This paper proposes a noise-robust speaker verification method augmented by fundamental frequency (F0).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 F0 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.
