The Effects of Post-Velar Consonants on Vowels in Nuu-chah-nulth: Auditory, Acoustic, and Articulatory Evidence
Bibliographic record
Abstract
Abstract Previous phonetic documentation of Nuu-chah-nulth consonant-vowel interactions has either solely relied on transcriptions or has been incomplete in some other respect. Using auditory, acoustic, and articulatory evidence, this article documents the effects of all post-velar consonants on all vowels. Results show that /i/ and /i:/ almost always have a schwa offglide before the uvular and pharyngeal stops, but not always before the fricatives. When these vowels follow uvulars and pharyngeals (with the exception of the labialized uvular), they are usually lowered and do not have a schwa offglide. Ultrasound data confirm that the tongue root is active in articulating uvular and pharyngeal consonants and that the schwa off-glide occurs because the tongue is moving through a schwa-like configuration on its way from the high front vowel to the retracted consonant. The vowels /u/ and /u:/ are lowered and/or diphthongized following (but not preceding) pharyngeals, and they are unaffected by uvulars.

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.
