Abstract(in English) | Bone-conducted (BC) speech can be used instead of air-conducted (AC) speech for speech communication 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 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. However, we have not yet completely evaluated the proposed model, in particular, with regard to speech intelligibility. In this paer, we therefore completely evaluated the proposed model in comparison with other models to find out whether the model could adequately improve voice quality and the intelligibility of BC speech, using objective measures (LSD, MOD, and LCD) and carrying out Japanese-word Intelligibility Tests (JITs) and Modified Rhyme Tests (MRTs) for English word. The experimental resutls of objective and subjective evaluations (JITs and RMTs) proved the practicability of blind-BC restoration. |
