Abstract (in Japanese) (See Japanese page) 
(in English) Bone-conducted (BC) speech can be used instead of air-conducted (AC) speech for speech communication and speech recognition systems in an extremely noisy environment. However, it has very poor sound quality and its intelligibility is degraded when transmitted through bone conduction. Therefore, blindly improving quality and intelligibility of BC speech is a challenging topic. In previous study, we proposed a linear prediction (LP) based blind-restoration model to improve voice quality and intelligibility of BC speech and we showed usefulness of the proposed method in clean condition. In this paper, as realistic applications, we therefore comprehensively evaluated the proposed model in comparison with other models to find out whether the model could adequately improve the BC speech or not, via Japanese word intelligibility and word recognition tests in both clean and noisy environments. As results, it was found that the method can be available in high noisy environemnts, without Lombard effects.
