Abstract
Muysken (2019) has argued that the most convincing cases of contact-induced change in heritage languages involve the dominant language having two distinctions mapping on to one (2-to-1). Evidence of such a case from Toronto heritage Cantonese will be discussed. Toronto English (the dominant language) has an allophonic split in which the TRAP vowel is raised and fronted in pre-nasal contexts. This is argued to influence the development of a similar allophonic split, led by lower proficiency speakers, in which Cantonese /ɛ/ is fronted before nasal consonants. The lack of an /ɛ/ split in Hong Kong Cantonese provides further support for contact-induced change. Unlike cases of a 1-to-2 mapping leading to a loss of a distinction in the heritage language (which can be argued to be internally motivated), this contact-induced split leads to increased phonological complexity, which is inconsistent with a deficit view of heritage language speech production.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
