Abstract

Automatic speech emotion recognition still has to overcome several obstacles before it can be employed in realistic situations. One of these barriers is the lack of suitable training data, both in quantity and quality. The aim of this study is to investigate the effect of cross-corpus data on automatic classification of emotional speech. In this work, features vectors, constituted by the Mel frequency cepstral coefficients (MFCC) extracted from the speech signal are used to train the support vector machines (SVM) and Gaussian mixture models (GMM). The research describes the evaluation of three different emotional databases from three different languages (English, Polish and German) following a three cross-corpus strategies. In the intra-corpus scenario, the accuracies were found to vary widely between 70% and 87%. In the inter-corpus scenario, the obtained average recall is 70.87%. The accuracies of the cross-corpus scenario were found to be below to 50%.
