The phonetic realization of intonational targets in the f0 contour is not always straightforwardly predicted by their affiliations in the segmental string, and the phrase tones of American English are a type of target for which several hypotheses about the domain of realization have been advanced. By varying the metrical structure of target words at the end of a phrase produced with the H* L- H% ‘surprised dismay’ contour, we determined that a) the right edge of the L, signaled by the beginning of the rise for the H%, occurs close to the right edge of the phrase, b) the left edge of the L-, signaled by the end of the fall from the H*, stretches leftward to seek a prominent syllable, and c) there is significant variation in the resolution of the various factors that influence these two inflection point locations.
