Disorders of speech and voice

The focus of this article has been on the disorders of the motor aspects of speech and voice production, as contrasted with the symbolic aspects of the communication process (language). Categories of motor speech problems include those in which the articulation of speech sounds is aberrant, phonatory problems related to laryngeal function, those resulting from craniofacial anomalies, and finally those characterized by disruption in the flow or fluency of speech. Guidelines for timing and type of referral have been suggested. In each case, early referral is urged so that diagnosis of the problem based upon complete assessment can serve to guide treatment planning. Parental reports and concerns about a child's speech development (as well as language, cognitive and auditory behavior) should be given credence and attended to rather than ignored or postponed. Speech disorders are often amenable to total resolution and almost always to a significant degree of improvement, especially if diagnosed and treated early.
