It is also worth noting that in those cases, simultaneous peak and valley resets are found. It appears from these results that the frequency of occurrence of resets can be related to the degree of syntactic cohesion. An examination of the shape of the F0 contour shows that an F0 peak is consistently present in the syllable preceding the boundary when a pause is not produced. The presence of this peak could be also explained as a function of the lexical accent. Nevertheless, the presence of a peak simultaneously to the stressed syllable preceding the boundary suggest that NP-VP boundaries may, at least in some cases, inhibit peak displacement, so that F0 peaks could mark the boundary.
Resets also tend to appear at syntactic boundaries.
It is worth noting that they seem to be related to the occurrence of a pause in the case of NP-VP boundaries. The discrimination of the type of syntactic boundary by means of prosodic cues has also been studied. It seems clear that vowel duration does not distinguish between the types of syntactic boundaries observed. The F0 shape at boundaries without pause does not seem to contribute either to this differentiation. Resets could be then related to major boundaries.
