| 摘 要： | 首先设计了适用于骨导语音增强的语料采集方案,采集了1 320句涵盖音节全面的语料,并制定了相应的录音规范;其次介绍了骨导语音库建立的意义,说明了语音库建立的实施方案,建成了由40个说话人录制的包括气导语音和骨导语音各8 000句的语音库;然后在对比骨导语音与气导语音声学特性的基础上,分析了骨气导语音在高频和低频的互信息量,为骨导语音的增强提供了理论依据;最后基于现阶段的研究及文中构建的语音库对今后的研究做出展望。

| Abstract: | In this paper, a corpus acquisition scheme suitable for bone-conducted speech enhancement is designed, total 1 320 syllabic balanced sentences of covering comprehensive syllables are collected and a corresponding recording specification is developed. The significance of establishing bone-conducted speech database and the implementation scheme of the database are introduced, and a database containing 8 000 air-conducted and bone-conduced speeches spoken by 40 speakers is constructed. Based on the comparison of acoustic characteristics between air-conducted and bone-conducted speeches, the mutual information contents between bone and air conducted speeches at high and low frequencies are analyzed, which provides a theoretical basis for the enhancement of bone-conducted speech. Finally, based on the current stage of research and combining the database constructed in this paper, the future research direction is prospected. |
