Neurolinguistic Aspects of Speech Production
Overt speech is the consequence of a series of interrelated events. First there must be an intention to speak and some knowledge of the type of speech act which appropriately fits the occasion. Is the utterance for example, to be declarative, questioning or requesting? In what style must the listener be addressed? Intimate conversational or public oratorial? So that the meaning of the message may be conveyed a linguistic programme must be assembled in which lexical items are arranged in semantic and syntactic units acceptable to the particular linguistic environment. These units are in turn the outcome of patterned phonological sequences. Abstract levels of planning must then be translated into neuromuscular commands to enable the vocal tract musculature to achieve the correct configuration for the production of a sequence of sounds recognizable to the listener. Not only the listener, but also the Speaker perceives the utterance through the medium of multi-sensory feedback circuits.
