Multimodal Affect Analysis

An approach that performs stronger affect analysis by combining signals such as audio, text, and sometimes facial expression.

Multimodal affect analysis aims to produce more reliable interpretation when the audio signal alone is insufficient. A vocal cue may suggest one emotion, while the words or facial expression indicate something else. Combining audio, text, and visual signals therefore yields more comprehensive behavior analytics. It is one of the advanced components of interactive AI systems.
