情感语音信息中共振峰参数的提取方法

共振峰参数是反映声道特性的一个重要参数，不同情感的发音使声道有不同的变化，所以不同情感发音的共振峰位置不同，首先采用线性预测法求出预测系数，然后用预测系数估计声道的功率谱，再用峰值检出法算出共振峰频率，运用此方法，可以判别出不同情感信息的共振峰频率，从而实现语音的情感识别。

The Method Analysis of Formant Parameters Picked - up in Sensibility Speech Communication

Formant parameters are important parameters in track characteristics. Different sensibility speech can change the track. So the situation of formant parameter of different sensibility speech is different. To prove this, we first use LPC to work-up prediction modulus, then to estimate the power stability of the track, and finally use peak-picking to work-up the frequency of formant. By this method, we can estimate formant's frequency of different sensibility information, and realize sensibility identification of speech.
