This sociophonetic study examines affricate variation through a continuous lens using diachronic data from Caracas Spanish. We investigate the relationship between frication and occlusion period duration in affricate segments across two steps. First, we present a phonetic characterization of the dependent variable and its variants. Second, we examine the sociolinguistic profile of the variants in an oral corpus of Caracas Spanish. Correlation analyses between the frication period, occlusion period, and overall segment duration suggest that frication lengthening is most prominent, which may mean that affricate variation in Caracas is not necessarily a lenition process, but rather a lengthening one. Through a mixed-effects linear regression model, we determine that frication duration is significantly conditioned by social and linguistic factors in Caracas. Longer frication periods are predicted by following high vowels, corpus year, speaker sex, and in word-initial position. These results suggest that traditional affricate lenition may in some cases point to a process of lengthening and retiming that is both socially and linguistically stratified. This paper contributes to the field by providing an acoustic examination of variable affricate production as well as a diachronic sociolinguistic investigation of this phenomenon in the Spanish of Caracas, Venezuela.
