Speech corpus

This paper introduces a new open-source speech corpus named "speechocean762" designed for pronunciation assessment use, consisting of 5000 English utterances from 250 non-native speakers, where half of the speakers are children.Five experts annotated each of the utterances at sentence-level, wordlevel and phoneme-level.A baseline system is released in open source to illustrate the phoneme-level pronunciation assessment workflow on this corpus.This corpus is allowed to be used freely for commercial and non-commercial purposes.It is available for free download from OpenSLR, and the corresponding baseline system is published in the Kaldi speech recognition toolkit.
