The Role of Perception in the Typology of Geminate Consonants: Effects of Manner of Articulation, Segmental Environment, Position, and Stress.

The present study seeks to answer the question of whether consonant duration is perceived differently across consonants of different manners of articulation and in different contextual environments and whether such differences may be related to the typology of geminates. The results of the cross-linguistic identification experiment suggest higher perceptual acuity in labeling short and long consonants in sonorants than in obstruents. Duration categories were also more consistently and clearly labeled in the intervocalic than in the preconsonantal environment, in the word-initial than in the word-final position, and after stressed vowels than between unstressed vowels. These perceptual asymmetries are in line with some typological tendencies, such as the cross-linguistic preference for intervocalic and post-stress geminates, but contradict other proposed cross-linguistic patterns, such as the preference for obstruent geminates and the abundance of word-final geminates.
