Dysarthria

Dysarthria is a speech disorder resulting from weakness and reduced control of the speech and / or breathing muscles. This could result from strokes, Parkinson's disease, brain injuries, dementia, head and neck cancers, and progressive neurological disorders (e.g. multiple sclerosis). These difficulties are often treated with exercises to improve oro-motor function and speech intelligibility.

Individuals with dysarthria may have:

  • Slurred Speech
  • Soft, breathy, hoarse voice
  • Abnormal intonation
  • Abnormal rhythm (too fast / too slow)
  • Difficulty being understood by others

Voice therapy helps individuals improve vocal loudness and vocal quality in a safe and efficient manner.
