摘要
目前,藏语语音参数提取相关研究相对较少,藏语语音处理过程中的重要环节是对藏语语音中的参数提取,其准确性直接影响到系统的性能。语音信号的特征参数主要指的是语音信号的基音频率和共振峰频率。基于MATLAB GUI创建一个平台将语音信号提取、预处理、分窗加帧可提高系统辨认度,让其准确性增加从而更好地提高系统的性能。
At present, there are relatively few researches on the extraction of Tibetan speech parameters, and the extraction of Ti- betan speech parameters is an important part in the process of Tibetan speech processing, and its accuracy directly affects the performance of the system. The characteristic parameters of speech signal are the pitch frequency and formant frequency. Based on the MATLAB GUI to create a platform to voice signal extraction, pretreatment, window frame can increase the system identification, so that the accuracy of the system to improve the performance of the better.
