| Abstract(in English) | This paper proposes an automatic stream-weight optimization method for speaker verification using multi-stream HMMs. We have already proposed a noise-robust speaker verification method using multi-stream HMMs for integrating spectral and prosodic information. The paper first shows the effectiveness obtained by using multi-stream technique in our speaker verification framework. Next, a stream-weight adaptation method using both linear discriminant analysis (LDA) and Adaboost is proposed. Experiments were conducted using four-connected-digit utterances of Japanese contaminated by white noise with various SNRs. Experimental results show that 1) the verification performance was improved in all SNR conditions by using stream weights estimated by LDA and 2) the performance is further improved by using Adaboost in 10 - 30dB SNR conditions. |
