A question we often hear from families is: “If my child starts using AAC, will they stop trying to talk?”
The truth is: AAC does not stop speech development. In fact, it often supports and encourages speech, giving children more ways to communicate while their spoken language is still developing.
Why AAC Matters When Speech Isn’t Clear
When a child isn’t yet speaking or doesn’t have a clear way to communicate:
- They may babble, gesture, or make sounds that mean something to them, but adults may not understand.
- Missed communication moments can slow language learning because language develops through interaction: a child attempts, someone responds, and the back-and-forth helps them learn.
- Frustration can build for both the child and the family when messages are missed.
AAC helps by:
- Providing a clearer way for the child to express themselves.
- Ensuring their attempts are understood and responded to.
- Increasing opportunities for interaction, which supports language development.
How AAC Supports Speech
AAC isn’t a replacement for speech, it works alongside it:
- Adults model spoken words while signing or using AAC symbols.
- Example: saying “more bubbles” while signing more or pressing more on a device.
- This helps children hear words more clearly and often
- Slows down speech slightly, making it easier to process.
- Helps children join in communication while learning to talk.
Key takeaway: AAC provides more opportunities to hear and practise language, rather than reducing speech.
Tools That Work Together
Many children use more than one way to communicate at the same time. As speech develops, Key Word Sign can shift to prompting words a child is learning to say, and some families keep using it alongside speech.
Communication tools often work together, rather than competing with each other.
Conclusion
The idea that AAC prevents children from talking is a common myth. In reality, AAC helps children communicate successfully, increases opportunities for interaction, and supports speech development through repeated modelling of words. By giving children multiple ways to express themselves, through speech, signs, or devices, we help them build confidence, make connections, and grow their language skills.
At My Therapy Space, our team works alongside families to find the communication tools that best support each child, helping every child to have a voice that can be heard and understood.
