Abstract
This paper reports the results of an experimental phonetic study examining pitch peak alignment in production and perception of three-syllable one-word sentences with phonetic rising-falling pitch movement by speakers of Russian. The first part of the study (Experiment 1) utilizes 22 one-word three-syllable utterances read by five female speakers of Russian as a declarative, an exclamation, and an interrogative. Significant differences in the alignment of pitch peak across declaratives and exclamations on the one hand and interrogatives on the other hand are observed. The second experiment tests whether these pitch peak alignment differences are employed in speech perception. Experiment 2 is performed with a series of resynthesized three-syllable stimuli which differ by 14 locations of the pitch peak, two segmental bases used for resynthesis (declarative and interrogative) and two heights of the pitch peak (270 and 320Hz). The results of the experiment demonstrate that a shift in pitch peak alignment strongly affects listeners' perception of sentence type. The effects of pitch height and segmental base are also significant. Implications for Russian intonation system are discussed.

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
