Specific acoustic and discourse markers of Alzheimer's disease in English speakers may generalize onto Spanish speakers, and dysarthric aspects that typify Parkinson's disease and its phenotypes seem similar across the languages studied so far.
“Moreover, specific acoustic and discourse markers of Alzheimer's disease in English speakers may generalize onto Spanish speak ers, 88 and dysarthric aspects that typify Parkinson's disease 89 and its phenotypes 20,69,90 seem similar across the languages studied so far.”

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.
