Emotion recognition in human-computer interaction - Cowie 2001

One channel broadcasts explicit communications about anything; the other conveys implicit messages about the speakers. Linguistics and technology have made great strides in comprehending the first, explicit channel. Second, implicit channel tasks include understanding the other party's feelings. Signal processing and analysis mechanisms must be developed as psychological and linguistic analyses of emotion are consolidated. This page covers those topics. It's inspired by the PKYSTA project, which aims to construct a hybrid system that can discern emotions from faces and voices.
