This study investigates imitation of English /s/ to determine whether speakers converge toward normalized or raw acoustic targets. Participants exposed to increased spectral mean (SM) raised SM, converging toward both the raw acoustics of the model talker (who had high baseline SM) and the pattern of increased SM. However, after exposure to decreased SM, direction of shift depended on participant baseline.

Individual talkers vary in their relative use of different cues to signal phonological contrast. Previous work provides limited and conflicting data on whether such variation is modulated by cue trading or individual differences in speech style. This paper examines differential cue weighting patterns in Mandarin sibilants as a test case for these hypotheses.

This paper reconsiders a classic claim about phonetic variability-that speech sounds in larger phonemic inventories should exhibit less within-category variability in production. Although this hypothesis is intuitive, existing literature provides limited unqualified support for the claim, further complicated by the fact that null results (like those failing to find a difference in variability between languages) often go unpublished. Even so, existing work suggests that factors contributing to extent of variability are multifaceted.

Dispersion Theory [DT; Liljencrants and Lindblom (1972). Language 12(1), 839-862] claims that acoustically dispersed vowel inventories should be typologically common. Dispersion is often quantified using triangle area between three mean vowel formant points.
