The term "verbal dyspraxia" is used by some scientists and clinicians to describe the inability to produce the sequential, rapid, and precise movements required for speech. Nothing is wrong with the child's vocal apparatus, but the child's brain cannot give correct instructions for the motor movements involved in speech. This disorder is characterized by many sound omissions. Some verbally dyspraxic children, for instance, speak only in vowels, making their speech nearly unintelligible. One little boy trying to say "My name is Billy" can only manage "eye a eh ee-ee." These children also have very slow, halting speech with many false starts before the right sounds are produced. Their speech errors may be similar to those children with phonological impairment.
