phonologic disorder
developmental phonological disorder
Any of a group of speech disorders which affect children’s ability to develop easily understood speech by age 4. Developmental phonological disorders are characterised by difficulty in learning and organising sounds needed for clear speech, reading and spelling. They are often familial, and may occur with other communication disorders—e.g., stuttering, specific language impairment, or developmental speech apraxia.Segen's Medical Dictionary. © 2012 Farlex, Inc.
