Noise-Robust Speaker Verification Using F 0 Features

Abstract

This paper proposes a noise-robust speaker verification method augmented by fundamental frequency (F 0 ). The paper first describes a noise-robust F0 extraction method using the Hough transform. Then, it proposes a robust speaker verification method using multi-stream HMMs which fuse the extracted F 0 and cepstral features. Experiments are conducted using fourconnected -digit utterances of Japanese by 37 male speakers recorded at five sessions over a half year period. The utterances are contaminated with white noise at various SNR levels. Experimental results show that the F0 features improve the verification performance in all SNR conditions
