Emotion Recognition in Speech
Emotion recognition within speech processing, aiming to determine a speaker’s emotional state based on acoustic characteristics of their voice.
Emotion recognition is a task within speech processing that identifies the emotional state of a speaker by analyzing acoustic features of their voice. This technology has broad applications ranging from call centers and healthcare to education and entertainment.
The process utilizes prosodic features (tone, pace, volume) alongside acoustic characteristics to detect emotions. Advances in deep learning have significantly improved the accuracy of emotion recognition, enabling it to identify complex emotional states.
