Speech emotion recognition for affective computing – Complete Phd and Masters Thesis

[ad_1]

Introduction

Speech emotion recognition is a crucial aspect of affective computing, which focuses on developing systems and technologies that can understand, interpret, and respond to human emotions. Emotions play a vital role in human communication, influencing our decisions, behaviors, and social interactions. The ability to recognize and interpret emotions from speech can have various applications, including human-computer interaction, mental health assessment, and customer feedback analysis.

This thesis aims to investigate the development of a system for speech emotion recognition for affective computing. The research will explore the use of machine learning algorithms and signal processing techniques to analyze and classify emotions from speech signals. By understanding the emotional content of speech, the system can provide valuable insights and enhance the quality of human-computer interaction.
