Reduced speech activity and hypokinetic phonation in communicating hydrocephalus following subarachnoid hemorrhage.

The case of a patient whose speech activity was impaired by communicating hydrocephalus following subarachnoid hemorrhage and improved after a ventriculoatrial shunt, is reported. A phonetic description and evaluation of the patient's voice is given, with the conclusion that there is a relationship between the reduction of speech activity and the hypokinetic quality of phonation.
