LibriTTS

LibriTTS is a multi-speaker English corpus of approximately 585 hours of read English speech at 24kHz sampling rate. The LibriTTS corpus is designed for TTS research. It is derived from the original materials (mp3 audio files from LibriVox and text files from Project Gutenberg) of the LibriSpeech corpus.

The main differences from the LibriSpeech corpus are listed below:

1. The audio files are at 24kHz sampling rate.
2. The speech is split at sentence breaks.
3. Both original and normalized texts are included.
4. Contextual information (e.g., neighbouring sentences) can be extracted.
5. Utterances with significant background noise are excluded.
