inputs); Add Interactive SVS running on [HuggingFace🤗 SVS](https://huggingface.co/spaces/Silentlin/DiffSinger). - Mar.2, 2022: MIDI-B-version. - Mar.1, 2022: [NeuralSVB](https://github.com/MoonInTheRiver/NeuralSVB), for singing voice beautifying, has been released. - Feb.13, 2022: [NATSpeech](https://github.com/NATSpeech/NATSpeech), the improved code framework, which contains the implementations of DiffSpeech and our NeurIPS-2021 work [PortaSpeech](https://openreview.net/forum?id=xmJsuh8xlq) has been released. - Jan.29, 2022: support MIDI-A-version SVS. - Jan.13, 2022: support SVS, release PopCS dataset. - Dec.19, 2021: support TTS. [HuggingFace🤗 TTS](https://huggingface.co/spaces/NATSpeech/DiffSpeech) :rocket: **News**: - Feb.24, 2022: Our new work, NeuralSVB was accepted by ACL-2022 . [Demo Page](https://neuralsvb.github.io). - Dec.01, 2021: DiffSinger was accepted by AAAI-2022. - Sep.29, 2021: Our recent work `PortaSpeech: Portable and High-Quality Generative Text-to-Speech` was accepted by NeurIPS-2021 . - May.06, 2021: We submitted DiffSinger to Arxiv . ## Environments 1.
