Emotion recognition by speech signals

  title={Emotion recognition by speech signals},
  author={Oh-Wook Kwon and Kwokleung Chan and Jiucang Hao and Te-Won Lee},
For emotion recognition, we selected pitch, log energy, formant, mel-band energies, and mel frequency cepstral coefficients (MFCCs) as the base features, and added velocity/acceleration of pitch and MFCCs to form feature streams. We extracted statistics used for discriminative classifiers, assuming that each stream is a one-dimensional signal. Extracted features were analyzed by using quadratic discriminant analysis (QDA) and support vector machine (SVM). Experimental results showed that pitch… CONTINUE READING
