Abstract
In this study, we provide nasendoscopic observations illustrating phonetic contrasts in Arabic that require supraglottic laryngeal adjustments, and demonstrate how the laryngeal constrictor mechanism contributes to phonetic descriptions of phonation. Arabic has two pharyngeal consonants (voiceless and voiced). We show, among others, that these two consonants possess auditory features of whisperiness and creaky voice, respectively, and are always produced with supraglottic constriction similar but more marked than during whispery or creaky [i]. However, during modal [i], the epilaryngeal space is wide open. We outline a revised model of laryngeal constriction where 'voice' is controlled to a large degree by supraglottic as well as glottic mechanisms. Some hypotheses are also proposed concerning the possible muscular synergies that induce these supraglottic gestures.

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
