LANGUAGE-SPECIFIC PHONETIC PRODUCTION PATTERNS IN THE FIRST YEAR OF LIFE
Bibliographic record
Abstract
The production of sounds by infants from 1 to 12 months is evaluated according to place of articulation to verify the hypothesis that infants' production becomes language-specific towards the end of the first year. This study is based on an analysis of 4,499 sounds produced by 19 infants raised in one of 3 linguistic contexts: Canadian English, Moroccan Arabic, and Bai. Our results reveal that towards the end of the first year (10-12 months), infants show a preference for producing sounds at places of articulation that reflect their linguistic background, a finding that parallels results obtained in perceptual studies. Contrary to our expectations, however, the infants ' production at the end of the first year, albeit language-specific, does not directly correspond to the adult model. In the case of Bai infants, in particular, it was found that these infants use laryngeal constriction at a segmental level, while this phonetic feature is not employed in the adult model at a segmental level but at a syllable/word level for tone register contrasts.

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.
