Speech Emotion Recognition using Support Vector Machine
This is an incremental improvement for speech processing applications, focusing on emotion classification.
The paper tackled speech emotion recognition by classifying four emotions using Support Vector Machine with two strategies, achieving results through comparative analysis of features like MFCC and LPCC.
In this project, we aim to classify the speech taken as one of the four emotions namely, sadness, anger, fear and happiness. The samples that have been taken to complete this project are taken from Linguistic Data Consortium (LDC) and UGA database. The important characteristics determined from the samples are energy, pitch, MFCC coefficients, LPCC coefficients and speaker rate. The classifier used to classify these emotional states is Support Vector Machine (SVM) and this is done using two classification strategies: One against All (OAA) and Gender Dependent Classification. Furthermore, a comparative analysis has been conducted between the two and LPCC and MFCC algorithms as well.
