Speech Emotion Recognition: A Review

Abstract

Research-oriented work in speech recognition has garnered a lot of interest since last two decades. Emotions derived from speech have drawn considerable interest of researchers especially for analysis of human behavior. Emotions from a speech are extracted and identified by classifiers and systems being developed and improved over a period of time. This paper attempts to discuss the process of speech emotion recognition, different methods of pre-processing techniques, feature extraction methods, and classifiers used for speech emotion recognition.
