This dissertation is different from traditional speech enhancement methods which are based on noise characteristic such as adaptive noise cancellation or spectral subtraction processing. in this dissertation the speech signal conducted by bone was taken as the object to be studied and the exploitive study on the acoustical characteristic of speech signal conducted by bone was performed by the method of theory combined with experiment. then a proposition about speech reconstruction based on speech signal conducted by bone was presented, and the design of software and hardware was completed
本文與傳統的基於噪聲特性的自適應噪聲抵消法、頻譜減法等語音增強降噪技術不同，是以骨導語言為研究對象，採用理論與實驗相結合的方法對骨導信號的聲學特性進行了探索性研究，進而提出了基於骨導信號的語音重構技術，並完成了相應的軟硬體開發。 -
