The perceptual foundations of phonological development
Bibliographic record
Abstract
Abstract Phonological development involves learning the organisation of the individual sound units, the syllable structure, the rhythm, and the phonotactics of the native language, and utilising these in both productive and receptive language. The initial work in phonological development focused exclusively on production, with detailed description of the onset of babbling and first words. This article examines how infant speech perception provides a foundation for acquiring the phonological system, and how production data and perception studies together can provide a more complete picture of the course of phonological development. The discussion begins with a review of key empirical findings that show how speech perception provides the foundation for phonological development. It then looks at language-general speech perception capabilities as evident in infants from birth through the first few months of life. The discussion also considers the ways in which the ambient language modifies infant speech perception; phonological and phonetic factors in word segmentation and word form recognition; the role of phonology in early lexical comprehension; and theories and models of phonological development.

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.
