Perceptually fluent and disfluent speech reflect a continuum of coordination and can be best understood in terms of similar motor control processes. Speech movements may be considered to result from the interaction of inputs to motoneuron pools which alter the tuning of sensory-motor pathways and triggering inputs to specific muscles and muscle groups. A disorder incoordination may occur when any of these inputs is aberrantly affected by psychological, psychosocial or physiological variables. Specific phenomena associated with stuttering--adaptation, masking, whispering and voicing deviations--are interpreted in terms of these neuromotor processes. Therapeutic considerations are discussed.
感知流畅和不流畅的言语反映了一系列的协调性，并且从类似的运动控制过程角度能得到最好的理解。言语运动可被认为是运动神经元池的输入相互作用的结果，这些输入改变感觉运动通路的调谐，并触发对特定肌肉和肌肉群的输入。当这些输入中的任何一个受到心理、社会心理或生理变量的异常影响时，可能会出现协调障碍。与口吃相关的特定现象——适应、掩蔽、低语和发声偏差——根据这些神经运动过程进行解释。文中还讨论了治疗方面的考虑因素。
