Acoustic Modeling for Emotion Recognition by Koteswara Rao Anne, Swarna Kuchibhotla, Hima Deepthi

By Koteswara Rao Anne, Swarna Kuchibhotla, Hima Deepthi Vankayalapati

This e-book provides country of artwork study in speech emotion reputation. Readers are first provided with easy study and purposes – progressively extra strengthen info is equipped, giving readers finished tips for classify feelings via speech. Simulated databases are used and effects largely in comparison, with the gains and the algorithms applied utilizing MATLAB. a number of emotion reputation versions like Linear Discriminant research (LDA), Regularized Discriminant research (RDA), help Vector Machines (SVM) and K-Nearest neighbor (KNN) and are explored intimately utilizing prosody and spectral positive factors, and have fusion options.

A comparative analysis is done elaborately for all these classifiers as well as for databases. 2 Emotions Used in This Work In order to validate the results of different classifiers on happy, neutral, anger and sad emotional classes, recognition tests were carried out in two phases like baseline results and feature fusion results. 1. It seems that spectral features provide higher recognition accuracies than prosody ones. According to these results, it is observed that even though prosody parameters show very low class separability it does not perform so badly.

In this thesis work, we used Euclidean distance, which is able to compute the distance between different matrices. 1 Introduction In this work the emotion recognition performance is determined by each classifier LDA, RDA, SVM and KNN for each database. A comparative analysis is done elaborately for all these classifiers as well as for databases. 2 Emotions Used in This Work In order to validate the results of different classifiers on happy, neutral, anger and sad emotional classes, recognition tests were carried out in two phases like baseline results and feature fusion results.

2 shows the fusion at decision level. For decision level fusion, we can use either multiple samples for the same type of sensors or multiple sample from different types of sensors [56]. Here multiple samples from the same type of sensor information namely acoustic features are processed independently and finally the decisions of the appropriate classifiers are fused as shown in Fig. 2 Multi Modal Feature Fusion 31 c1 c2 f9 f10 f11 f12 f13 f14 f15 f16 1 1 1 1 1 1 1 1 1 1 0 1 0 0 0 0 1 1 1 1 1 0 0 0 1 1 0 0 1 1 1 1 0 1 0 1 0 1 0 1 Fig.
