Acoustic Variability of /ptk/ and /bdɡ/ in Spanish: A Pilot Study

Abstract

Propelled by existing research on stop consonant variability in Spanish, this pilot study provides a preliminary acoustic analysis of stop consonant lenition exhibited by speakers of six different varieties of Spanish in Latin America and Spain to explore the gradient acoustic variability in the production of /ptk/ and /bdɡ/ among speakers of different Spanish varieties. Using the acoustic correlate of relative intensity, this analysis considers the effect of various linguistic factors (phoneme, lexical stress, point of articulation, sonority) as well as the extralinguistic factor of Spanish variety on the production of stop consonants in initial, intervocalic position. Results display a higher degree of weakening among speakers of Peninsular and Insular varieties of Spanish compared with those of Latin-American varieties such as Colombian, Mexican, and Peruvian. These exploratory data support the gradient nature of consonant lenition and provide a baseline for future research on stop consonant variability across the Spanish-speaking world.
