Abstract

In this recent advancement, extraction and identification of human emotions plays a crucial role in developing interpersonal relationship between human and machine. Emotion recognition system are now been adopted in TV industries for training purposes of the performers to improve their acting skills for connecting the audiences. Accordingly, research is been carried out to study the effect of the emotional behaviour of human using various modalities independently. In this research work, a MELD database is been used which is a conversational-based repository originated from a ‘Friends’ TV series. Here, two independent unimodal networks are implemented using the text and audio modalities and their accuracy and performances are relatively compared for any differences. Accordingly, for text unimodal a Bi-LSTM model is observed to be the efficient model with an accuracy of 75% while a LSTM model is seen to be the superior model for audio modality with its highest accuracy of 47%.
