ABSTRACT:
A speech dialogues system comprises a voice analyzing portion converting a voice input signal into a time series feature vector, a voice detecting portion detecting the leading end and the trailing end of a voice period in the voice input signal on the basis of the time series feature vector, a recognition and understanding portion translating the time series feature vector into a meaning expression per each voice period, an input dividing portion dividing the meaning expression string into partial strings respectively aggregated in meaning and outputting each partial strings, and an application executing portion for performing corresponding application process for each partial string of the meaning expressions.
