| 講演名 | 2008-03-20 15:15 ［ポスター講演］A STUDY ON THE LP-BASED BLIND MODEL IN RESTORING BONE-CONDUCTED SPEECH ○Thang tat Vu・Masashi Unoki・Masato Akagi（JAIST）  SP2007-189 |

| 抄録 | （和） | Due to the stability against the external noise, bone-conducted (BC) speech seems better to be used instead of noisy air-conducted speech in an extremely noisy environment. However the quality of BC speech is very low and restoring quality and intelligibility of BC speech is a challenged topic in speech signal processing field. As the main issue to improve the BC speech, many studies try to model and resolve the degradation when the signal is conducted through bone transduction. In previous study, we proposed a linear prediction (LP) based blind-restoration model. In this paper, we therefore completely evaluated the proposed model in comparison with other models to find out whether our proposed model could adequately improve voice quality and the intelligibility of BC speech, using objective measures (LSD, MCD, and LCD) and carrying out intelligibility tests for Japanese (JWITs), Vietnamese (VWIT) and Modified Rhyme Tests (MRTs) for English. The experimental results on different language, i.e. Japanese, English and Vietnamese proved the practicability of our blind-BC restoration method. |
