I. Introduction
Wearable computing is the study or practise of designing, creating, building, and using body-worn computational and sensory devices that allow a new kind of human-computer interaction via the use of an always-on, body-attached component, such as a watch. As the number of people who use wearable computing devices continues to rise year after year, the number of applications for these devices is expanding at an alarming rate. They have an effect on the medical, fitness, ageing, and disability sectors, as well as on education, transportation, finance, gaming, and music businesses. Speech analytics and facial expressions are used in conjunction with one another to identify emotions in a person. However, due to the fact that people attempt to screen their expressions, relying only on speech or facial expression data may not be adequate to correctly determine emotions.
