Investigating the emphatic feature in Iraqi Arabic
Bibliographic record
Abstract
The secondary place of articulation for Arabic emphatic consonants varies across dialects. This study examines two speakers of Iraqi Arabic, using acoustic evidence, and one speaker of Iraqi Arabic, using direct visual articulatory (transnasal laryngoscopic) evidence, to investigate the phonetic nature of the secondary feature and the prosodic effect of an emphatic consonant over multisyllabic words. The acoustic and laryngoscopic evidence suggests that the articulation of emphatics in Iraqi Arabic involves a modification of the shape of the pharynx which could be called pharyngealisation, which differs, however, from the pharyngeal configuration for producing pharyngeal consonants. While laryngeal constriction, with tongue retraction and larynx raising, characterises pharyngeals, larynx height appears to be low in the secondary articulation accompanying emphatics, while the tongue dorsum appears to be raised, giving the pharynx a singularly contrasting, narrowed configuration to that found in pharyngeals. Furthermore, the effect of an emphatic spreads to all syllables, forwards or backwards, regardless of its position in the word, although the effect is modified or blocked in certain phonotactic conditions.

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.
