Expression control using synthetic speech.Brian Wyvill (blob@cs.uvic.ca) and David R. Hill (hill@cpsc.ucalgary.ca)Department of Computer Science, University of Calgary.2500 University Drive N.W.Calgary, Alberta, Canada, T2N 1N4AbstractThis tutorial paper presents a practical guide to animating facial expressions synchronised to a rule based speech synthesiser. A description of speech synthesis by rules is given and how a set of parameters which drive both the speech synthesis and the graphics is derived. An example animation is described along with the outstanding problems.Key words: Computer Graphics, Animation, Speech Synthesis, Face-Animation.© ACM, 1989. This is the authors’ version of the work.

DOI unknown.Note (drh 2008): Appendix A was added, after publication of these tutorial notes by the ACM, to flesh out some details of the parameter synthesis, and to provide a more complete acoustic parameter table (the original garbled table headings have been corrected in the original paper text that follows, but the data was still incomplete—intended for discussion in a tutorial).Fairly soon after the animation work using the formant synthesiser was finished a completely new articulatory speech synthesis system was developed by ...
