Description: 本设计采用了一种基于三参数组合的方法对语音信号进行了清/浊音判决。在传统两参数（短时能量和过零率）算法基础上增加了自相关函数作为判决参数，减少了清/浊音信号误判率。-This design uses a combination of methods based on three parameters of the voice signals of the Qing/voiced sentence. In the traditional two parameters (short-term energy and zero crossing rate) algorithm based on the increase since the correlation function as a decision parameter, reducing the clearance/voiced signal false positives.

Description: 这是一个matlab程序，该程序的功能是读取一个 .wav 格式的语音信号，画出该语音信号的短时能量。主程序调用了自己编写的两个函数，函数的功能分别是对语音信号进行分帧以及计算每一帧的时间。语音分帧是语音信号处理的关键步骤，该程序可以帮助你快速入门。-This is a matlab program, the function of the program is to read a ' .wav' voice signal format, draw short-term energy of the speech signal. The main program calls two functions I have written, performance function are calculated for each sub-frame and the time frame of the speech signal. Voice Framing is a key step in the speech signal processing, the program can help you get started quickly. Platform: |
