OC16-CE80: A Chinese-English Mixlingual Database and A Speech Recognition Baseline
TABLE I: OC16-CE80 Data Profile
['[BOLD] Database', 'Language', 'Channel', 'Utterances/Speaker']
The OC16-CE80 database was originally created by SpeechOcean, targeting for various mixlingual speech processing tasks (mainly ASR). The entire database involves about 80 hours of speech signals, which were recorded by mobile phones in reading style, with a sampling rate of 16 kHz and a sample size of 16 bits. The text of the utterances was selected from a large text corpus, following a greedy search strategy that chose the sentence that can improve the phone coverage mostly one by one. The entire database was separated into a training set, a development set and a test set.
