This studyinvestigates how the duration of consonants is modulated in relation tonon-adjacent consonants. Oh et al. (2020) provide evidence that non-adjacentlong stops (e.g., aspirated) influence each other. They attribute this modificationto the inclination to maintain a regular vowel-to-vowel (V-to-V) interval. Theirclaim is based on the data where a vowel intervenes between long stops. Underthe interval account, it would be expected that such duration modulation of longstops will also occur when a vowel and a consonant intervene between longstops. To test the validity of the interval analysis, a production experiment wasconducted with 16 Korean speakers producing words with oral stops and /n/ forC1 and C2 in both C1aC2a and C1anC2a sequences. The results indicate theshortening effect of long consonants is nullified by an intervening nasal coda,and the nasal stop is unaffected by non-adjacent consonants, unlike oral stops. This effect is attentive to phonological features rather than phonetic duration. Additionally, it is bidirectional, with the regressive effect being more prominent. These findings lead us to the conclusion that, during articulation processing,speakers anticipate the next consonant, focusing on its phonological featuresand they adjust consonant duration as nec...
