  • Abstract Speech communication plays an important role for human beings. Human speech is not only involving the syntax but also the feeling at the moment. In this thesis we use 11 kinds of speech features, including formant, shimmer, jitter, Linear Predictive Coefficients (LPC), Linear Prediction Cepstral Coefficients (LPCC), Mel-Frequency Cepstral Coefficients (MFCC), first derivative of MFCC (D-MFCC), second derivative of MFCC (DD-MFCC), Log Frequency Power Coefficients (LFPC), Perceptual Linear Prediction (PLP) and RelAtive SpecTrAl PLP (RastaPLP) as the features for emotion classification. These features are usually used in the speech recognition. We try to find the relation between emotion and these features. The methods that we analyze the features are called sequential forward selection (SFS) and sequential backward selection (SBS). Under the KNN classifier, 32 features was chosen, and we get a recognition rate of 84% using our emotion corpus database. We also use the weighted KNN and WDKNN classification method to classify the emotion in the speech. We compare the performance of SVM with respect to weighted KNN and WDKNN. These 32 features are the most appropriate features in the emotion recognition and are used in the continuous speech emotion recognition system.
