METHOD, DEVICE, AND PROGRAM FOR VOICE RECOGNITION

摘要

PROBLEM TO BE SOLVED: To provide a method and device for voice recognition for recognizing the voice of a speaker other than a leaner of HMM with high precision. SOLUTION: In the voice recognition using an HMM having a mixed multidimensional regular distribution, equal output probability is used for input feature vectors within a specific distance range having its center at the mean vector of the mixed multidimensional regular distribution to prevent the recognition precision of an acoustically different speaker from becoming worse deviating from a range of speech prepared as learning data.
