In Ecuador there exists a dynamic language contact continuum between Urban Spanish and Rural Quichua. This study explores the effects of competing phonologies with an analysis of voice onset time (VOT) production in and across three varieties of Ecuadorian highland Spanish, Quichua, and Media Lengua. Media Lengua is a mixed language that contains Quichua systemic elements and a lexicon of Spanish origin. Because of this lexical-grammatical split, Media Lengua is considered the most central point along the language continuum. Native Quichua phonology has a single series of voiceless stops (/p/, /t/, and /k/), while Spanish shows a clear voicing contrast between stops in the same series. This study makes use of nearly 8,000 measurements from 69 participants to (i) document VOT production in the aforementioned language varieties and (ii) analyse the effects of borrowings on VOT. Results based on mixed effects models and multidimensional scaling suggest that the voicing contrast has entered both Media Lengua and Quichua through Spanish lexical borrowings. However, the VOT values of voiced stops in Media Lengua align with those of Rural and L2 Spanish while Quichua shows significantly longer prevoicing values, suggesting some degree of overshoot.
