Anticipatory lip gestures: A validation of the Movement Expansion Model in congenitally blind speakers
Bibliographic record
Abstract
In this paper, anticipatory co-articulation of the lip protrusion and constriction gestures is investigated in speakers with visual deprivation. Audio-visual recordings of 11 congenitally blind French speakers producing [V-roundC-roundV+round] sequences were measured with a lip shape tracking system. Lip protrusion and constriction values and their relative timings were analyzed. Results show that despite the reduced magnitude of lip protrusion and constriction area in blind speakers, the timing of the anticipatory gestures can be appropriately modeled by the Movement Expansion Model [from Abry and Lallouache (1995a). Bul. de la Comm. Parlée 3, 85-99; (1995b). Proceedings of ICPHS, pp. 152-155; Noiray et al. (2011). J. Acoust. Soc. Am. 129, 340-349], which predicts lawful anticipatory behavior expanding linearly as the intervocalic consonant interval increases.

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.
