Abstract
A reference pattern generating apparatus comprises an initial reference pattern generating unit for dividing a time series of feature vectors obtained from a voice signal into a sequence of small sections in such a manner that any two adjacent small sections overlap each other, and for averaging part of the time series of feature vectors included in each of the plurality of small sections so as to generate an initial reference pattern having a plurality of states respectively associated with the plurality of small sections. A reference pattern generating unit brings each of the plurality of states of the initial reference pattern into correspondence with part of the time series of feature vectors using pattern matching, and then averages the part of the time series of feature vectors brought into correspondence with each of the plurality of states of the initial reference pattern so as to update the initial reference pattern to generate a reference pattern.
