Neurolinguistics and Research in Speech Production
"The nature of neurolinguistic programmes has attracted a great deal of research in recent years, especially in relation to speech production. It is evident, for example, that the brain does not issue motor commands one segment at a time. . . . When we consider the whole range of factors that affect the timing of speech events (such as breathing rate, the movement and coordination of the articulators, the onset of vocal-fold vibration, the location of stress, and the placement and duration of pauses), it is evident that a highly sophisticated control system must be employed, otherwise speech would degenerate into an erratic, disorganized set of noises. It is now recognized that many areas of the brain are involved: in particular, the cerebellum and thalamus are known to assist the cortex in exercising this control. But it is not yet possible to construct a detailed model of neurolinguistic operation that takes all speech-production variables into account."
