Augmentative and Alternative Communication (AAC)

Speaking is only one way to communicate.

You may already use gestures, facial expressions, writing things down, pictures, signs or technology to help get your message across. You may be exploring options for yourself, supporting a partner or family member, or wondering whether communication could feel easier in everyday life.

AAC stands for Augmentative and Alternative Communication. It describes different ways people can communicate alongside speech or instead of speech.

AAC is not one single system. It is not only for people who do not speak. Different approaches work for different people.

The aim is not to replace someone’s voice or communication style. It is about finding what works for the person.

Everyone communicates differently.

People may notice:

• speaking takes a lot of effort
• speech changes during the day or becomes less reliable when tired
• getting messages across feels easier with pictures, writing or technology
• frustration when other people guess or speak for someone
• avoiding situations because communication feels hard work
• wanting more independence in daily life
• family members feeling unsure how best to support communication

Partners, family members and carers sometimes notice they are doing a lot of interpreting or speaking on someone’s behalf and wonder if there could be easier ways to communicate together.

The people and environment around someone can make a big difference too. Noise, pace, interruptions and time pressure can all affect communication.

How speech and language therapists can help

Speech and language therapists work with people and families to understand what makes communication easier.

Support may include:

• understanding strengths and preferences
• exploring communication tools and options
• trying different supports, from paper based systems to apps and specialist devices
• adapting routines and reducing communication pressure
• helping communication work better at home, work and socially
• supporting family members, carers and people around the person
• working with other professionals where needed

Support is not only about finding a communication system. Small changes from the people around someone can make a real difference too.
