Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents a voice conversion based on NMF for noisy environments.
We prepared parallel exemplars that consist of the source and target exemplars, which have the same texts uttered by the source and target speakers.
The input source signal is decomposed into the source exemplars, noise exemplars obtained from the input signal, and their weights.
Then, the converted signal is obtained by calculating the linear
combination of the target exemplars and the weights which are
calculated using the source exemplars.
In the proposed method, segment features are used for the
voice conversion technique based on NMFin order to improve the accuracy
of the weight estimation.
The effectiveness of this method was confirmed by comparing its effectiveness with that of a conventional method.
