    Title: 使用零值音框嵌入法之語音增強技術
    Authors: 陸清達;Lu, Ching-Ta

    Abstract: 在語音增強或雜訊消除的研究中，雜訊的估計量，會直接影響語音增強系統的效能，因此，本文提出零值音框嵌入法(frame-zero-padding)，藉由在零值音框嵌入處估測雜訊頻譜，達到提升雜訊估計準確度的目標；然後利用該雜訊頻譜估計值，代入通用型頻譜刪減演算法(spectral-subtraction)從事雜訊消除處理，達到語音增強的目標。實驗結果證明：本研究所提的方法，可以準確的估計在單通道裡變化快速的噪音頻譜，處理後語音的清晰度，讓接收端可以更清楚的了解發送端所傳送的訊息。
