In many cases research in the fields of audiovisual speech analysis, synthesis, perception and (automatic) recognition is carried out separately with only limited account for the neighboring areas. But the author claims that these neighboring areas yield huge, currently idle potential to improve and better understand the field under investigation and that human speech as a phenomenon should be looked at from a more holistic point of view. This paper briefly looks into the fields of audiovisual speech research and tries to identify existing links between them as well as future collaboration for promising prospective mutual benefit.
