Italian Speech Emotion Recognition
Irene Mantegazza, Stavros Ntalampiras · 2023
Affective computing is gaining increased interest by the scientific community in the last decades with the acoustic modality playing a central role. This paper presents an extensive computational analysis of emotional speech focusing on the Italian language. More precisely, we propose a novel classification algorithm based on a suitable data augmentation scheme. The aim is to classify the seven emotions (anger, disgust, fear, joy, neutral, sadness, and surprise) included in the only publicly available database of Italian emotional speech, i.e. EMOVO. To this end, we employed two feature sets, Mel Frequency Cepstral Coefficients and log-Mel spectrogram, each one combined with a suitable classifier, i.e. Mutilayer perceptron and Convolutional neural network respectively. The implementation and evaluation of the proposed SER pipeline can be accessed through the following link: https://github.com/irenemante/ser_emovo
