Abstract
This paper provides a detailed phonetic, synchronic description of the oral vowels of Upper Tanana, an Athabascan language spoken in eastern interior Alaska and the western Yukon Territory. Upper Tanana has, depending on the dialect, six or seven oral monophthongs that can be modified for (low) tone, nasalization, and length. Previous accounts are auditory. They disagree regarding the articulation of two of the vowels (which we represent as /ɘ/ and /ʌ/), and raise the question of whether ‘length’ indicates a quantity or a quality distinction. In contrast to earlier accounts, we provide acoustic measurements of F1, F2, and the duration of the vowels of two Alaskan dialects of Upper Tanana: Northway and Tetlin. We find that the phonetic realization of one of the vowels is quite different from the earlier auditory descriptions. For the other vowels and for the quantity distinction, our findings support earlier descriptions while supplying new details. Several co-articulation effects, previously undescribed, are also identified.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
