| Title: | JOINT ACOUSTIC-MODULATION FREQUENCY FOR SPEAKER RECOGNITION | ||
| Authors: | Tomi Kinnunen, Institute for Infocomm Research, Singapore | ||
| Abstract: | We propose a method for computing joint acoustic-modulation frequency feature for speaker recognition. This feature describes the amplitude modulation spectrum of each subband, and results in a single feature vector per utterance. This vector is directly used as the speaker's modulation frequency template, excluding the need for a separate training phase. The effects of analysis parameters and pattern matching are studied using the NIST 2001 corpus. When fusing the proposed feature with the baseline MFCC/GMM system, EER is reduced from 18.2 % to 16.7 %. | ||
