中文摘要	在实际应用中,语音情感变化的检测比单纯的语音情感识别具有更广泛的应用前景,而目前关于语音情感变化检测的研究却很少。为了实现语音情感变化检测,本文研究了基于情感分数曲线的检测方法。首先将情感语音划分成一些语音段,采用基于频谱特征的方法进行情感识别,得到情感分数曲线。然后根据情感分数曲线的变化规律,确定发生情感变化的时间范围。针对该方法正确率较低的问题,对其进行了分析和改进,改进后的方法可以达到86.1%的正确率,并且具有比较稳定的检测性能。; For practical application, the emotional variation detection of speech has more extensive applying prospect than sin- gle emotional speech recognition. However, there are only few researches on this subject at present. This paper researches a method based on emotion score curves which achieves the emotional variation detection of speech. Firstly, the raw speech is divided into some segments. Then a method based on spectral features is used to recognize each emotional speech segment and several score curves are obtained. Finally, the time range of emotional variation is detected according to the changing law of score curves. Because of the problem of nonideal detection accuracy, the above method is analyzed further. Experimental results demonstrate that the improved method has the accuracy of 86.1% and its performance is relatively stable.; 国家自然科学基金重点项目(60433030)
