接下來我們提出了一種混合式的切音方法，就是將原本已經應用的熵(entropy)跟過零率 (zero-crossing rate)做結合，在有雜訊的條件下，找出真正的有要與音片段；而在這有效語音的片斷下，我們也同時再加上使用過零率(zero-crossing rate)來找出語音中的氣音部分。使用此混合式切音法將可有效的改善基於特定文字語音驗證系統的效能。
Speaker verification has been used in the area of biometric authentication. The recognition rate is the key issue for recent development of speech recognition. In this thesis, instead of the traditional endpoint detection method, we have developed a new mixture endpoint detection method to increase the recognition rate of the speaker verification. We adopt entropy and zero-crossing for end point detection to detect a real speech sections. We use this technique to locate a real speech section in noisy data, and then use the zero-crossing to detect an air sound from the speech. After these processes, the SNR can really reflect the real speech level; therefore the threshold can be set. Using the mixture endpoint detection technique can easily increase the text-dependent speaker verification system efficiency.
