Speech and language disorder with orofacial dyspraxia Developmental verbal dyspraxia ( DVD ), also known as childhood apraxia of speech ( CAS ) and developmental apraxia of speech ( DAS ), [ 1 ] is a condition in which an individual has problems saying sounds, syllables and words.
Although disorders such as expressive aphasia, conduction aphasia, and dysarthria involve similar symptoms as apraxia of speech, the disorders must be distinguished in order to correctly treat the patients. [citation needed] While AOS involves the motor planning or processing stage of speech, aphasic disorders can involve other language processes.

For example, an inability to lick one's lips, wink, or whistle when requested to do so.

Childhood apraxia of speech (CAS) is a neurological childhood speech sound disorder that involves impaired precision and consistency of movements required for speech production without any neuromuscular deficits (ASHA, 2007a, Definitions of CAS section, para. 1).
The DSM-5 and the ICD-10 are both used to make specific diagnostic decisions. Speech and language disorders commonly include communication issues, but also extend into various areas such as oral-motor function—sucking, swallowing, drinking, or eating. In some cases, a child's communication is delayed considerably behind his/her same-aged peers.
