VOICE RECOGNITION SYSTEM, VOICE RECOGNITION METHOD, AND VOICE RECOGNITION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a voice recognition system that satisfactorily removes influence of environmental noise on the premise of asynchronous observation or intermittent observation by a microphone.SOLUTION: A voice recognition system comprises: a noise model storage unit for storing a plurality of noise models generated by using a result of asynchronous observation and/or intermittent observation of one or more microphones; and a noise rejection voice recognition processing unit that acquires a sound signal (analyzed sound) of a voice section to be a voice recognition object to perform generation processing of a plurality of virtual noise rejection sound signals in which noise influence obtained from each noise model included in a plurality of noise models is reduced from the sound signal of the voice section, and that sends each of the plurality of virtual noise rejection sound signals to voice recognition processing to perform derivation processing of voice information included in the voice section to be the voice recognition object while inputting each of the recognition result.
