Abstract

We argue here that examination of the stimulus source is a prerequisite to understanding how audiovisual (AV) stimuli are processed perceptually. This is based on mounting evidence that the act of speech production generates multimodal events whose audible and visible components are highly correlated with each other and the vocal tract source. How this multimodal structuring is exploited perceptually, or not, needs to be demonstrated by conducting studies that take the properties of the stimulus source into account.
