Clausal Intonation After Unilateral Brain Damage

Abstract

Thirteen right-handed adult speakers, including five patients with unilateral left-hemisphere damage, four patients with unilateral right-hemisphere damage, and four patients with non-neurological damage, read aloud sentences designed to test influences of clause and utterance length on two acoustical measures of intonation, fundamental voice frequency ( Fo) and timing. Patients with unilateral damage to the left-hemisphere exhibited more abnormality in Fo and speech timing than did patients with right-hemisphere damage.
