The technology that gave Stephen Hawking a voice should be accessible to all who need it

Stephen Hawking was one of the most prominent people in history to use a high-tech communication aid known as augmentative and alternative communication (AAC).
His death comes in the year of the 70th Anniversary of the Declaration of Human Rights. Over the course of his adult life, Hawking came to represent the epitome of what effective communication with AAC systems really means: gaining access to the human right of communication enshrined in Article 19 of the Universal Declaration of Human Rights.
Today, many Australians who need AAC still lack access to the technology and the support they need to use it. It’s time for that to change.
How augmentative and alternative communication works
To most people who can speak, AAC systems are a bit of a mystery – it’s not always clear how the person using it is controlling the system. Indeed, people’s fascination with how a speech device works often overtakes their attention to what the person is actually saying.
AAC includes sign and gesture systems, communication boards, speech-generating devices, mobile phones with apps, and even emojis and social media. Ultimately it works not only through the interaction of the user with their device, but also through their interactions with communication partners.
Some types of AAC don’t involve technology at all, but use the person’s body, such as sign or gesture systems. Some AAC systems are non-electronic, like communication boards, books, or wallets for people to point to or look at letters, words or phrases to communicate. Other types of AAC are known as “high-tech”, in that they involve electronic systems and computer-based technologies to both store and retrieve words for communication.
Apart from the time taken to compose a message, it can take hours to program what could be spoken using a communication aid – and many more to ensure that the desired words can be found just in time for communication.
Hawking used a switch to control software on a computer that enabled him to talk. This kind of switch allows users to scan through options shown on the screen until they reach the letter, word or message to select for the device to “speak”.
Realising the potential of people with communication disability
Hawking did not tend to use his platform in relation to disability, but when he did his words were significant. In writing the foreword to the World Report on Disability in 2011, he highlighted the importance of people with disability having access to the equipment that they need, saying:
…we have a moral duty to remove the barriers to participation, and to invest sufficient funding and expertise to unlock the vast potential of people with disabilities.
A patron of the Motor Neurone Disease Association, Hawking inspired millions of people around the world with the condition. His lifetime achievement as a person who uses AAC was recognised by the International Society for Augmentative and Alternative Communication.
