What Is AAC?
Augmentative and Alternative Communication (AAC) refers to all forms of communication—other than spoken words—that are used to express thoughts, needs, wants and ideas. AAC helps individuals who have difficulty speaking or are unable to speak at all, whether temporarily or permanently.
AAC can augment spoken language (supporting speech) or serve as an alternative when speech is not functional or reliable.
AAC is for people of all ages and abilities—and it’s about giving everyone a voice.
Who Might Benefit from AAC?
AAC can support communication for individuals with a variety of conditions, including:
- Autism spectrum disorder (ASD)
- Cerebral palsy
- Down syndrome
- Apraxia of speech
- Stroke or brain injury
- ALS or other degenerative diseases
- Developmental delays or genetic syndromes
- Temporary loss of speech due to surgery, illness or trauma
AAC can be a life-changing tool for connection and independence.
Types of AAC
AAC can range from low-tech tools to high-tech devices:
No-Tech or Low-Tech AAC
- Gestures and facial expressions
- Sign language
- Picture exchange systems (e.g., PECS)
- Communication boards or books
High-Tech AAC
- Speech-generating devices (SGDs)
- AAC apps on tablets or dedicated devices
- Eye-tracking or switch-accessible communication systems
The best AAC system is the one that matches the individual’s needs, abilities, environment and goals—and this can change over time.
Our Approach to AAC
At the Center for Hearing and Speech, our licensed Speech-Language Pathologists (SLPs) work with individuals and families to:
- Assess communication needs and abilities
- Trial AAC systems to find the best fit
- Train users, families, and caregivers on using AAC in daily life
- Collaborate with schools, therapists and assistive tech providers
- Support AAC users in building confidence, independence and authentic communication
AAC isn’t just about requesting needs—it’s about building real connections, expressing opinions, telling stories and being heard.
When To Seek AAC Support
You may want to explore AAC options if:
- A child is not speaking or using very few words beyond age expectations
- Speech is unreliable, unclear or effortful
- A medical condition has caused a loss of speech
- Traditional speech therapy hasn’t led to effective verbal communication
- There is frustration or behavioral difficulty linked to communication barriers
AAC can be introduced at any age, including early childhood. It does not prevent or delay speech development; in fact, it often supports it.
