Neural speech is a research field dedicated to understanding the neural substrates and mechanisms underlying human spoken communication. It investigates the brain processes involved in speech production, perception, and processing, utilizing neuroscientific methods such as neuroimaging, electrophysiology, and computational modeling to map neural activity to linguistic and acoustic features. The significance of this field lies in advancing fundamental knowledge of brain function related to language and enabling the development of neuroprosthetic technologies for restoring speech in individuals with communication impairments.
