What are the most common types of Speech Disorder?

29 Jul, 2021

Many people can identify one or few types of speech disorders, but speech therapists treat many kinds of conditions in reality. Some speech disorders are present at birth, while others develop with time.

Some may stem from a disability or an injury, while others are due to neurological function. Regardless of the root cause, speech therapy can improve the quality of life for most patients.

Causes of Speech Disorders

Speech disorders affect nerves, muscles, vocal cords, and other parts within the throat. What causes these speech disorders?

  • Brain damage
  • Strokes
  • Vocal cord paralysis
  • Strokes
  • Weak muscles
  • Polyps on the vocal cords



In some cases, speech disorders occur in people with medical conditions such as;

  • Oral cancer
  • Autism
  • Dementia
  • Laryngeal cancer
  • Strokes
  • Attention-deficit/hyperactivity disorder

It is also worth noting that speech disorders can be hereditary and they develop over time.

Common Types of Speech Disorders

At Gen Physio, we encounter patients with various forms of speech problems. Below are some of the disorders we can help treat:


Stuttering comes in different forms, including long pauses, repetitions, and prolongations. This fluency disorder is common in cases of excitement or nervousness. Individuals with this speech problem may feel tense and tend to avoid words or situations that may trigger stuttering. Other secondary physical behaviours include jaw tightening and excess eye blinking.

Attention-deficit/Hyperactivity Disorder Symptoms (ADHD)

ADHD is a chronic condition that makes it hard for people to control their behaviour or pay attention, leading to communication problems. Some people with ADHD may not be hyperactive, but those who do experience problems staying still. Individuals with ADHD may experience aggression, hyperactivity, forgetfulness, and different mood swings.

Childhood Apraxia of Speech

A person with childhood apraxia of speech experiences difficulties stringing sounds correctly to make a word. It occurs because the brain experiences problems in movement coordination. 


Dysarthria is a brain injury-related speech disorder that occurs when muscles in the tongue, lips, or jaws are too weak to form words properly.

Resonance Disorders

A resonance disorder is caused by airflow blockage in the throat, mouth, or nose, affecting voice quality vibrations. The leading causes of this disorder are swollen tonsils and cleft palate.
