There is more than one way to model communication: Using speech prompts, signs, and AAC together in therapy

One of the most important things I have learned as a paediatric speech and language therapist is this:
Children do not all learn communication in the same way.
Some children learn best through listening.
Some need visual support.
Some need movement and gesture.
Some benefit from symbols or technology.
And many children need multiple supports together before communication truly starts to develop.
That is why flexible, responsive therapy matters so much.
In this short therapy clip, I model just two simple words:
‘Go’ and ‘Up’.
But underneath those tiny moments is a combination of therapeutic strategies:
- speech sound prompting
- visual cueing
- Makaton signing
- AAC (Augmentative and Alternative Communication) modelling
- repetition
- motor planning support
- language modelling
- total communication principles.
Communication is bigger than speech alone
One of the biggest misconceptions about speech therapy is the idea that communication only ‘counts’ if a child says the word verbally.
In reality, communication comes in many forms:
- speech
- gesture
- facial expression
- signing
- pointing
- symbols
- body language
- AAC.
This is particularly true for children with:
- developmental language disorder (DLD)
- autism
- motor speech difficulties
- childhood apraxia of speech (CAS)
- phonological difficulties
- global developmental delay
- complex communication needs.
These children often need communication to be presented through multiple pathways at once.
That is where total communication approaches become so powerful.
This is important to know: this does not confuse children. In fact, for many children, it does the opposite. It creates clarity.
Careful sound prompting helps bridge that gap.
Research and clinical experience consistently show that signs often support spoken language development rather than hinder it.
Research suggests that learning signs alongside spoken language does not hinder speech development and may support overall language acquisition, communication confidence, and vocabulary growth in many children.
For many children, signs actually help speech emerge because they:
- reduce communication pressure
- build confidence
- strengthen understanding of words.
A child who can successfully communicate is far more likely to keep attempting interaction.
The power of AAC and LAMP Words for Life
In the clip, I also model language using an electronic AAC system: LAMP Words for Life.
AAC stands for Augmentative and Alternative Communication.
AAC includes any tool that supports communication beyond speech alone, including:
- picture systems
- symbol boards
- communication books
- speech-generating devices.
LAMP Words for Life is one of my favourite AAC systems because it focuses on consistent motor patterns and meaningful language development. Because communication is not about achieving perfection. It is about connection.
And when children are given multiple ways to express themselves, they often become more confident, more engaged, and more willing to interact with the world around them.
That is the true power of total communication therapy.
