One of the biggest concerns parents have about Augmentative and Alternative Communication (AAC) is:
"If my child starts using an AAC device, will they stop trying to talk?"
It's an understandable fear.
Every parent wants to hear their child's voice. Many worry that introducing a communication device means they're giving up on speech.
The good news is that decades of research continue to show the opposite.
AAC does not prevent children from learning to talk. In fact, many children who use AAC develop spoken language just as quickly, or even more quickly, because they are finally able to communicate successfully while speech continues to develop.
Now, exciting new research published in 2026 adds another reason for families to feel hopeful. It found that preschoolers using AAC can learn much more than requesting their favorite toy or snack. With the right therapy, they can begin building sentences and expressing more complex thoughts.
Augmentative and Alternative Communication (AAC) includes any tool that helps a child communicate when spoken language is difficult.
AAC may include:
Children may benefit from AAC for many different reasons, including:
The goal of AAC is simple:
Give children a reliable way to communicate while continuing to support spoken language whenever possible.
Researchers recently studied preschool-aged children who used AAC to answer an important question:
Can children learn to build complete sentences using AAC, instead of communicating with only single words or simple requests?
The answer was yes.
Children who participated in a specialized AAC language program learned to:
Children who only received basic AAC education showed much smaller improvements.
This is exciting because it shows that AAC is much more than a way to ask for a snack or favorite toy. It can help children express ideas, tell stories, answer questions, and participate in meaningful conversations.
Imagine knowing exactly what you want to say but not being able to say it.
That is the reality many children face every day.
When children cannot communicate, they often become frustrated because others don't understand what they need, want, or feel.
AAC gives children a way to share their thoughts while speech continues to develop.
For many families, having a reliable way to communicate can reduce frustration, increase confidence, and create more opportunities for meaningful interaction at home, school, and in the community.
Many children first learn to use AAC by requesting things they want.
For example:
"I want juice."
"I want bubbles."
While those are important first steps, communication doesn't stop there.
Children also want to:
The new research shows that children can learn these more advanced communication skills when therapy focuses on building sentences and grammar, not just vocabulary.
No.
AAC is not a replacement for speech therapy.
Instead, it works alongside speech therapy.
For children with conditions such as childhood apraxia of speech, speech-language pathologists continue to work on improving speech production while AAC provides another way to communicate during that journey.
Children are encouraged to use spoken words whenever they can, while AAC gives them another way to successfully express themselves when speech is difficult.
The goal is always communication, using every tool available.
Not necessarily.
Every child's communication journey is different.
Some children use AAC throughout their lives.
Others gradually rely less on their device as their spoken language develops.
The purpose of AAC is never to replace speech.
Its purpose is to ensure that children have a voice today while continuing to build all of their communication skills for tomorrow.
It may be time to speak with a speech-language pathologist if your child:
An evaluation helps determine whether AAC could support your child's communication while continuing to encourage spoken language development.
Choosing an AAC device is only the beginning.
Learning how to use it effectively is what helps children truly communicate.
At Progressive Pediatric Therapy, our speech-language pathologists create individualized therapy plans that help children move beyond simply pressing buttons.
Depending on your child's needs, therapy may focus on helping them:
We also believe families are an essential part of the process.
Parents, siblings, grandparents, teachers, and caregivers all play an important role in helping children use AAC throughout everyday life. Our therapists work closely with families so communication continues long after each therapy session ends.
This new research offers encouraging news for families considering AAC.
Not only does AAC support communication without preventing speech development, but children can also learn to build longer, more meaningful messages when therapy focuses on grammar and sentence building, not just requesting.
Every child deserves a way to share their thoughts, ideas, feelings, and personality with the people around them.
If your child struggles to communicate, don't wait to seek answers.
An AAC evaluation can help determine whether additional communication supports could help your child express themselves with greater confidence while continuing to build spoken language.
At Progressive Pediatric Therapy, we're passionate about helping every child find their voice, whatever form that voice may take.
