Aac
What is AAC (augmentative and alternative communication)?
AAC (augmentative and alternative communication) is the full range of methods — from gestures, sign and picture cards to speech-generating apps and devices — that help a child communicate when speech is delayed or limited. It adds to or offers an alternative to talking, and the evidence shows it supports rather than holds back spoken language.
When words alone aren't enough, AAC gives your child another way to say what they mean — and to be truly heard.
In short
AAC stands for augmentative and alternative communication — the whole toolkit of methods that help a child communicate when speech is delayed, limited or hard to understand. Augmentative means it adds to whatever speech a child has; alternative means it offers another route entirely. AAC can be as simple as gestures, sign and picture cards, or as advanced as a speech-generating device or tablet app that 'speaks' when a child taps a symbol. It does not replace talking or hold speech back — research consistently shows it supports communication and often encourages spoken language to grow.How AAC works
AAC ranges across a spectrum, and most children use a blend that changes over time:- No-tech / unaided — gestures, body language, facial expression, eye-gaze and sign.
- Low-tech — picture cards, communication boards, photo books, symbol charts.
- High-tech — tablet apps and dedicated speech-generating devices that produce spoken output from symbols or text.
It helps children who are minimally verbal, autistic, have cerebral palsy, apraxia of speech, Down syndrome or other complex communication needs. The goal is always the same: give the child a reliable, immediate way to make requests, refuse, comment, ask questions and connect — so that frustration falls and relationships flourish.
A common worry, answered
Many parents fear that giving a device means "giving up" on speech. The evidence points the other way: AAC reduces the pressure to perform, models language visually, and frequently sits alongside speech therapy as a bridge — not a destination. Communication of any kind is the foundation everything else is built on.The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an app or an online form.

What to watch
Notice how your child already communicates — pointing, leading you by the hand, eye-gaze, sounds or gestures. These existing signals are the natural foundation a speech therapist builds AAC upon.
Try this at home
Try simple picture cards for favourite snacks or activities, and model using them yourself by pointing to a card as you say the word. Children learn AAC best by watching trusted adults use it too.

Frequently asked
Will using AAC stop my child from learning to talk?
No. Research consistently shows AAC does not hold back speech — it often encourages spoken language by easing the pressure to talk and showing children that communication works. Many children use AAC alongside speech therapy and develop more words over time.
What are the different types of AAC?
AAC ranges from no-tech methods like gestures, sign and eye-gaze, to low-tech tools such as picture cards and communication boards, to high-tech tablet apps and speech-generating devices. Most children use a flexible blend that changes as they grow.
Which children benefit from AAC?
AAC helps children who are minimally verbal or whose speech is hard to understand — including many autistic children and those with cerebral palsy, apraxia of speech, Down syndrome or other complex communication needs. A speech-language therapist matches the right approach to each child.
