Evidence for the Role of Gestural Overlap in Consonant Place Assimilation

Larissa H. Chen

Yale University, USA

Two hypotheses were tested: 1) Increasing the overlap between a coronal and a following non-coronal can result in the coronal gesture being heard as reduced in magnitude. 2) This relation does not hold for a non-coronal followed by a coronal. Computational models were used to generate and "listen" to several tokens ofhe of the test sequences "bad ban" and "bab Dan," which varied in their combinations of reduction and overlap levels. The original generated articulatory configurations were compared to the recovered ones, and from this the relationship between overlap and reduction was examined, both as they were produced and as they were recovered Results support the hypotheses that overlap can sometimes masquerade as reduction, and that the effect is asymmetrical in a way that is consistent with a previously proposed hierarchy of constraints on place assimilation.
