What is apraxia of speech?
Childhood apraxia of speech is a motor planning or motor speech disorder that affects a person’s ability to communicate (speak) what they are thinking. It is a disconnect between the brain and the muscles needed to produce speech sounds. It is not muscle weakness but a disconnect between the messaging systems of the brain and the mouth.
CAS has some other names. It is often called verbal dyspraxia or even developmental apraxia. The problem with calling CAS “developmental apraxia” is that developmental speech sound disorders may be outgrown. CAS cannot be outgrown and remediated without intense intervention and therapy.
What is the cause of apraxia of speech?
In most cases, we do not know the cause of CAS. It can be caused by brain trauma such as traumatic brain injury or stroke. It can also be caused by a genetic disorder such as a nervous system syndrome though these causes are not as frequent.
Now that we have more research, we know that CAS can coexist alongside another diagnosis such as autism or developmental delay. It is also important to understand that CAS can cause behavior difficulties and speech problems and language delays. Children with CAS who cannot communicate can show behavior difficulties because they are frustrated and misunderstood.

Characteristics of childhood apraxia of speech
Children with childhood apraxia of speech (CAS) may not have all the symptoms; they may show many or only a few. Know what to look for to be educated on when to seek help in speech delay.
Which children are at risk for apraxia?
Childhood apraxia of speech is often co-occurring or attributed to being a larger part of other conditions such as:
- Cerebral Palsy
- Neuromuscular disorders
Given that apraxia itself is a neurological motor speech condition that often takes longer to diagnose than some of these conditions, it can be a difficult secondary diagnosis to reach. This means educating yourself about the signs of apraxia of speech becomes more important to help your child.
Signs of apraxia of speech: What does it look and sound like?
Children with childhood apraxia of speech may not have all the symptoms; they may show many or only a few. Know what to look for so you are educated on when to seek help.
- Lack of meeting typical speech milestones such as babbling or cooing like a baby or not saying their first word around age ONE
- Difficulty saying a specific set of sounds (not being able to produce only a few sounds)
- Difficulty putting sounds together to make words
- Inconsistencies when saying sounds, such as producing them one day then not being able to produce them the next day
- Feeding problems
- Ability to understand what people are saying but having trouble responding
- Weakness or paralysis of the speech muscles (muscles involved in speech)
- Difficulty imitating (this is a BIG one for therapists, we often identify CAS with this symptom, the inability to imitate) Note: if a child CAN imitate, you may notice that imitation sounds much better than speech produced on their own
- Has low speech intelligibility (they are really hard to understand when they do speak)
- Uses inappropriate stress and intonation when they say words
- Ability to produce shorter words somewhat clearly, but longer words and phrases become very difficult to understand
- Groping while trying to speak (obvious difficulty while the mouth is moving, like they are trying to move their mouth but using too much effort)
- Fine and gross motor difficulties or lack of meeting these typical milestones
How to diagnose childhood apraxia of speech
Because CAS is a communication disorder, a licensed speech-language pathologist is typically the most qualified person to provide assessment and diagnosis. However, it is not uncommon for adjacent professionals such as neurologists, developmental pediatricians, or ABA therapists to refer a child who might be in their care or treatment to an SLP.
From there, an SLP will conduct a proper evaluation and work to connect with appropriate therapists to offer guidance towards their ABA framework. This will vary depending on your child’s age, as there are more finite clues for specific age ranges, including:
18 – 24 months old:
- Delayed onset of speech
- A limited number of spoken words
- Constraints in vowel or consonant formation
2 – 4 years old:
- Voicing errors in similar-sounding words
- Distortion of vowels and consonants
- Difficulty transitioning from word to word
4+ years old:
- Delayed language development
- Difficulty reading and writing
- Sensory processing difficulties
- Chewing/swallowing difficulties
These symptoms can appear or overlap at different age ranges, as no child’s case is the same as another’s. This is why it is critical to get them the proper professional diagnosis and treatment as soon as possible.
Childhood apraxia of speech assessment
Once you have gotten a proper referral to an SLP, they will begin by learning as much as they can about your child’s developmental history and any other known medical issues.
From there, they will conduct a structured assessment that will likely include:
- Interaction with your child to encourage speech, including asking them to repeat syllables, a list of words, or phrases in combination
- Documenting the inventory of sounds that your child can make or the absence thereof, including irregularities or distortions of sounds and words relative to their existing skillset
- An evaluation of your child’s ability to use and understand words, phrases, and grammar in comparison to their age range expectations
- A non-intrusive examination of the mouth, oral structures, and respiratory system
This can be off-putting to many children, especially those with autism, so make sure to let an SLP know if your child is particularly sensitive to physical touch.
- The intention and engagement your child has during communication
An SLP might note whether your child substitutes gestures or points instead of speaking words and phrases they understand but are having trouble articulating.
- A motor speech exam designed to increase the difficulty and dynamic change between words and phrases
The length and complexity difference can push further towards a potential CAS diagnosis once certain characteristics are identified.
It is important to discuss what an evaluation consists of with any SLP before putting your child through them. Your child may have behaviors or sensitivities to some of these actions, and they should be made clear beforehand, so the evaluation goes as smoothly as possible.
How is childhood apraxia of speech treated?
After a comprehensive evaluation with diagnosis and then individualized treatment planning for your child, therapy begins. Therapy starts with simple movements like sounds in isolation or CV (consonant-vowel) words that are developmentally appropriate for the age and then moves to more complex movements that involve multiple syllables and several word phrases.
One specific program often used to treat CAS is the Kaufman Speech to Language Protocol. This approach is backed by science and research and provides servicing therapists with a laid-out program for intervention.
We know that CAS is not a problem with muscle weakness or articulation; it is a dysfunction of motor movements, so we take a motor approach to treatment for apraxia of speech. Muscle memory and motor programming are key! To help the parts of the brain send those messages to the mouth, we have to have repetition – this means lots and lots of practice.
Will my child with apraxia ever talk?
There is no guaranteed outcome of speech for a child with apraxia – but it doesn’t mean things are bleak for a diagnosed child. Many children with childhood apraxia of speech are entirely verbal and have a wide range of communication skills.
Early diagnosis and treatment are critical in giving a child with apraxia the best chance of talking. Proper therapy, working with an SLP, and continued skill practice are all recommended as soon as possible.
How can I help support my child with CAS?
For any child with apraxia, familial support and the proper structure around them can make all the difference. Parental support is even more important for children with autism and apraxia of speech. Find out more on how to help your at home with their language skills here.
The best things you can do to help your child with apraxia are:
- Get a professional diagnosis as early as possible.
- Create a structured treatment plan.
- Provide healthy environments and support groups.
- Use auditory and visual aids if necessary.
- Work with the best SLPs to adjust for growth.
Every child is different, and their needs for treating apraxia will vary. Make sure that you are communicating with your SLP and any other clinicians about potential changes to daily life that might affect your child.
