I've been undertaking fieldwork with English speakers from Dearborn to better understand the perception and production of sociophonetic features in the area. I'm using what I learn to plan a psycholinguistics experiment and program GANs to model language contact.
Prior to candidacy I undertook an acoustic analysis of Ojibwe and English vowels using a corpus of radio audio from Minnesota Native News broadcasts.
The goals were 1. to provide acoustic and sociophonetic description of Ojibwe as well as Minnesota English spoken by Ojibwe people, and 2. to examine contact effects when the two languages are spoken in contact.
I found that speakers maintain unique vowel distinctions in English and Ojibwe, even when they do not fit the typical profile of a 'fluent' or 'L1' speaker. Further research is needed to evaluate the effects of contact, both synchronically and diachronically.
