| 摘 要： | 根据不同人发相同音节时,一个基音周期内的波形具有一定相似性的特点,提出一种新的基音周期标准化的语音信号预处理方法。该方法在一个嵌入式的、非特定人、孤立数字的语音识别系统中进行了验证,实验结果表明基音周期标准化能有效提高语音识别的准确率。

| Abstract: | Based on the similarity of the sound wave in a pitch period when different speakers articulate the same syllables,a new pre-process method of speech signal,normalization of pitch period has been proposed in this paper.The new pre-process method has been applied in an embedded speech recognition system designed for speaker-independent isolated digitals recognition.The experiment proves that the use of normalization of pitch period can obviously increase the accuracy of the recognition rate. |
