+LibriTTS-R ([paper](https://arxiv.org/abs/2305.18802)) is a sound quality improved version of the [LibriTTS corpus](http://www.openslr.org/60/) which is a multi-speaker English corpus of approximately 585 hours of read English speech at 24kHz sampling rate, published in 2019. The constituent samples of LibriTTS-R are identical to those of LibriTTS, with only the sound quality improved. To improve sound quality, a speech restoration model, [Miipher proposed by Yuma Koizumi](https://arxiv.org/abs/2303.01664), was used.
+For more information, refer to the paper. If you use the LibriTTS-R corpus in your work, please cite the dataset paper where it was introduced.

+Audio samples of the ground-truth and TTS generated samples are available at the demo page: https://google.github.io/df-conformer/librittsr/
