- The myth that AAC delays speech blocks communication access for many children.
- Research reviews find AAC does not impede speech and may modestly increase it.
- Communication is the goal, and AAC reduces frustration from unmet needs.
- Every autistic person who needs AAC has a right to it now, not later.
This myth can delay communication access for autistic children. Some parents are told by well-meaning educators and clinicians to hold off on AAC, to wait and see if speech develops first.
The research does not support this position. A 2006 research review found that none of the 27 cases with the strongest evidence showed decreases in speech after AAC intervention, and 89 percent showed gains in speech, mostly modest ones. A 2008 systematic review focused on autistic children concluded that AAC interventions do not impede speech production and may increase it, while noting the gains were modest.
The logic of the myth is backwards. Communication is the goal. Speech is one form of communication. If a child does not yet have reliable access to spoken communication, giving them a communication tool increases their ability to communicate, and, importantly, reduces the frustration and behavioral consequences of being unable to express needs, wants, and thoughts.
A child with a reliable way to communicate has a way to be understood now, whether or not speech comes later, and some children add or increase spoken language alongside their AAC use.
Every autistic person who needs AAC has a right to it. This includes young children, minimally verbal children, and nonspeaking adults. The question is not "are they ready for AAC" it is "which AAC system fits their needs and access right now."
If your child's school or therapist is recommending waiting on AAC, ask them to provide peer-reviewed evidence for that recommendation, and share the reviews above. You can find more on AAC from ASHA and the AAC-RERC (Rehabilitation Engineering Research Center on AAC).

Frequently Asked Questions
Will using AAC stop my child from developing spoken language?
No. A 2006 research review found no decreases in speech after AAC intervention among the cases with the strongest evidence, and 89 percent showed gains, mostly modest. A 2008 systematic review of autistic children concluded that AAC does not impede speech production and may increase it. The advice to wait and see if speech develops first is not supported by that evidence.
Why is the advice to wait on AAC backwards?
Communication is the goal, and speech is only one form of communication. If a child does not yet have reliable access to spoken language, giving them a communication tool increases their ability to communicate and reduces the frustration and behavioral consequences of being unable to express needs, wants, and thoughts. A reliable way to communicate lets a child be understood now, whether or not speech comes later.
What should I do if a therapist recommends waiting on AAC?
Ask them to provide peer-reviewed evidence for that recommendation, and share the research reviews finding that AAC does not impede speech. More information on AAC is available through ASHA and the AAC-RERC. Every autistic person who needs AAC has a right to it, including young children, minimally verbal children, and nonspeaking adults.
