Apraxia of Speech

Apraxia of Speech (AOS) is a speech disorder resulting from damage to parts of the brain that are used for planning, forming and sequencing sounds into speech. This commonly results from strokes or brain injury.

Individuals with AOS often have:

  • Difficulty imitating speech sounds / non-speech movements (e.g. sticking out tongue)
  • Difficulty finding the correct mouth positions to make / coordinate sounds
  • Trouble sequencing sounds & words
  • Inconsistent speech errors and increasing errors with longer phrases
