An EPG study of allophonic variation in the gestural magnitude of English lingual consonants
Bibliographic record
Abstract
Previous work on English glides and liquids has shown that certain (consonant) gestures are most constricted in initial allophones, least constricted in final allophones, and constricted to an intermediate degree in ambisyllabic or resyllabified allophones. It is not known, however, whether this generalization applies to other consonants such as stops and fricatives. As the point-tracking and imaging techniques used in previous studies are not well suited for measuring these types of segments, the present paper will present the results of an EPG study testing the degree of tongue contact during lingual consonants in these three syllable positions. Results of a pilot study using two subjects and a reduced set of consonants were mixed, failing to replicate previous findings for some previously measured consonants (e.g., /n/), while supporting the predicted pattern for others not previously measured (e.g., /z/). Results will be presented for additional subjects using the full inventory of lingual consonants. [Work supported by NSERC.]

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
