AI Matches Humans in Detecting Emotions from Voice
- New study shows AI can detect emotions from short audio clips with accuracy on par with humans
- Quality training data critical; clipped audio from 1500+ recordings of 6 emotions joy, fear, neutral, anger, sadness, disgust
- AI models tested deep neural network (DNN), convolutional neural network (CNN), and a DNN+CNN hybrid
- Psychoacoustic features analyzed included pitch, amplitude, spectral properties, MFCC, chroma, Tonnetz
- Combination of AI & psychoacoustics shows machines can demonstrate cognitive empathy via voice on human level
