SPEECH MOTOR TIMING.

Timing is a fundamental aspect of speech motor control. In a recent, prominent view towards speech timing, temporal organization is seen as arising from the interactions of peripheral articulatory structures and is not considered to be subject to external neurocognitive control. Evidence and arguments countering the main study supporting this position are critically reviewed. New data is presented in favor of neurocognitive control (possibly via the cerebellum) over two specific types of speech timing, rhythm and interarticulatory coordination. It is shown how such a notion of external control can be integrated into a general multifactorial experimental approach towards timing. The multifactorial approach is further illustrated with respect to hypotheses arising from Lindblom's distinction of hyper- and hypospeech. [ABSTRACT FROM AUTHOR]
