摘　　要：随着现代科技和计算机以及平板电脑等的发展,语音交互将成为人机通信的主要方式,而汉语在语音合成中声调是不可或缺的一个重要组成部分。在声调提取过程中首先采用改进的短时自相关函数的方法进行基音检测,同时为了能较为精确地进行浊音的基音检测,利用变长分帧的方法提取基音周期序列,并通过Matlab仿真得到了汉语语音4种声调的调型曲线。仿真结果表明,该方法所得到的调型曲线与汉语普通话声调的典型曲线较为一致。Along with the development of modern technology and computers,as well as tablet PC,voice interaction will become the main form of man-machine communication,and in the speech synthesis of Chinese,tone is an indispensable important component.In the process of tone recognition,firstly,using an improved method of shot-time autocorrelation function for pitch detection,in order to get the pitch period of the voiced sound simultaneously at the same time,we use the method of changed frame to get the pitch period,then get the 4 kinds of tone curve of Chinese speech with Matlab.The results of the simulation show that the curve of the tone obtained by this method is consistent with the typical curve of Mandarin tone.
