About Dysarthria

We use many muscles to talk. These include muscles in our face, lips, tongue, and throat, as well as muscles for breathing. It is harder to talk when these muscles are weak. Dysarthria happens when you have weak muscles due to brain damage. It is a motor speech disorder and can be mild or severe.

Dysarthria can happen with other speech and language problems. You might have trouble getting messages from your brain to your muscles to make them move, called apraxia. You could also have trouble understanding what others say or telling others about your thoughts, called aphasia.

Signs of Dysarthria

If you have dysarthria you may:

  • Have "slurred" or "mumbled" speech that can be hard to understand.

  • Speak slowly.

  • Talk too fast.

  • Speak softly.

  • Not be able to move your tongue, lips, and jaw very well.

  • Sound robotic or choppy.

  • Have changes in your voice. You may sound hoarse or breathy. Or, you may sound like you have a stuffy nose or are talking out of your nose.

Brain damage causes dysarthria. It can happen at birth or after an illness or injury. Anything that causes brain damage can cause dysarthria, such as:

  • Stroke

  • Amyotrophic lateral sclerosis, or ALS

  • Huntington's disease

She will listen to your speech in single words, sentences, and conversation. The SLP will test how well you understand and talk.
