Previous work on stop consonant weakening, or lenition, in Romance languages has been discussed in terms of driving factors behind language variation and change; however, most of these studies do not provide data on the acoustic variability of stop consonants or the effects of linguistic (e.g., point of articulation, prosodic position, lexical stress) or extralinguistic (e.g., age, gender, and dialect) factors. My research acoustically and sociolinguistically analyzes Spanish’s stop consonants /ptk/ and /bdɡ/ across multiple varieties, which generates a lenition continuum ranging from weak to strong as well as commentary on the current state of their variation across the Spanish-speaking world. The data set used for my dissertation, extracted from the Atlas interactivo de la entonación del español (Prieto & Roseano 2009-2013) corpus, comes from the following regions: Spain, the Canary Islands, Argentina, Chile, Mexico, the Caribbean and the Andes. Trends show that while /ptk/ and /bdɡ/ remain distinct categories within each variety studied, the degree of consonant occlusion varies greatly inter-dialectally. For example, Mexican Spanish /ptk/ and /bdɡ/ are produced with greater occlusion whereas the same segments in some Peninsular and Caribbean varieties are much more open, with /bdɡ/ often experiencing total deletion. The data also shows a slight overlap of the production of the most radical, less occluded /ptk/ in Caribbean Spanish with the most conservative production of /bdg/ in Mexican Spanish, yielding implications for future work on consonant perception. Concerning age and gender, younger speakers as well as male speakers tend to produce less occluded, more open stop consonants. Overall, this investigation fills existing research gaps by making suggestive points regarding diachronic language change evidenced by synchronic consonant variation, the variation across multiple Spanish varieties, sociolinguistic effects on weakening and the geographical spread of consonant lenition.
