This paper reports results of an acoustic study of stress in the Turkish dialect of the Northwest Caucasian language, Kabardian. Stressed syllables were found to have consistently higher fundamental frequency and characteristically greater duration and intensity than unstressed syllables. No evidence was found for secondary stresses. Schwa and, to a lesser extent, /ɐ/ were shown to undergo slight raising as their duration in unstressed syllables decreased. This gradient raising is likely due to coarticulatory overlap with adjacent consonants rather than a categorical shift in vowel quality. Considerations of articulatory effort rather than perceptual dispersion predict both the categorical alternation between stressed /aː/ and unstressed /ɐ/ in Kabardian and the non-categorical raising of schwa and /ɐ/ in unstressed syllables.
