Area of Science:

  • Speech motor control
  • Neurolinguistics
  • Articulatory phonetics

Background:

  • Articulatory discoordination is a proposed hallmark of dysarthria.
  • Experimental evidence specifying these coordination difficulties is limited.

Purpose of the Study:

  • To evaluate labial-lingual gesture coordination for /u/ production in dysarthria.
  • To compare coordination patterns in Parkinson's disease (PD) and amyotrophic lateral sclerosis (ALS) with controls.

Main Methods:

  • Utilized X-ray microbeam data to track tongue and lip movements.
  • Inferred articulatory gesture timing relative to acoustic targets for /u/.
  • Analyzed synchronization and scaling of gestures in PD, ALS, and control participants.

Related Experiment Videos

Main Results:

  • Articulatory gestures for /u/ were synchronized and predictive of acoustic targets across all groups.
  • Coordination patterns were generally similar between controls and individuals with dysarthria.
  • Synchronization was less defined and more variable in speakers with ALS compared to PD and controls.

Conclusions:

  • The fundamental synchronization of articulatory gestures is preserved in dysarthria.
  • Variability in coordination may differ between subtypes of dysarthria (e.g., ALS vs. PD).
  • Findings inform our understanding of speech production mechanisms in neurological disorders.
