Brief Summary

Understanding speech is one of the most important functions of the human brain. We use information from both the auditory modality (the voice the of person we are talking to) and the visual modality (the facial movements of the person we are talking to) to understand speech. We will use intracranial encephalography to study the organization and operation of the brain during audiovisual speech perception.
