The relative duration of consonants and vowels of a syllable can be affected by factors such as focal stress, postvocalic voicing, and distinctive vowel length. Previous research has shown that focal stress generally affects both vowel and consonant durations within a syllable, whereas for both postvocalic voicing and distinctive vowel length, vowel and postvocalic consonant durations are inversely related. In fluent speech, the timing within a syllable will simultaneously reflect the influence of focal stress, postvocalic voicing and distinctive vowel length. The goal of the present study is to examine the combined effects of focal stress, postvocalic voicing and distinctive vowel length on vowel duration and neighboring consonants, and to characterize the concurrent effect of these factors on syllable- and rhyme-internal timing. Based on measurements within Norwegian C1VC2S, results indicate that (1) vowel duration is affected by the three factors investigated, (2) focal stress affects both vowel and consonant durations, and (3) closure duration of C2 is inversely related to the effects of postvocalic voicing and distinctive vowel length on vowel duration. These findings are discussed in terms of syllable- and rhyme-internal timing.
