Discover how Augmentative and Alternative Communication (AAC) strengthens individuals with non-verbal communication support, with the aid of different systems and communication devices under the tailored guidance of Speech Therapists to meet their unique needs.
Have you ever imagined how life-changing a hearing aid can be to a child who struggles to hear the world around them? Just as hearing aids amplify sound, Augmentative and Alternative Communication (AAC) amplifies expression, supporting individuals who find it challenging to communicate what they want or think verbally.
What Does Augmentative and Alternative Communication (AAC) Mean?
AAC refers to the use of systems or communication devices that help individuals with limited speech or communication skills to express their needs and thoughts. Although it receives limited recognition, we use AAC to some extent in our daily lives. It can be as simple as showing a thumbs up, scribbling a note and passing it to another, or nodding your head to give a sign to a friend. When examined more closely, AAC can be understood in two distinct forms:
- Augmentative Communication
Refers to the use of systems or communication tools—such as speech amplifiers—that support or supplement natural speech. - Alternative Communication
Involves the use of systems or devices—such as keyboard-based text-to-speech tools—that replace natural speech when a person is unable to rely on spoken communication.
Notably, both play crucial roles in supporting individuals to communicate effectively by enhancing or replacing natural speech.
Who Can Benefit from AAC Communication?
AAC can support individuals with limited verbal abilities or difficulties in producing or understanding spoken language. Moreover, AAC provides non-verbal communication support for individuals with:
- Autism
- Cerebral palsy
- Speech and language disorders (e.g., aphasia, apraxia)
- Neurodegenerative conditions (e.g., Parkinson’s disease)
- Cognitive impairments (e.g., dementia, brain injury)
- Temporary or long-term speech difficulties following surgeries
- Any condition that affects verbal expression
AAC can be utilised on a temporary or long-term basis, depending on the requirement. For instance, individuals recovering from conditions such as stroke or traumatic brain injury may use it temporarily, whereas those with congenital challenges, autism, and cerebral palsy use it for a longer period to facilitate consistent and meaningful communication.
Types of AAC Communication
AAC can be categorised into two types: unaided and aided communication.
- Unaided AAC- Expressing thoughts and needs without the use of external devices, using an individual’s own gestures, facial expressions, and body movements. This approach is most effective for individuals with adequate motor control.
- Aided AAC- External communication devices and tools, such as communication boards or books with pictures and symbols, alphabet or word boards, cards, writing tools like whiteboards or keyboards, power this method. Aided AAC is further divided into three subcategories based on the level of technology integrated.
- High-tech: Uses digital tools like iPads, computers, or devices with text-to-speech and recorded messages to generate dynamic communication.
- Low-tech: Involves static tools such as picture boards, symbol cards, or communication books with limited customisation.
- Non-tech: Relies on natural methods like written messages, object-based communication, and choice cards.
Most importantly, Speech Therapists ensure AAC devices are tailored to each individual’s abilities and communication goals. They carefully select and organise vocabulary, symbols, and device settings to make communication efficient, meaningful, and user-friendly.
The Real-Life Impact of AAC Communication
AAC plays a crucial role in transforming the lives of individuals with complex communication needs by enabling them to express their thoughts, emotions, and preferences effectively. Several benefits that can be received from AAC can be listed as follows:
- Enhanced self-expression – Enables individuals to express emotions, promoting autonomy and independence.
- Improved social interaction – Facilitates active participation in social settings, helping individuals build relationships and engage confidently in public communication.
- Educational and vocational advancement – Supports effective communication in academic and professional settings, fostering better performance in studies and work.
- Emotional and psychological benefits – Promotes confidence, self-esteem, and a sense of belonging by facilitating better communication through communication tools.
Accordingly, AAC enhances quality of life while ensuring a greater sense of independence, participation, and inclusion in daily communication and social interactions.
Key Takeaways
AAC is utilising communication devices and systems to assist individuals with limited or nonverbal communication abilities. It strengthens them to lead more fulfilling lives by expanding their opportunities for meaningful interaction and self-expression. Therefore, delaying or neglecting non-verbal communication support can hinder communication development, reduce social participation, and limit an individual’s overall quality of life. Speech Therapists play a significant role in supporting them with assessing their needs, selecting the most appropriate communication device, and adjusting it to fit the requirements of the individuals.
