One of the most common concerns parents and caregivers have when considering an augmentative and alternative communication (AAC) device is whether it will prevent their child from developing natural speech. It is a reasonable worry: if a child has a device that speaks for them, why would they bother learning to talk on their own?
Fortunately, decades of research provide a clear and reassuring answer: AAC does not inhibit speech development. In fact, the evidence overwhelmingly suggests the opposite.
What the Research Shows
A landmark meta-analysis by Millar, Light, and Schlosser (2006) examined 23 studies involving individuals with developmental disabilities who used AAC. The findings were striking: in no case did AAC use result in a decrease in natural speech production. Instead, the vast majority of participants showed gains in speech output after AAC was introduced.
More recent studies have reinforced these conclusions. Romski and Sevcik's longitudinal research demonstrated that children who used speech-generating devices alongside traditional therapy showed significantly greater improvements in spoken language than children who received speech therapy alone. The device did not replace speech; it served as a bridge to it.
Why AAC Supports Speech
There are several reasons AAC devices can actually promote natural speech development. First, they reduce the frustration and communication breakdowns that can make children reluctant to communicate at all. When a child successfully conveys a message using a device, they experience the power of communication, which increases their motivation to interact.
Second, many AAC devices — including the Talk To Me 100 — pair auditory output with visual symbols. This multi-sensory approach reinforces the connection between words, meanings, and motor planning. The child hears the word, sees the symbol, and presses a button, creating multiple neural pathways for language learning.
Third, AAC provides a consistent model. Children hear correct productions of words every time they press a button. This reliable auditory input supports phonological development and gives children a target to imitate when they are ready.
Professional Consensus
The American Speech-Language-Hearing Association (ASHA) firmly supports early introduction of AAC, stating that there is no prerequisite skill set a child must demonstrate before benefiting from AAC. ASHA's position is that AAC should be introduced as early as possible and used alongside other speech-language interventions, not as a last resort.
The National Joint Committee for the Communication Needs of Persons with Severe Disabilities echoes this stance, affirming that all individuals have the right to communication access and that AAC is a vital part of comprehensive communication support.
The Bottom Line
Waiting to introduce AAC in hopes that speech will develop on its own can actually delay a child's overall communication growth. Every moment without a means to communicate is a missed opportunity for language learning, social connection, and cognitive development. AAC devices like the Talk To Me 100 give children a voice today while building the foundation for speech tomorrow.
If you are considering AAC for your child, know that the research is on your side. You are not choosing between a device and speech — you are giving your child the best possible chance at both.
