The authors assessed tardive dyskinesia and the structure and physiolo gy of speech apparatus, phonation, and articulation speech abnormaliti es in 27 chronically ill male psychiatric patients. Tardive dyskinesia was associated with impairment in phonation, intelligibility, and rat e of speech production. Patients with and without tardive dyskinesia h ad similar rates of structural and physiological abnormalities of spee ch apparatus. The authors conclude that tardive dyskinesia is associat ed with substantial impairment in speech.
