Abstract

fetched live from OpenAlex

It is well known that whispered speech is able to convey information that is normally associated with pitch. For example, it is possible to whisper the question ‘‘You are going today?’’ without any syntactic information to distinguish this sentence from a simple declarative. It has been shown that pitch change in whispered speech is correlated with the simultaneous raising or lowering of several formants [e.g., Kallail and Emanuel, J. Speech Hear. Res. 27, 245–251 (1984)]. Data will be presented from 81 native speakers of English from the Halifax region of Nova Scotia (35 men and 46 women) who were asked to phonate and whisper the vowels /i,I,e,ε,æ,≳,o,U,u,■,■,■I,aU,aI/ at three different pitches across a range of roughly a musical 5th. Formant frequency variability is much greater for whispered vowels with different intended pitches resulting in much greater between-category overlap. Listeners’ categorizations of these stimuli will be reported as well as results from a discriminant analysis based on either static or dynamic spectral information. [Work supported by SSHRC.]

Not 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.
