Abstract

Emotion plays a central role in human-to-human interaction, conveying sentiments through body language and voice tone. Such communication is especially important for speech- and hearing-impaired individuals, making the understanding of emotional systems essential in smart communication devices. With advances in artificial intelligence and deep learning, the field has moved away from hand-crafted feature systems toward more complex, data-driven approaches. The use of convolutional, recurrent, and transformer-based architectures has improved both accuracy and reliability of emotion recognition systems. This paper reviews the different methodologies used to analyse facial expressions and hand gestures for emotion recognition, with emphasis on systems being developed to support mute and deaf individuals. The review surveys recent datasets, models, and fusion strategies, and discusses how continued progress in this area can make communication devices more effective and inclusive for the mute and deaf community.
