AI could transform communication for people with disabilities

More than 4 million people worldwide rely on Augmentative and Alternative Communication (AAC) devices to communicate, yet many report that current technology is slow, limited, and impersonal (WHO). People with disabilities who cannot communicate easily through speech increasingly rely on technology to interact with others and manage daily tasks. Augmentative and Alternative Communication (AAC) devices are central to this effort, offering solutions that range from low-tech tools like picture boards to advanced speech-generating devices.

Augmentative and Alternative Communication (AAC) refers to methods and devices that support or replace speech for individuals with communication challenges. Modern AAC systems allow users to select pre-programmed phrases, generate speech via artificial voices, control apps, and operate smart devices within the home. These technologies aim to provide autonomy, social engagement, and independence for people with diverse physical and cognitive abilities.

Common challenges and needs

Despite their potential, many AAC devices remain slow and difficult to use. Users frequently request:

- Longer battery life to allow continuous use throughout the day

- Faster interfaces that more closely match the speed of natural conversation

- Integration with home and work environments to support independence

- More intuitive and adaptive features that reduce cognitive load

These needs highlight a gap between current technology and the possibilities that AI could unlock.

The role of AI in AAC

Artificial intelligence (AI) is increasingly being incorporated into AAC devices to enhance performance and personalization. AI can predict commonly used phrases, correct typing errors, and suggest shortcuts to accelerate communication. Voice synthesis technologies now allow devices to produce artificial voices that reflect users’ age, regional accent, and personality, helping individuals maintain a sense of identity while communicating.

Dougal Hawes, CEO of Smartbox, told delegates that AI could correct typing, suggest faster ways to communicate, and even clone voices to reflect a user’s age, accent, and personality.

AI also enables creative applications, such as translating user input into musical or artistic outputs, providing broader participation in cultural or leisure activities. Experts anticipate that as AI continues to evolve, AAC devices will become faster, more responsive, and more closely aligned with the needs of users.

Future directions

The development of AAC is shifting toward highly personalized, adaptive systems. Future devices are expected to be faster, easier to use, and capable of integrating AI-driven features that enhance autonomy and quality of life. Researchers and developers are focused on making technology that not only restores communication but also expands opportunities for independence, learning, and creative expression.
