    Voice Onset Time in a language without voicing contrast: an acoustic analysis of Blackfoot oral stops
    (Cambridge University Press, 2024) Genee, Inge; Li, Fangfang
    This paper presents an acoustic analysis of Voice Onset Time (VOT) in oral stop consonants in Blackfoot, an Algonquian language without contrastive voicing. We focus on VOT as one of the key temporal acoustic correlates of voicing and investigate VOT variation in relation to (i) place of articulation (labial vs. alveolar vs. velar); (ii) length (long vs. short), quality (/a/ vs. /o/), and accent pattern (accented vs. unaccented) of the following vowel; (iii) word position (initial vs. medial); (iv) gender; and (v) age. We analyzed 2096 stop consonant tokens produced by 13 participants, who completed two different tasks: an English-to-Blackfoot translation task and a picture naming task. The key findings are as follows: (i) Blackfoot stop consonants fall into the short-lag range that overlaps with the English voiced category, with mean VOT values ranging from 11.6–32.7 ms; (ii) VOT values become progressively longer as the place of articulation moves to more posterior positions; (iii) VOT values are longer before high vowels than before low vowels; (iv) VOT values are longer before long vowels than before short vowels; (v) no statistically significant effect was found for the linguistic factors word position and accent pattern; (vi) no statistically significant effect was found for the socio-indexical factors age and gender; and (vii) no statistically significant effect was found for the experimental factor task type. The implications of our findings for the Blackfoot writing system and ongoing work on language documentation and revitalization are briefly discussed.
