Abstract
In early stages of classroom language learning, many adult second language (L2) learners communicate primarily with one another, yet we know little about which speech stream characteristics learners tune into or the extent to which they understand this lingua franca communication. In the current study, 25 native English speakers learning German as a L2 with varying levels of German proficiency rated German speech produced by native speakers and fellow learners of German along three continua: accentedness, fluency, and comprehensibility. An examination of speech stream (i.e., phonological, fluency based, and lexical/grammatical) characteristics along with partial correlations indicates both that the raters distinguished among the three concepts but that they conflated the term fluency with proficiency. Self‐reported proficiency in German and linguistic training were the best predictors of the ratings assigned.

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
