Phonological acquisition of European Portuguese oral vowels: A forced-choice identification study with Hungarian native speakers
Bibliographic record
Abstract
Auditory perceptual experiments with Portuguese L2 are scarce, especially within the scope of the European variety (EP). In this study, we aim at observing the assimilation of the EP vowels [ɐ] and [ɨ] by Hungarian native speakers, and their perceptual learning after some contact with Portuguese. A multiple forced-choice identification experiment was run with two groups of Hungarian speakers – a group with and a group without previous contact with EP. The results show that the categorization fell into the closest phonetic categories of the L1. The results also indicate a learning effect for [ɨ], with a recategorization path from [y] to [ø]. As for [ɐ], no major differences were observed between groups. This result is consistent with difficulties observed in the classroom environment, where [ɐ] is particularly challenging to Hungarian learners.

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.
