Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes a weight estimation method for automatic speaker verification (ASV) using score fusion in noisy reverberant environment.
It is well known that background noise and reverberation affect the performances of ASV systems.
Various techniques have been reported to improve robustness against these background noise and reverberation, and score fusion is one of the effective methods.
However, the score fusion requires an adequate weight estimation method.
The proposed method estimates an adequate weight in noisy reverberant environment by using a supervised adaptation with some SNR models.
The QUT-NOISE-SRE protocol is used for simulating the reverberation of the clean speech in the experiments.
The experimental results show that the proposed weight estimation method provides a high performance in noisy reverberant environment.
