Important Notice: This content is for educational purposes only and is not medical advice. Little Wheels is not a medical service. Childhood Apraxia of Speech requires professional diagnosis and treatment. If you have concerns about your child's speech development, consult your pediatrician or a speech-language pathologist with specialized CAS training for proper evaluation and guidance.
Developmental Disclaimer: We cannot and do not provide diagnoses or determine whether a child has apraxia, speech delays, or other developmental differences. Only qualified professionals can make these assessments through proper evaluation.
When your child understands everything you say but struggles to speak—when they can say a word one day but not the next, or when you see them physically struggling to position their mouth—you might be facing Childhood Apraxia of Speech (CAS).
As a parent myself, I know how frightening it is to suspect something more complex than typical speech delay. When building the Talk & Listen app, I researched CAS extensively to understand how motor planning differs from articulation. I consulted with SLPs who specialize in apraxia and evaluated which resources provide accurate, parent-friendly information about this rare disorder.
Where should parents find trusted apraxia information?
Start with specialist clinics that focus on CAS treatment: NAPA Center (intensive therapy programs), Children's Hospital of Philadelphia, Johns Hopkins, and SLP practices with PROMPT or DTTC certification. These provide evidence-based information on motor learning approaches. Avoid general speech resources—CAS requires specialized treatment that differs from typical speech therapy.
This guide curates the most reliable CAS resources I've found—from internationally recognized intensive therapy centers to local specialists with evidence-based training. Every source is written by or affiliated with credentialed SLPs who specialize in motor speech disorders.
What is Childhood Apraxia of Speech?
Childhood Apraxia of Speech is a neurological motor speech disorder where the brain has difficulty coordinating the precise, rapid movements needed for speech. It's not muscle weakness—the muscles work fine. It's a motor planning problem.
Key Characteristics
- Inconsistent errors: Child says "mama" one day but can't say it the next
- Articulatory groping: Visible struggle to position mouth, tongue, lips
- Understanding exceeds production: Child comprehends language but can't speak it
- Difficulty with sequences: Struggles with longer words or phrases
- Prosody issues: Unusual rhythm, stress, or intonation patterns
Critical to understand: Children with CAS will not outgrow it without intervention. Unlike typical speech delays where children often catch up naturally, CAS requires specialized speech therapy using motor learning principles.
Prevalence: CAS affects approximately 1-2 out of every 1,000 children, making it relatively rare. This rarity means many general SLPs have limited CAS experience—seek specialists with specific CAS training.
National Intensive Therapy Centers
For families seeking intensive treatment, these centers offer specialized CAS programs. Many families travel from across the country (and internationally) for their expertise.

Evidence-Based Treatment Approaches
CAS requires specialized treatment approaches that differ from traditional speech therapy. The most researched, evidence-based methods are PROMPT and DTTC.
PROMPT (Prompts for Restructuring Oral Muscular Phonetic Targets)
What it is: Tactile-kinesthetic approach using touch cues to manually guide word production for jaw, tongue, and lips. SLP uses hands-on cues on the child's face and neck to help them feel the correct movements.
Who it helps: Tactile learners, children who benefit from physical guidance, moderate to severe CAS.
Where to find PROMPT therapists:
- Speech in The City (New York, NY): PROMPT-certified practice; all clinicians PROMPT trained
PROMPT and DTTC Treatment Approaches - Family First Therapy Inc (Tampa, FL): PROMPT-trained speech therapists
DTTC & PROMPT Therapy - Sensory Kids & Social Minds (Multi-state): Motor speech-trained SLPs; PROMPT and DTTC specialists
PROMPT Therapy
DTTC (Dynamic Temporal and Tactile Cueing)
What it is: Uses auditory, visual, or tactile cues for imitation with hierarchical fading of support. Focuses on simultaneous production, direct imitation, and gradual reduction of cues as child gains independence.
Who it helps: Children able to follow cognitive directives, those who respond well to imitation-based practice.
Where to find DTTC therapists:
- Ridge Zeller Therapy (Chandler, AZ): Team specifically trained in CAS; uses evidence-based DTTC
Apraxia of Speech (CAS) - Total Speech Therapy (Multi-state in-home): Travels to patients' homes; DTTC with immediate frequent feedback

Frequently Asked Questions About Childhood Apraxia of Speech
Southwest Region
Sol Speech & Language Therapy (Austin & Round Rock, TX)
Phone: (512) 368-9488 | Services: In-clinic and telehealth
Best age-specific symptom breakdown. Explains CAS as brain struggling to coordinate speech movements (not muscle weakness). Provides detailed signs by age:
- 18-24 months: Limited consonants/vowels, minimal babbling, difficulty imitating
- 2-4 years: Vowel errors, inconsistent errors, groping, prosody issues
Critical message: Early intervention critical; speech therapy required (won't dissipate naturally). Distinguishes CAS from articulation disorder and dysarthria.
When to Seek Professional Evaluation
CAS requires specialized diagnosis by a speech-language pathologist with CAS training. Seek evaluation if you notice:
Early Warning Signs (18-24 months)
- Limited babbling or very quiet baby
- Limited consonants and vowels in attempts to speak
- Difficulty imitating sounds or words
- Understanding is much better than speech production
Red Flags (2-4 years)
- Inconsistent errors (says a word correctly sometimes, incorrectly other times)
- Articulatory groping (visible struggle to position mouth)
- Vowel errors (not just consonant errors)
- Difficulty with longer words or phrases
- Unusual rhythm, stress, or intonation (prosody issues)
- Frustration with communication attempts
How to Find a CAS Specialist
Look for SLPs with:
- PROMPT certification or training
- DTTC training or certification
- Specific CAS experience (ask how many CAS cases they've treated)
- Motor speech disorder specialization
ASHA ProFind: Search for SLPs and filter by "Childhood Apraxia of Speech" specialty
https://find.asha.org/Important: Not all SLPs have CAS training. General speech therapists may not recognize CAS or may use approaches that aren't effective for motor planning disorders. Seek specialists with specific CAS credentials.
Expected treatment frequency: Most CAS specialists recommend 3-5 sessions per week initially. This is significantly more frequent than typical speech therapy (1-2x/week) because motor learning requires high-frequency practice.
A Note About Little Wheels and CAS
The Talk & Listen app was designed for typical speech development and common phonological processes—not specifically for CAS. While some SLPs use it as a supplemental tool for home practice with CAS clients, it does not replace specialized CAS therapy.
Why CAS Requires Specialized Treatment
CAS is a motor planning disorder, not an articulation disorder. Children with CAS need:
- Tactile/kinesthetic cues (PROMPT, DTTC)
- Immediate, specific feedback on movement accuracy
- High-frequency practice (3-5x/week minimum)
- Focus on whole-word movements, not isolated sounds
- Motor learning principles (blocked vs. random practice, fading cues)
If your child has CAS: Work with a PROMPT or DTTC-trained SLP as your primary intervention. Apps like Talk & Listen can supplement therapy for home practice, but only under SLP guidance and only if appropriate for your child's specific needs.
