What is dysarthria?

Motor speech disorders are called dysarthrias. Some dysarthrias can cause words to slur. A person's speech might be slow. Vowel sounds could be distorted or speakers might have problems varying their tone. The speaking pattern that can result, particularly when there are long pauses between words or syllables, has its own term: scanning speech.

Dysarthria is a speech impairment caused by an underlying motor condition. People with dysarthia can't properly control the muscles needed for speech. This causes speech to become slurred or distorted, making it hard to understand. Dysarthria can be caused by a variety of things, including stroke, brain injury, or even certain medications. All of these things may affect your ability to control and coordinate the muscles used to produce speech, which causes dysarthria.

Dysarthria is diagnosed when there is a speech dysfunction with slurring or inability to pronounce words clearly,even though one can understand speech and form proper words in one’s mind,. The condition is caused by an injury to the brain centers that control the movement of the tongue, palate, and lips. Speech may be slow or slurred, and one side of the face may droop because the facial muscles are paralyzed. Drooling may also occur. Persons with dysarthria often can write their thoughts down even though they cannot speak them out loud.
