Abstract
The role of cue reweighting in reshaping tone sandhi patterns has rarely been discussed. The prevailing view is that, in Shanghainese disyllabic prosodic words, F0 distinctions between lexical tones are neutralised in the second syllable, while voice onset time (VOT) and closure duration function as the primary cues maintaining the voicing/register contrast. However, this study argues that a cue reweighting process is currently reshaping Shanghainese sandhi patterns: F0 is beginning to replace VOT and closure duration as the primary cue for voicing/register contrast in the second syllable position. This gradual acquisition of primary cue status by F0 in sandhi tones closely resembles processes of tone split observed in initial positions in other languages.

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 it
