These two examples are two calling contours: the first is neutral and the second one is interrogative.
In both examples the contour is nearly the same: the first stressed syllable bears a low pitch accent, the nuclear pitch accent is rising, and the rise continues into the postaccented syllable.
These two sentences differ in the height of the peak at the end of the postaccented syllable: it is much higher in an interrogative contour (HH%) than in a neutral calling contour (H%). |
