These exclamatory plateaus can be accounted for by positing two H edge tones, with no utterance-final boundary tone.
This type of contour can be explained with three edge tones: a L at the beginning, a H on the second or third syllable and a H at the end.

Intonationally speaking, then, wh questions and yes-or-no questions with interrogative words differ from simple questions in having only one high initial target (H) representing a H edge tone, and a H utterance-final boundary tone (H%).
Notice that the H tone triggering this peak is the only one in the Wolof system that is not a phrasal edge tone or an utterance boundary tone.
