就语音信号的清浊音判决方法提出了一种新的自适应预铡判决的方法.该方法立足于语音信号的非平稳特性,采用了递推最小二乘法(RLS),从传统的短时分析出发,结合预测的方法对语音信号进行自适应预测,设定目标函数,以非线性处理的方法实现了对非平稳的语音信号的清浊音判决;并将该方法与传统的清浊音判决法相比较并进行了仿真研究,结果表明文中提出的新方法能较好地进行清浊音判决.
就語音信號的清濁音判決方法提齣瞭一種新的自適應預鍘判決的方法.該方法立足于語音信號的非平穩特性,採用瞭遞推最小二乘法(RLS),從傳統的短時分析齣髮,結閤預測的方法對語音信號進行自適應預測,設定目標函數,以非線性處理的方法實現瞭對非平穩的語音信號的清濁音判決;併將該方法與傳統的清濁音判決法相比較併進行瞭倣真研究,結果錶明文中提齣的新方法能較好地進行清濁音判決.

This paper presents a new method of voicing judgment the automatic predictive determination which is established based upon the nonlinear characteristic, using the Reeursive least square (RLS) combined with predictive way to predict the speech signal. A goal function is set and the expectant result is achieved. The new method is simulated by MATLAB software and is compared with the traditional one. The result of this indicates that the new one will perform the voicing determination better.
