... module and to simulate bimodal and multimodal emotion recognition, we used four kinds of emotions or musical moods in each experiment: neutral, happy, angry, and sad. We chose ‘angry’ and ‘sad’ ... emotions facially and vocally. Thus, there are few standard multimodal databases collected from people around the world. Instead, most research studies depend on facial images and s...
