This repo is a collection of Speech Corpus for automatic speech recognition (ASR) and text-to-speech (TTS).

1. VCTK
   Around 10.4GB. Alternative Host

2. LibriSpeech
   Large-scale (1000 hours) corpus of read English speech.

3. TEDLIUM release 2
   The TED-LIUM corpus was made from audio talks and their transcriptions available on the TED website. The authors have prepared and filtered these data in order to train acoustic models to participate to the International Workshop on Spoken Language Translation 2011 (the LIUM English/French SLT system reached the first rank in the SLT task).

1. CMU ARCTIC Databases
   The databases consist of around 1150 utterances, including US English male (bdl) and female (slt) speakers, as well as other accented speakers.

2. The World English Bible
   The World English Bible is a public domain update of the American Standard Version of 1901 into modern English. Its text and audio recordings are freely avaiable here. Unfortunately, however, each of the audio files matches a chapter, not a verse, so is too long in most cases. Kyubyong sliced them by verse manually. You can get them on his dropbox.

3. Nancy Corpus
   The Nancy corpus from the 2011 Blizzard Challenge. The data is freely availiable for research use on the signing of a license.

1. The NSynth Dataset
   NSynth is an audio dataset containing 305,979 musical notes, each with a unique pitch, timbre, and envelope. For 1,006 instruments from commercial sample libraries, we generated four second, monophonic 16kHz audio snippets, referred to as notes, by ranging over every pitch of a standard MIDI pian o (21-108) as well as five different velocities (25, 50, 75, 100, 127). The note was held for the first three seconds and allowed to decay for the final second.
