Abstract(in English) | Accuracy of Large-Vocabulary Continuous Speech Recognition(LVCSR) systems depend not only on the performance of its acoustic models but also on the performance of the language models. We successfully incorporated word trigram language models to a LVCSR system for the first time in Japanese speech recognition. For a 7000-word vocabulary speaker-independent recognition task, trigram language models were trained using texts from a CD-ROM compilation of a Japanese news paper(Nikkei 1990-1994). Evaluation tests show that 44% reduction in word error rate from our previous word bigram system was achieved resulting in 90% word accuracy. |
