- separate emotion process to sub emotions
- available databases:
- database collection:
- acted : GEneva multimodeal emotion portrayals (GEMEP)
- induced : eNTERFACE'05 EMOTION Database
- spontaneous: SEMAINE, AFEW
- others: RML,VAM ,FAU AUBO,SAVEE,TUMAVIC,IEMOCAP,SEMAINE MHMC
- static vs dynamic modeling
STATIC:
- low level descriptors (LLDs) and functionals
- good for discriminate high and low-arousal emotions
- temporal information is lost, no suitable for long utterances, can not detect change in emotion
DYNAMIC:
- frame as the basis, LLDs are extracted and modeled by GMMs, HMMs, DTW
- temporal information is obtained
- difficult to model context well
- a large number of local features need to be extracted
- Unit choice for dynamic modeling
- technical unit: frame, time slice, equally-divided unit
- meaningful unit: word, syllable, phrases
- emotionally consistent unit: emotion profiles, emotograms
