Speech disorder: A disorder affecting the ability to produce normal speech. Speech disorders may affect articulation (phonetic or phonological disorders); fluency (stuttering or cluttering); and/or voice (tone, pitch, volume, or rate). Speech disorders may have their roots in oral-motor difficulties, although some involve language processing problems. Diagnosis is made through speech/language assessment that is performed by a licensed speech/language pathologist. Treatment is by speech therapy.
