Childhood Apraxia of Speech (CAS) is a motor planning speech disorder. You may also hear CAS referred to as verbal dyspraxia. Children who have CAS are extremely difficult to understand and often start speaking later than their peers. It is very hard for them to use motor planning skills to put sounds into a sequence to create a word. In more severe cases a child may just use a vowel sound or a grunt to attempt to communicate. Children with CAS are often bright and really want to communicate. Many children with CAS will start to use lots of gestures and facial expressions to get their point across.

Many people are surprised to learn that children with CAS are generally able to understand language and know what they want to say. However, their difficulties lie in performing the complex sequenced movements that are needed for their speech to be understood. This means that despite being perfectly willing to participate in a conversation, they are physically unable to do so in an intelligible manner.

In order to be able to speak, a child needs to communicate a message from brain to mouth and voice box. However, a child with CAS will have difficulty planning and coordinating muscle movement for lips, tongue, and voice box as they move from one sound to the next. Their motor plan will often be simplified. For example, they may say “uh uh” for “water,” or “apple.” It is much simpler to say the same syllable two times rather than to change your motor plan for each sound and move from a “w” sound to an “a” sound to a “t” sound to the “er” sound.

The Impact of Childhood Apraxia of Speech

CAS can have a significant impact on many areas of a child’s life, including self-expression, communicating wants and needs, communicating knowledge, and play with peers. In many cases, the inability to speak can impact a child’s safety, or a child’s ability to report to adults when they are in danger. It can also be incredibly frustrating for a child not to be understood by others. In young children, this frustration at not being understood may lead to tantrum behavior. For older children, it may lead to social isolation and depression.

Signs of CAS Every child is a unique individual, and this means that CAS can vary significantly between each child. It is also important to remember that children under three years of age are still learning to speak clearly. As a general rule, unfamiliar listeners (not family members) should understand a 2-year old approximately 50% of the time, a 3-year old 75% of the time, and a 4-year old, 90% of the time.

Below are some red flags for childhood apraxia of speech:

  • A very quiet child who does not babble, or did not babble. *Children should be babbling (sound play--not real words), between 6 months to 12 months. At around 12 months they should be adding real words to their babbling. By the time they are 2 years old, they should be using words more than babbling.

  • Words are not produced the same way every time. One day your child may say a word or sound clearly, and the next day it is produced unclearly or not at all

  • Not understood by anyone most of the time

  • Shorter words are clearer than longer words

  • Struggling with their mouth to get words out

  • Difficulty imitating words or sounds

  • Says only a few words unclearly and is over 2-years old

Some children with CAS also experience difficulties with fine motor skills, delayed language and difficulty with reading, writing and spelling.

How a Speech and Language Pathologist can Help a Child With CAS


The good news is that treatment is available for your child! Speech-Language Pathologists (SLP) are effectively able to assess and diagnose childhood apraxia of speech. The CAS assessment will evaluate how well your child says speech sounds alone and how well the sounds are combined into syllables and words. The SLP will also evaluate how well your child is understood by others in his/her environment.

  • Your child’s treatment plan will target goals based on her/his individual needs. Ultimately, these goals will involve planning the movements needed to say the sounds and learning how to make the movements in the right way at the right time. Often this includes:

  • Multiple repetitions and repeated practice of sound sequences, words, and phrases during a therapy session.

  • Use of visual and tactile (touch) prompting to show how speech sounds are made as sequences of sounds are combined into words.

  • Simultaneous production of sounds— the child copies the therapist or parent.

  • If your child has an extremely restricted range of words or finds it impossible to speak, we can look at creating positive interactions through other communication methods, such as sign language, picture boards and more.
