【 摘 要 】

The need to reduce the dimensionality of movement systems, and thereby to decrease cognitive load, has long been recognized as a central challenge for theories of motor control (Bernstein, 1967). A large body of work in neurophysiology, biomechanics, and computation has substantiated the view that control of body movements is distributed among a manageable number of degrees of freedom corresponding to neuromuscular modules (e.g., Bizzi et al., 1991), or proportionally fixed groupings of muscles (see e.g., Ting et al., 2012 for a recent review). Current work in computational neuroscience provides evidence that the nervous system uses such modules to achieve dimensionality reduction (e.g., Berger et al., 2013). It is our opinion that a fully realized modular approach to speech movement will have a profound impact on models of speech.
