Different researchers have been introduced many systems to identify the emotion from human speech. This paper will give an idea about different techniques and working procedure of speech emotion recognition system. Also it gives the brief idea about the emotional speech dataset. We have reconsidered some earlier implemented speech emotion recognition technologies which use various feature extraction method and classifier for emotion recognition. Different types of classifier performance are also discussed for speech emotion recognition.
