摘要：The objective of this work is the comparative study of the speech signal between the silence and non- silenceregions of the speech signal. In this work our main goal is to observe the pitch contour, energy and duration aretime-varying and also study how these changes play an important role in emotion recognition. An important stepin emotion recognition from speech is to select significant features which carry large emotional informationabout the speech signal. It was given that emotion recognition from speech has different types of features,among them is prosody, spectral and acoustic features. Sometimes prosody features are called supra-segmentalfeatures. It deals with the auditory qualities of the sound and it can also reflect aspects of meaning, intention andemotional state of the characters [1] [2].Prosody Feature consists of more pitch information which is used inidentifying the emotion such as Pitch, Energy, and Duration. In this work we also explored the importance of thespeech signal which doesn’t have silence regions and how the signal varies due to of pitch contour, energy,duration values, to analyze their contribution towards the recognition of emotion. The main intention of thiswork was to utilize the speech properly by means of actual speech content, i.e., with no other silence parts orunnecessary parts of the signal.
