Abstract

Speech is one of the natural ways of expressing ourselves as humans. It is defined as the ability to convey thoughts, ideas, or other information by means of articulating sound into meaningful words. In computer technology, speech processing paved the way for an infinite number of innovations such as Siri,Alexa, etc., which are artificial intelligence systems that are embedded in mobile devices that recognize and respond to human commands. Speech emotion can be perceived with the message of utterance and independent language of utterance. Speech emotion recognition systems are the collection of methodologies that process and classify speech signals to detect human emotions. Speech emotion recognition systems use speech signals labeled with emotions as a dataset. In this proposed system, supervised deep learning techniques such as Long Short Term Memory (LSTM) and Bidirectional LSTM models are used as classifiers to classify emotions. The emotions that are considered for classification are angry, neutral, sad, and excited. Speech emotion recognition has its applications in robotics, call centers, etc
