Title:
SPEAKER ADAPTATION DEVICE AND VOICE RECOGNITION DEVICE
Document Type and Number:
Japanese Patent JP3412496
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To actualize a speaker adaptation system by a data reduction standard pattern selecting method.
SOLUTION: User speaker dependence conversion coefficient selection and arithmetic means 4 and 5 calculate user speaker dependence conversion coefficients by using a reference speaker dependence conversion coefficients for selecting more than one set of reference speaker dependence conversion coefficients by reference speaker dependency conversion coefficient arithmetic and storage means 2 and 3 for arithmetic and storage using a reference speaker voice data feature vector 102 and an initial standard pattern 103 for a feature vector time series by a voice feature quantity extracting means 1 analyzing and extracting sound feature quantities of a user speaker's voice 102. A user speaker dependency standard pattern arithmetic means 6 performs parameter conversion of an initial standard pattern 103 by using the user speaker dependency conversion coefficient and outputs the result as a user speaker dependency standard pattern 104.
