There are three significant features that differentiate DVD/CAS from other childhood speech sound disorders. These features are: * "Inconsistent errors on consonants and vowels in repeated productions of syllables and words * Lengthened coarticulatory transitions between sounds and syllables * Inappropriate prosody, especially in the realization of lexical or phrasal stress" Even though DVD/CAS is a<unk>  disorder, it will not simply disappear when children grow older. Children with this disorder do not follow typical patterns of language acquisition and will need treatment in order to make progress.
