“…Subjects were asked to listen to the hoarse and normal lecture voice samples and check each adjective which matched the feelings which arose when they listened.

The preferred lecture voice was characterized to be bright, confident, clean and pleasant, delightful, enthusiastic, soft and kind, intelligible, dynamic in tone levels, loud and appropriate speed.…”
