This work consists on the automatic recognition of the emotions in the speech, because it plays a very significant role in the communication. The automatic recognition of the emotions potentially had a broad application in the Human Machine Interaction. In this work emotional speech corpus in Algerian Dialect was created for parameters extraction. The selected parameters in our study are the prosodic (pitch, intensity and duration), the unvoiced frames, jitter, shimmer and cepstral parameters MFCCs (Mel-Frequency Cepstral Coefficients) to analyze the emotions of fear and neutral. These parameters will be used in the automatic recognition of the emotions. The system of recognition is based on the methods of classification KNN (K-Nearest Neighbor), SVM (Support Vector Machine) and ANN (Artificial Neural Network). The obtained results lead us to observe that the use of MFCCs parameters gives a very acceptable rate of emotion recognition.
