ABSTRACT
Integration is defined as a process in which perceptual recognition of a bimodal speech event is influenced by both the auditory and visual sources of information. The exact nature of the information and how the two sources are integrated are questions that are relevant once integration is established. The outcome of our first contrast discussed in Chapter 2 indicates that both auditory and visual sources of information are utilized in speech perception. Given this conclusion, the answer to the next question might seem obvious to some because it is only natural to believe that the two contributing sources must be integrated. This belief might be false, however, and demonstrating that two sources are integrated in perceptual recognition is no easy matter.
