Key findings
A neural-network model whose components correspond to premotor, motor, auditory, somatosensory cortex, and cerebellum reproduces lip- and jaw-perturbation compensation during speech, and anatomically grounded simulations of fMRI experiments match observed activations for simple syllable production.
Abstract
Source: pubmed
This paper describes a neural model of speech acquisition and production that accounts for a wide range of acoustic, kinematic, and neuroimaging data concerning the control of speech movements. The model is a neural network whose components correspond to regions of the cerebral cortex and cerebellum, including premotor, motor, auditory, and somatosensory cortical areas. Computer simulations of the model verify its ability to account for compensation to lip and jaw perturbations during speech. Specific anatomical locations of the model's components are estimated, and these estimates are used to simulate fMRI experiments of simple syllable production.
