TL;DR: The neurologist will find the chapters on principles of neurologic function and hierarchy of motor organization rather basic and many speech pathologists may find the section on motor speech examination somewhat devoid of detail.
Abstract: The authors have limited consideration of motor speech disorders to dysarthrias of neurogenic nature. Aphasias (defined by the authors as problems of processing and symbolic formulation of the language code) are excluded. So are the deviant patterns of speech, such as developmental disorders of articulation and those disorders arising from structural impairments, such as cleft palate. A short but useful review of the basic motor process of speech production and its evaluation by clinical and other techniques is included. A more detailed description of relatively unfamiliar methods, such as palatography and videofluoroscopy would have been desirable. The neurologist will find the chapters on principles of neurologic function and hierarchy of motor organization rather basic. Other specialists may find these useful. On the other hand, many speech pathologists may find the section on motor speech examination somewhat devoid of detail. A disproportionately large space is allotted to the examination of the

TL;DR: Results suggest that temporal ratios between oral and laryngeal gestures tend to remain constant across changes in stress and speaking rate, consistent with those obtained for other aspects of speech motor control as well as for other types of human motor behavior, suggesting common modes of control.
TL;DR: The instrumental techniques of electropalatography and pneumotachography are used to examine details of tongue-palate contacts and VOT characteristics of three adult male subjects: two described as dysarthric and one as dyspraxic, and the results are compared with data from four normal speakers.
Abstract: The instrumental techniques of electropalatography and pneumotachography are used to examine details of tongue-palate contacts and VOT characteristics of three adult male subjects: two described as dysarthric and one as dyspraxic. A comparison is made between the subjects, and the results are compared with data from four normal speakers. The information is considered with reference to the neurological bases of these disorders of speech, and the advantages of an instrumental investigation over traditional auditory based assessments are exemplified. Some implications for therapy are also considered.
TL;DR: The present situation in Japan regarding development and application of the electro-palatography is reviewed and data on lingual articulation with respect to personal differences and child characteristics are reported.
