Dysarthria is a motor speech disorder resulting from neurological injury of the motor component of the motor-speech system and is characterized by poor articulation of phonemes. In other words, it is a situation in which problems effectively occur with the muscles that help produce speech, often making it very difficult to pronounce words.

Individuals with dysarthria may experience challenges in the following:

• Tone.
• Steadiness.
• Speed.
• Volume.
• Vocal quality.
• Timing.
• Pitch.
• Breathe control.
• Strength.
• Range.
