Research has shown that speech segment perception is predominantly a function of the left hemisphere. The aim of this study is to determine if the visual field in which visual speech is presented affects the audiovisual percept. Results show increased audiovisual fusion in the right visual field and exclude that the difference was a result of facial asymmetry. Findings indicate more efficient early audiovisual processing in the right visual field, likely associated with early left hemisphere brain functions for speech segments.
