SPEAKER RECOGNIZING DEVICE, PROGRAM, AND SPEAKER RECOGNIZING METHOD

摘要

To realize high-accuracy speaker recognition, a DP matching section (11) determines an optimum matching series (F) which minimizes the sum of phonological distances by using a pitch time series of two characteristic parameter time series (A, B), a speaker-to-speaker distance calculating section determines the sum of the personal distances by using the optimum matching series and the cepstrum coefficient time series of the two characteristic parameter time series (A, B), and an identifying section identifies the speaker on the basis of the sum. Thus, both phonological resolution and speaker resolution are compatible, and stable recognition performance is ensured, thereby realizing high-accuracy speaker recognition.
