This study investigates the acoustic property of aspiration realized in English voiceless stops of /Cr/ and /sCr/ clusters. VOT is measured from stops in these clusters produced by two groups; one from native speakers of English and the otherfrom Korean native speakers. Aspiration of stops in different types of clusters is compared to various phonological factorssuch as location of stress, syllable type, and position in word. Pursuing the idea that phonetic realization is correlated withphonological representation, attempts are made to account for the gradient nature of aspiration of stops on the basis ofsyllable structure at the phonetic level, which may vary in the wake of resyllabification. Voiceless stops in /Cr/ and /sCr/clusters are further compared to results obtained in the previous study on /sC/ cluster. Variations in aspiration are alsocharacterized in terms of segmental precedence relation of stops in the clusters, namely, post-[s], pre-[r], or both.
