Abstract

A prototype of a Japanese text dictation system has been developed. It is composed of an acoustic processor, a Bunsetsu-unit spotting processor, and a syntactic processor with semantic constraints. The acoustic processor is constructed using the modified LVQ2 method. The modified LVQ2 method achieves a high phoneme recognition performance of 86.1%. The syntax driven continuous DP matching algorithm is used for spotting Bunsetsu-units. This method greatly reduces the amount of computation and the storage capacity necessary for spotting the Bunsetsu units. Analysis of the dependency structure among the Bunsetsu-unit candidates is effectively carried out using the syntactic and semantic information.
