Emotion recognition definition
Emotion recognition refers to the ability to detect human emotions from various sources (e.g., facial expressions, tone of voice, and body language). Emotion recognition technology involves the use of machine learning (ML) algorithms and artificial intelligence (AI) to analyze and interpret these signals and determine human emotion.

How emotion recognition technology works
Emotion recognition technology uses a variety of methods to detect and analyze human emotions, such as:
- Facial recognition. This technique analyzes facial expressions to determine a person’s emotional state. Facial recognition uses various algorithms to analyze features such as the position of the eyebrows, the movement of the eyes, and the shape of the mouth to detect and determine emotion.
- Speech analysis. Speech analysis involves analyzing a person's tone, pitch, and intensity to identify their emotional state. Speech analysis algorithms detect voice pattern variations indicating anger, sadness, or excitement.
- Physiological signals. The physiological signal analysis involves analyzing heart rate, skin conductance, and brain activity to determine a person’s emotions. Physiological signals allow emotion recognition technology to provide more accurate and objective results. However, they require specialized equipment and are more difficult to measure.
Emotion recognition use cases
- Marketing. Emotional recognition could improve customer service and personalized marketing.
- Human-robot interactions. Emotion recognition could improve the interactions between humans and robots.
- Healthcare. Emotion recognition technology could improve mental health diagnosis and treatment.
- Education. The technology could help teachers better monitor student engagement, attention, and emotional state.
