Abstract
Abstract This article examines differential substitution of the L2 English voiceless interdental fricative, [θ]. The L1s investigated in this study—European French, Québec French, and Japanese—have been reported to substitute [s], [t], and [s] respectively in production. Two main hypotheses are explored: 1) Transfer is perceptually based; 2) Substitution involves an assessment of non-contrastive in addition to contrastive features. Results of an AXB task show that advanced learners are unable to perceive certain non-contrastive distinctions; however, unlike Japanese listeners, French listeners do perceive Strident and Mellow, features which are non-contrastive in their L1. Results indicate a clear perceptual basis for the Japanese substitute. The difference between Québec and European French is less clear; however, there is a trend which suggests a perceptual basis for the European French substitute. Another finding is that confusion of [f] and [θ] is greater for French than it is for Japanese listeners. It is proposed that the composition of the L1 phonetic inventory influences which features listeners attend to during perception.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
