Clausal Intonation After Unilateral Brain Damage

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 (F o) and timing. Patients with unilateral damage to the left-hemisphere exhibited more abnormality in F o and speech timing than did patients with right-hemisphere damage.
