YOUR QUESTION. A CLEARER NEXT STEP.
What are speech-generating devices?
Speech-generating devices (SGDs) are electronic AAC tools — dedicated devices or tablet apps — that speak aloud the words, symbols or letters a child selects. They give a reliable voice to children who can't rely on natural speech, and evidence shows they support rather than hinder spoken language. The right device is chosen with a speech-language therapist.

When words don't come easily, a device can give a child a powerful, reliable voice.
In short
Speech-generating devices (SGDs) are electronic tools that produce spoken words for a child who cannot rely on natural speech to be understood. A child selects pictures, symbols, words or letters — by touch, by pointing, or even by eye gaze — and the device speaks the message aloud. They are one form of AAC (augmentative and alternative communication), and they support, rather than replace, a child's own developing speech. Far from holding speech back, evidence shows AAC tends to encourage it.
What they look like and how they help
An SGD can be a dedicated communication device or an app running on a tablet. They range widely:
- Simple, single-message buttons — press once to say one phrase ("I want more").
- Grid-based symbol systems — pages of pictures or symbols a child combines into sentences.
- Text-to-speech keyboards — for children who can spell, typing turns into speech.
- Eye-gaze or switch-access devices — for children with significant motor differences, so a look or a single switch press becomes a spoken word.
The right device depends entirely on your child's vision, motor skills, language level and interests — which is why an SGD is chosen with a speech-language therapist, never bought off a shelf and hoped for. A well-matched device reduces frustration, opens up choice-making, and gives a child a dependable way to be heard at home and at school.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Notice how your child already communicates — pointing, leading you by the hand, sounds, gestures. These existing ways of reaching out are exactly what a therapist builds on when matching a speech-generating device.
In everyday life
You don't need to buy anything to begin. Try pairing a few favourite picture cards with the spoken word each time — it builds the link between symbol and meaning that any future device relies on.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
Will a speech-generating device stop my child from learning to talk?
No. This is a common worry, but research consistently shows AAC, including speech-generating devices, tends to encourage natural speech rather than replace it. The device gives your child a reliable way to communicate while spoken language continues to develop.
Is a tablet app the same as a speech-generating device?
It can be. Many speech-generating devices today are apps running on a tablet, while others are dedicated, purpose-built devices. The best choice depends on your child's vision, motor skills and language level, which a speech-language therapist helps assess.
At what age can a child start using a speech-generating device?
There is no fixed minimum age. Even young children can begin with simple single-message buttons or picture-based systems. A therapist matches the device to your child's current abilities rather than to a number.
