Abstract

Objectives/Hypothesis: Distinguishing muscle tension dysphonia (MTD) from adductor spasmodic dysphonia (ADSD) can be difficult. Unlike MTD, ADSD is described as “task‐dependent,” implying that dysphonia severity varies depending upon the demands of the vocal task, with connected speech thought to be more symptomatic than sustained vowels. This study used an acoustic index of dysphonia severity (i.e., the Cepstral Spectral Index of Dysphonia [CSID]) to: 1) assess the value of “task dependency” to distinguish ADSD from MTD, and to 2) examine associations between the CSID and listener ratings. Study Design: Case‐Control Study. Methods: CSID estimates of dysphonia severity for connected speech and sustained vowels of patients with ADSD (n = 36) and MTD (n = 45) were compared. The diagnostic precision of task dependency (as evidenced by differences in CSID‐estimated dysphonia severity between connected speech and sustained vowels) was examined. Results: In ADSD, CSID‐estimated severity for connected speech (M = 39. 2, SD = 22.0) was significantly worse than for sustained vowels (M = 29.3, SD = 21.9), [P = .020]. Whereas in MTD, no significant difference in CSID‐estimated severity was observed between connected speech (M = 55.1, SD = 23.8) and sustained vowels (M = 50.0, SD = 27.4), [P = .177]. CSID evidence of task dependency correctly identified 66.7% of ADSD cases (sensitivity) and 64.4% of MTD cases (specificity). CSID and listener ratings were significantly correlated. Conclusion: Task dependency in ADSD, as revealed by differences in acoustically‐derived estimates of dysphonia severity between connected speech and sustained vowel production, is a potentially valuable diagnostic marker.

  • Auditory-only discrimination between SD and MTD is notoriously unreliable, contributing to widespread misdiagnosis.

    “auditory-only discrimination between SD and MTD is notoriously unreliable, contributing to widespread misdiagnosis (45, 46).”

    From A deep learning approach for acoustic-based identification of muscle tension dysphonia and spasmodic dysphonia (2026) · cites this paper as [46]

    The Introduction identifies misdiagnosis between ADSD and MTD as a problem, and the Discussion says variability in auditory-perceptual judgments can make listeners unreliable. The paper does not establish that auditory-only discrimination is generally unreliable or that it causes widespread misdiagnosis; it describes listener unreliability as a possibility.

  • Limited SD samples restrict three-class performance and prevent segmentation of SD subtypes (ADSD, ABSD).

    “limited SD samples restrict three-class performance and prevent segmentation of SD subtypes (ADSD, glottal over-adduction; ABSD, glottal under-adduction) (45, 46).”

    From A deep learning approach for acoustic-based identification of muscle tension dysphonia and spasmodic dysphonia (2026) · cites this paper as [46]

    The Participants section reports 36 ADSD and 45 MTD participants, and the diagnostic analysis evaluates those two groups. Our copy does not say that limited SD samples restricted three-class performance or prevented separation of ADSD and ABSD; searches for sample-size limitations and ABSD found no such passage. Page numbers were not available in the indexed passages. (LLM, conf=0.75)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
