High-tech AAC

Also called Electronic AAC, Powered communication aid, AAC app

Devices and apps that speak. What they add over paper, and what they cost you in setup, charging and someone to look after them.

What it is

High-tech AAC is any communication aid that needs power: a tablet running a communication app, a dedicated speech-generating device, a laptop with an eye-tracker, a single recorded-message button. The defining feature is speech output. The device says the words, so the person can talk to someone who is not looking, is across the room, or is on the phone.

It is a category, not a level. A £30 recordable button and a £10,000 eye-gaze system are both high-tech. What separates them is what the person needs, not how advanced they are.

Who it can help

People who need to be heard by strangers, at a distance, or without a partner leaning in. People who want to speak for themselves in a meeting, order in a café, or argue with their sister. Anyone whose motor access is easier on a screen than on paper, including people who use eye gaze or switch scanning, for whom a device is the only practical route to a full vocabulary.

Honestly, it is not the right first step for everyone. Someone who has never used symbols is often better served by a paper board for a few weeks, because the device adds charging, updates, breakage and settings on top of the work of learning the words. And no device replaces a partner who models.

How it works

The person selects a cell (a symbol, word or letter) by touch, switch, eye or head movement. Selections collect on a sentence strip. A tap speaks the strip using text-to-speech, in a synthetic voice the person has chosen, or in recorded speech, or in their own banked voice.

Underneath sits a page set, the complete vocabulary and how it is laid out, which is the real product. Two devices with the same hardware and different page sets are different communication systems. Most apps also add word prediction, quick phrases and settings for touch and scanning.

Getting started

Try before you spend. The Talk board is free, needs no account, works offline once loaded and runs on a phone, tablet or laptop you already own. It speaks with the voices already on the device and lets the person choose the voice, its speed and its pitch. If a person takes to it, you have learned something a supplier would charge to find out.

Decide who owns the setup. Every high-tech system needs one named person who charges it, backs it up, adds words and knows the settings. Without that person, devices die quietly.

Ask for a device loan before any purchase or funding application. Most local AAC services and suppliers lend for a few weeks.

Where to get help

A speech and language therapist is the NHS route, and complex cases go to a regional specialised AAC service, which assesses and provides equipment free in England. Communication Matters lists suppliers and runs a national conference where every device can be tried in one room. ACE Centre publishes independent guides to apps and devices.
