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 speed).
Most speech disorders have their roots in oral-motor differences, although some involve language processing problems.
Diagnosis is by testing by a speech pathologist.
Treatment is by speech therapy.
