Dysarthria: strategies for clearer speech

Dysarthria is slurred or hard-to-understand speech from weak or poorly controlled muscles. Practical ways to be understood - for the speaker and the listener.

Dysarthria is speech that is hard to understand because the muscles for talking are weak, slow, or poorly coordinated - after a stroke, brain injury, or in conditions like Parkinson’s. The words and language are intact; the delivery is the challenge.

For the speaker

  • Slow down. This is the single most helpful change - it gives muscles time.
  • Say it in shorter chunks. Pause between phrases and take a breath.
  • Over-articulate. Exaggerate the mouth movements a little; “punch” key words.
  • Be loud enough. A stronger breath and voice carry the words (see also LSVT LOUD for Parkinson’s).
  • Face the listener in good light so they can see your mouth.
  • Have a back-up. Keep a pen, a phone, or an alphabet board for tricky moments.

For the listener

  • Give your full attention and reduce background noise.
  • Watch the person’s face and gestures, not just the sounds.
  • Repeat back what you understood so they only fix the gap.
  • Don’t pretend to understand - it’s kinder to ask than to guess wrong.
  • Allow plenty of time; don’t finish their sentences unless invited.

When to get help

A speech therapist can assess which muscles are involved and tailor exercises, pacing, and (if needed) communication aids. Clear speech is a skill that improves with the right, regular practice.
