Morphological status and acoustic realization: Is there a difference between Bra[d] Pitt and a grille[d] cheese omelet, or between Kate Mo[s] and killer robot[s]?

Abstract

This paper investigates the acoustic realization of morphemic and non-morphemic S and D in English. Two corpus studies are reported that examine the effect of morphological structure on fricative center of gravity and on stop duration. Multiple linear regression is used to isolate these effects. The results demonstrate the importance of morphological structure in speech production
