Gender and lesion characteristics modulate the sibilant acoustics in continuous speech after tongue cancer surgery
Bibliographic record
Abstract
Oral and oropharyngeal cancer and its treatment can have a devastating impact on speech. The acoustics of 4385 productions of /s/ from 89 patients (66M,23F) mean age 58.67 (range 22–82 years) were analyzed before and after (1, 6, and 12 months) glossectomy surgery. Center of gravity of the fricative power spectrum (COG) was analyzed with a linear mixed effects model with assessment time, age, gender, and amounts of resections (%) within oral and pharyngeal structures as fixed effects and random intercepts for speaker and phonetic context. Before surgery, greater tumor invasion into the floor of the mouth, male sex, and older age lowered the COG. After surgery, COG was reduced (1 month: 1900 Hz; 6 months: 1520 Hz; 1 year: 1080 Hz) and dropped more for women than men. Lesion site impacts COG: the greater the tumour invasion in the tongue, the more the 1-month COG was lowered compared to the rest of the model pointing to a transient aggravating effect. The results suggest partial recovery of speech function at 1 year. The recovery is gendered with women remaining further away from the pre-treatment values after surgery. Future analysis will consider the effects of chemo-therapy and radiation. [Work supported by the Alberta Cancer Foundation, Grant RES0061908.]

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
