Machine learning approach for emotional speech classification

Abstract

Recognition of Emotion from speech is an extremely challenging task in current research. Using the reduced dimension method for feature extraction, Singular Value Decomposition (SVD) has proposed. Classification using Support Vector Machines (SVM) with SVD features shows an excellent result, which is the novelty of this work. The proposed features are evaluated for the task of emotion classification using simulation method. SVM has been designed as the classifier for classifying the unseen emotions in speech. It is shown that the classifier with such features outperforms the methods substantially. Using such features for classification outperforms the accuracy level approximately 90% that leads towards automatic recognition.
