Abstract
Acoustic and perceptual correlates of Russian syllable-final plain and palatalized coronal stops were investigated. The acoustic analysis based on the data from six talkers showed that the stops were consistently released both word-finally and before stops. Both consonants in final position were strongly affricated and aspirated. The VC transitions to palatalized stops extended for more than half of the vowel, substantially affecting its quality. The perception experiment (12 listeners) determined that both bursts and transitions were perceptually relevant to the identification of the two phonemes. The contrast in final and preconsonantal environments differed in the relative importance of these cues: VC transition was more important for the plain-palatalized distinction in final position, while burst was a major cue to the contrast in preconsonantal position. The findings suggest that the presence of the plain-palatalized phonemic contrast in perceptually less favorable syllable coda positions is compensated for by additional acoustic information that assists a listener in the recoverability of the contrast.

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.
