LibriSpeech IPA Phoneme Labels

This repository provides IPA-based phoneme annotations and lexicon for the LibriSpeech dataset.

All phoneme labels are converted from CMU Pronouncing Dictionary (CMU-Dict) phonemes into IPA symbols using deterministic rules, with the help of the following toolkit:

https://pypi.org/project/pinyin-to-ipa

The data is intended for phoneme-based ASR, P2G/G2P research, phoneme CTC / AED models, and cross-lingual phoneme experiments.
