[VoxAngeles Corpus](https://github.com/pacscilab/voxangeles) is a corpus of audited phonetic transcriptions, phone-level alignments and phonetic measurements of the
[UCLA Phonetics Lab Archive](http://archive.phonetics.ucla.edu/), containing data from 95 languages.

We only provide paired speech and phonetic transcription here, while `id[:3]` is the ISO-639-3 language code of the utterance.

This dataset is included as `pr-vox` in our phone recognition benchmarking toolkit, [💎PRiSM](https://github.com/changelinglab/prism).
