Prosodiag - Prosodic Segmentation and Structuring of Dialogue (HSFR + NUTEK) 1993 –1996
Gösta Bruce, Björn Granström, Kjell Gustafson, David House, Paul Touati
The object of study is the prosody of dialogue in a language technology framework. The primary goal of the project is to increase our understanding of how prosodic aspects of speech are exploited interactively in dialogue and on the basis of this increased knowledge to be able to create a more powerful prosody model.

MPEG-4 Facial Animation Parameter (FAP) A subset of 31 FAPs out of the 68 FAPs defined in the MPEG-4 standard, including only the ones that we were able to calculate directly from our measured point data
Focal Motion Quotient, FMQ, defined as the standard deviation of a FAP parameter taken over a word in focal position, divided by the average standard deviation of the same FAP in the same word in non-focal position.
The focal motion quotient, FMQ, averaged across all sentences, for all measured MPEG-4 FAPs for several expressive modes
