Abstract

The interaction between stimulus factors and cognitive factors during multisensory integration of audiovisual speech.

Highlights

The amount of research focused on multisensory speech perception has expanded considerably in recent years
Much of this research has focused on which factors influence whether or not an auditory and a visual speech input are “integrated”; a special case of how our perceptual systems solve the “binding problem” (Treisman, 1996)
The factors that have been identified as influencing multisensory integration can be roughly divided into two groups

Summary

Introduction

First are the low-level stimulus factors that include the physical characteristics of the sensory signals. When auditory and visual speech signals are closely proximate in time (low-level), they are more likely to have originated from the same speaker, and should be integrated (Dixon and Spitz, 1980; Stevenson et al, 2012b).
