Acoustic prominence production in Parkinson's disease when there is a shared communicative goal
Bibliographic record
Abstract
This study quantified the acoustic characteristics of prominence in people with Parkinson's disease (PD) when engaging in a communicatively driven task in which they read aloud instructions to a partner. Twelve people with PD and 14 controls read aloud instructions to a researcher in a simple communicative barrier game. Stimuli were designed to manipulate prominence on a target word that contrasted with a minimal pair that differed in the onset consonant. Outcomes included acoustic measures of prominence as a function of group and prominence condition. Overall, people with PD manipulated prominent words in similar ways to controls with respect to speech intensity and duration. An attenuated use of f0 was found in the PD group to differentiate prominent and non-prominent words. Group differences, but not differences in prominence marking, were found for vowel formants. Results indicate that, overall, prominence marking is relatively preserved in people with PD in communicative settings, though how prominence is conveyed varies to some degree compared to neurologically healthy talkers.

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.
