Abstract(in Japanese) (See Japanese page)
Abstract(in English) We recorded Japanese read-speech corpus with text obtained from newspapers for studies of large vocabulary speaker-independent continuous speech recognition. A word-frequency list (WFL) was formed from 6.8M sentences from about 5 years of newspaper articles and this yielded a list of 600K words. We selected three sets of recorded texts according no vocabulary sizes: top 7K, 30K, and 150K words of the WFL. We recorded 5,400 utterances by 54 speakers. We also developed a large-vocabulary continuous speech recognition system using context-dependent phoneme HMMs and a bigram grammar and we evaluated the system using this corpus.
