Abstract

fetched live from OpenAlex

Much pronunciation research critically relies upon listeners’ judgments of speech samples, but researchers have rarely examined the impact of methodological choices. In the current study, 30 German native listeners and 42 German L2 learners (L1 English) rated speech samples produced by English-German L2 learners along three continua: accentedness, fluency, and comprehensibility. The goal was to determine whether rating condition, that is, (a) whether each speech sample is rated along all three continua after it is heard once or (b) whether all speech samples are rated along one continuum before being rated along the next continuum, and continuum order (e.g., whether participants rate speech samples for accentedness before comprehensibility or fluency) have an effect on listeners’ ratings. Results indicate no significant overall effects of rating condition or continuum order, but there is evidence of rating condition effects by listener group. The results have implications for laboratory and classroom assessments of L2 speech.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
