Can anyone point me to opensource databases of speech audio with phonemes labelled, .wav or the like + label files, e.g.

# time, phoneme
0.31200 ao
0.41200 th
0.54200 er

I'd prefer English, several speakers, and various noise levels, but let's see what's around.
(There's cmu_*_arctic from CMU festvox; it's pretty old, 2005 — there must be more.)

I am not 100% sure if the following links are useful for you. Please let me know if you are looking for something else.




  • Thanks @Anastasios; I don't see phoneme label files so far, will ask the RSS2015 people. (Pros might consider phoneme labelling trivial / impossible / useless, comments ?)

There is an auxiliary dataset of phoneme labels for the Librispeech corpus. It can be found here Zenodo: LibriSpeech Alignments.
