DTTC for Childhood Apraxia of Speech: How the Cueing Hierarchy Works
DTTC is a motor-based treatment for childhood apraxia of speech built around one idea: fade your support gradually rather than all at once. You start by saying the word together, and step back one level at a time as your child succeeds. Our apraxia module implements that hierarchy directly, with around 91 targets organised by syllable shape.

Who this is for
- Parents of a child diagnosed with, or being assessed for, apraxia of speech
- Families told their child needs "motor speech" practice and given little detail on what that means at home
- Anyone whose child can say a word one minute and not the next — the pattern that most distinguishes apraxia
- SLPs who want a home-practice tool that follows the same hierarchy they use in session
What does DTTC actually stand for, and why does it matter?
DTTC stands for Dynamic Temporal and Tactile Cueing. It was developed by Edythe Strand for children whose difficulty is planning and sequencing the movements of speech rather than knowing the word or having weak muscles. "Dynamic" is the important part: the amount of help you give changes constantly, based on what the child just did.
That distinction matters because apraxia does not respond well to the drilling that suits articulation errors. A child with apraxia often knows exactly what they want to say and can produce a sound in one word but not another. Practising the sound in isolation, over and over, tends not to transfer. What does help is practising whole movement sequences — real words — many times, with support that fades as the child gets steadier.
What are the five cueing levels in DTTC?
The hierarchy moves from maximum support to none, and our apraxia module records which level each attempt was made at, so progress is visible rather than guessed.
Simultaneous — you and your child say the word together, at the same time, slowly. Immediate — you say the word, and your child repeats it straight away. Delayed — you say the word, then pause a second or two before your child says it, which forces them to hold the plan in mind. Faded — you give only a partial cue, perhaps mouthing the first sound. Independent — your child produces the word with no model at all, ideally in a real exchange.
The rule is to move down a level after a run of successes, and back up immediately after failures rather than letting your child struggle. Struggling repeats the wrong motor plan, which is the opposite of what you want.
Why are targets grouped by syllable shape rather than by sound?
Because in apraxia the difficulty lives in the transitions between sounds, not in the sounds themselves. A child may manage "bee" (CV — consonant then vowel) but not "beep" (CVC), because closing the syllable adds a movement to sequence.
Our targets are organised across five syllable structures, from simple CV and VC shapes up to CVC and longer, multisyllabic words. Starting at the shape your child can already manage and adding complexity one step at a time is far more productive than starting with words that matter emotionally but are structurally hard.
Targets are also grouped by category — functional words, animals, food, actions, people — so practice can stay on words your child has a genuine reason to say. A word they actually want tends to be practised more.
What is the difference between blocked and random practice?
Blocked practice means many repetitions of one target before moving on. Random practice means mixing targets up within a session. Both are available in the module, and the order matters.
Blocked practice helps when a movement is new — the repetition establishes the plan. But motor-learning research consistently finds that blocked practice flatters performance during the session while producing weaker retention afterwards. Random practice feels harder and looks worse in the moment, then holds up better a week later.
A practical pattern many SLPs use: blocked practice while a target is being acquired, then switching to random once the child is getting it right most of the time. If practice looks suspiciously perfect, that is usually a sign to make it harder, not a sign to celebrate.
How much practice does DTTC actually need?
Motor learning depends on the number of correct productions, so frequency matters more than session length. Short daily practice generally beats one long weekly session, and this is precisely where home practice adds something a clinic appointment cannot.
That said, be realistic. A tired or resistant child produces little of value, and pushing through a bad session can make the whole activity aversive. Several short sessions across a day, stopping while it is still going well, is a better pattern than one long effort.
This is support for practice between sessions, not a replacement for a speech-language pathologist. Apraxia needs a proper differential diagnosis — several other things look similar — and an SLP should set the targets and the cueing level. If yours does, they can connect to the same account so their goals appear directly in your practice.
