This paper examines factors affecting vowel reduction that occurs in the environment of stress clash. Previous studies have indicated that vowel reduction motivated by stress clash is influenced by frequency, and is affected in general by the structure of the syllable in which it occurs, by the nature of that syllable's coda consonant, and by the structure of the preceding syllable. Based on 348 morphologically complex words whose derivation from their base words takes place in the environment of stress clash, this paper presents statistical analyses to determine whether these factors indeed have any effect on the occurrence of vowel reduction in the stress clash environment. Multiple regression analyses reveal that the influence of the following factors are statistically significant: (i) derivative and relative frequencies; (ii) presence/absence of a coda consonant; (iii) place/manner of articulation of the coda consonant; and (iv) prominence and structure of the preceding syllable. Statistical results further indicate that open syllable, higher derivative frequency, and coronal coda are the three most influential variables contributing to vowel reduction in the environment of stress clash.
