| 摘 要： | 提出了一种可以用于情绪识别的语音基音周期分析方法,利用平均短时能量和平均短时过零率结合进行语音端点的检测,通过自相关函数计算出浊音帧的基音周期。这种方法可以准确的分辨出男女声音,结合人在不同情绪下的发音特点可以进一步分辨出人的不同情绪。该方法简单易行,运算方便,为语音情绪识别提供了很好的研究手段。

| Abstract: | In this paper,a method is proposed to calculate pitch period which is used for emotional recognition.Speech signal endpoints-detection is presented by means of combining with the average short-term energy and average short-term zero-crossing rate,and then the pitch period of voiced frame is calculated by autocorrelation function.In this way,male and female voices can be distinguished accurately,and people's different moods can be identified combined with pronunciation characteristics.This method is simple a... |
