The duration of phonetic components in a syllable is known to be affected by the syllable's relative prominence, along with the number and articulatory nature of phonological segments in a word. This study addresses the durational effect of these factors on successive segments in Swedish consonant clusters. Ten native Swedish speakers were recorded producing monosyllabic and disyllabic target words which were either focused or not focused in a carrier phrase. Each word contained an /s/+stop cluster or stop+/s/ cluster in which the stop was /p,t/ or /k/. The durations of the /s/ frication and stop closure were measured. Results indicate that focus consistently increases the duration of a cluster and its constituents. In addition, little difference in closure duration was observed among /p,t,k/. Within disyllabic words, the cluster's first segment, whether a stop or an /s/, was systematically longer than the second segment in both nonfocal and focal conditions. The reverse tendency was found for monosyllabic words; the cluster's second segment was generally longer than the first segment in the focal condition, and no difference due to position in the cluster was observed for the nonfocal condition. These results are discussed in terms of the relative timing of successive consonants within clusters.
