Abstract
Words distinguished by a fricative-affricate contrast (dish-ditch and lash-latch) were produced in sentence contexts by native English speakers at five successively increasing speaking rates, from their slowest natural rate to their fastest rate possible without misarticulation. Durations of stop closures and fricative noises in the affricate cases, or fricative noises alone in the fricative cases, were measured from oscillograms. Least mean-squares lines relating durations of these acoustic segments to sentence duration were fitted to these data. Slopes of these functions were generally smaller for stop closures than for fricative noises, indicating that stop closures are more stable in duration across speaking rate than are fricative noises. The results are related to recent perceptual studies of the fricative-affricate distinction [e.g., A. M. Liberman, B. H. Repp, T. Eccardt, and D. Pesetsky, J. Acoust. Soc. Am. 62, S78(A)(1977)].
