Idiosyncratic consonant clusters: a Farsi-speaking child with protracted phonological development
Bibliographic record
Abstract
This study presents a nonlinear phonological analysis of speech data from a Farsi-speaking child with protracted phonological development (aged 4;8) with very low accuracy on consonants. Results revealed some common phenomena (fricatives produced as stops; dorsals and non-anterior coronals produced as anterior coronals) and some uncommon phenomena (nasals produced as oral stops; voicing and devoicing of singleton obstruents in all word positions). These phenomena interacted in word-medial clusters to create an unusual sequence of two anterior-coronal or two bilabial stops, with C1 voiced and C2 voiceless, clusters which do not occur in the basic phonology of Farsi spoken by adults. We present a non-linear constraints-based analysis of the child's speech production and a plan for intervention targeting the child's special difficulties.

How this classification was reachedexpand
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.
