Speech Based Emotion Recognition System

Abstract

Emotion reputation from speech alerts is a crucial yet difficult part of human-computer interaction (HCI). Several well-known speech assessment and type processes were employed in the literature on speech emotion reputation (SER) to extract emotions from warnings. Deep learning algorithms have recently been proposed as an alternative to conventional ones for SER. We develop a SER system that is totally based on exclusive classifiers and functions extraction techniques. Features from the speech alerts are utilised to train exclusive classifiers. To identify the broadest feasible appropriate characteristic subset, the feature choice (FS) procedure is performed. A number of device studying paradigms have been employed for the emotion-related task. Seven sentiments are first classified using a Recurrent Neural Network (RNN) classifier. Their outcomes are contrasted with those obtained using techniques such as Support Vector Machines (SVM) and Multivariate Linear Regression (MLR) , which are often employed in the area of spoken audio alert emotion recognition. The experimental statistics set requires the use of the Berlin and Spanish databases. This investigation demonstrates that the classifiers for the Berlin database attain an accuracy of 83% after applying Speaker Normalization (SN) and a characteristic selection to the functions. The RNN classifier for datasets that has no SN and no FS obtains a high accuracy of 94%.
