| Research Abstract |
Bilingual automatic speech recognition(ASR), which performs ASRs of each language simultaneously and complementarily, was investigated. The bilingual ASR uses a translation model(TM) and its score adding to acoustic and language model scores which are used in common ASR systems. Therefore, 1) TM modeling, 2) efficient calculation of TM scores. and 3) automatic detection of corresponding utterances in bilingual speech were studied in detail using English-Japanese pair. Suitable TMs and effects and problems of detection of corresponding utterance were shown. We reduced processing time significantly for TM score calculation without significant degradation of bilingual ASR accuracy.
