Patterns of lung volume use during an extemporaneous speech task in persons with Parkinson disease
Abstract
Unlabelled This study examined patterns of lung volume use in speakers with Parkinson disease (PD) during an extemporaneous speaking task. The performance of a control group was also examined. Behaviors described are based on acoustic, kinematic and linguistic measures. Group differences were found in breath group duration, lung volume initiation, and lung volume termination measures. Speakers in the control group alternated between a longer and shorter breath groups. With starting lung volumes being higher for the longer breath groups and lower for shorter breath groups. Speech production was terminated before reaching tidal end expiratory level. This pattern was also seen in 4 of 7 speakers with PD. The remaining 3 PD speakers initiated speech at low starting lung volumes and continued speaking below EEL. This subgroup of PD speakers ended breath groups at agrammatical boundaries, whereas control speakers ended at appropriate grammatical boundaries. Learning outcomes As a result of participating in this exercise, the reader will (1) be able to describe the patterns of lung volume use in speakers with Parkinson disease and compare them with those employed by control speakers; and (2) obtain information about the influence of speaking task on speech breathing.

Other studies have shown that speakers with Parkinson's disease initiate and terminate speech at lower-than-normal lung volumes.
“In contrast, other studies have shown that speakers with PD initiate and terminate speech at lower-than-normal lung volumes (Bunton, 2005; Darling-White et al., 2022; Huber & Darling-White, 2017).”

Physiological changes in Parkinson's disease may adversely affect the efficiency of rest breathing and speech breathing.
“These physiological changes may adversely affect the efficiency of rest breathing (Tzelepis et al., 1988) and speech breathing (Bunton, 2005; Huber et al., 2003) in persons with PD.”

The variability in speech breathing patterns used to support louder speech, as reflected in Figure 2 and Table 4, is consistent with prior studies of persons with PD and healthy young adults.
“Last, the authors would like to note that the variability in speech breathing patterns used to support louder speech, as reflected in Figure 2 and Table 4, is consistent with prior studies of persons with PD (Bunton, 2005; Huber et al., 2003; Stathopoulos et al., 2014) and healthy young adults (Stathopoulos & Sapienza, 1993).”

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.
