Multisensory Speech in Perception and Production

Many different types of information can be processed across the senses. In particular, speech has received great attention in many fields and disciplines because of its cross-sensory nature. In fact, speech information can be heard, seen, and even felt, and when speech information is available across multiple sensory modalities (e.g., when heard and seen) it can enhance speech perception over unisensory conditions (e.g., when only heard). Such multisensory processing can vary with language experiences (e.g. monolinguals, bilinguals, multilinguals), familiarity with a talker, health, cognitive ability, and age. Each of these aspects may subsequently impact speech production. Underlying the perception and production of speech is a concert of interconnected neural systems that can adapt to changes in the availability of information and the processing abilities of the individual.
However, many questions remain about how various brain areas interact under different circumstances to facilitate speech perception and production.

We welcome contributions from a wide range of research on speech perception and/or production from different sensory modalities including:
(1) Novel experimental findings using brain imaging and/or electrophysiology
(2) Behavioral research with healthy and clinical populations
(3) Theories and models
(4) Reviews and opinions
