Abstract

fetched live from OpenAlex

A study was conducted to investigate whether second language (L2) learners had the ability to produce English vowels when they were presented in more familiar words and when learners had access to orthographic representations of those words. A number of Standard Mandarin-speaking and Slavic students participated in the study. All these students had enrolled in intensive ESL classes for an average of 5.2 months and were assessed as beginners by the Canadian Language Benchmarks. Stimuli for the investigations comprised of a list of 30 English progressive verbs containing 10 target Canadian English vowels. Words were also selected to include a range of onsets so as to solve any potential contextual biases in performance. The resulting word list was randomized and a male speaker of Canadian English was recorded producing each word with a five second pause inserted between items.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
