When a child is diagnosed with autism, the service recommendations that follow can feel like a lot to sort through. ABA therapy. Speech therapy. Sometimes both, sometimes one, sometimes with a long waitlist standing between the recommendation and actually getting started. Families are left piecing together what each service actually does, whether they overlap, and how to make decisions when time and bandwidth are limited.
Here’s what’s worth knowing: ABA and speech therapy are not doing the same job. But they’re also not working against each other. They cover different territory, and for many kids on the spectrum, they’re most effective when they run alongside each other.
How To Help Improve Speech for Your Child With Autism
Speech-language pathology (SLP) is built around communication — how a child receives, processes, and expresses language. For children on the autism spectrum, a speech therapist might work on:
- Developing verbal language in kids who are nonverbal or minimally verbal.
- Building vocabulary and sentence structure.
- Improving back-and-forth conversation skills.
- Addressing articulation — how clearly a child pronounces words.
- Teaching alternative communication methods, like AAC devices or picture exchange systems.
- Working on pragmatic language — the social side of talking, like staying on topic, reading tone, or understanding implied meaning.
Speech therapy is typically delivered in focused sessions — usually 30 to 60 minutes — with a licensed speech-language pathologist. Sessions tend to be targeted and skill-specific. A session might zero in on one communication goal, work it from several angles, and send the child home with practice strategies to try in between.
For many kids on the spectrum, speech therapy starts early and stays relevant for years. A preschooler building first words and a teenager working on conversational fluency are both well within scope.
How ABA Therapy Increases Communication Alongside Speech Therapy
Applied behavior analysis is a broader framework. It uses evidence-based principles — reinforcement, prompting, shaping, data collection — to build skills and reduce behaviors that are causing distress or interfering with daily life.
ABA can target communication, but that’s one piece of a much wider picture. It also addresses:
- Daily living skills like hygiene, dressing, and managing routines.
- Social skills — reading situations, understanding expectations, building relationships.
- Behaviors that are self-injurious, dangerous, or significantly disruptive.
- Academic readiness and foundational learning skills.
- Emotional regulation and flexibility.
- Independence skills for older adolescents preparing for adulthood.
ABA therapy is typically more intensive in terms of hours. A BCBA designs and oversees the program, and an RBT carries out much of the direct session work. Depending on a child’s needs, services might range from targeted weekly support to 20 or more hours per week for more intensive programming.
Where the Two Approaches Connect
Both disciplines care about communication — and both draw from overlapping principles in places.
ABA programs often include functional communication training (FCT), a structured approach to teaching children to express their needs in more effective ways. A child who hits when overwhelmed might learn to hand over a card, press a button, or use a phrase instead. That’s behavior analysis working directly on communication, often in close coordination with what a speech therapist is building.
Speech therapists, meanwhile, frequently use reinforcement strategies that parallel ABA techniques. Many SLPs working with autistic children stay in close contact with ABA teams to make sure goals aren’t pulling in different directions.
The overlap is a feature. What one discipline goes deep on, the other tends to reinforce in a different context. When providers communicate, children get a more consistent experience across settings — and skills learned in one place are more likely to carry over to others.
Many Families Typically End Up Using Both
There’s no single formula, but some patterns show up consistently.
Speech therapy tends to be the starting point when the primary concern is language — a child who isn’t yet talking, or who talks but struggles significantly with conversation or social communication. It’s also the natural lead when a child is working with an AAC system and needs help building or refining it.
ABA therapy tends to come in when behavioral challenges are affecting safety, learning, or daily life — or when a child needs support across multiple skill areas at once. It’s also frequently recommended following a functional behavior assessment, when specific patterns have been identified that call for a structured, consistent response.
Both together make the most sense when communication delays and behavioral challenges are present at the same time, when early intervention is underway, or when progress in one area has stalled because of difficulties in the other. For many families, especially those with younger children, the recommendation from the start is to pursue both with providers who coordinate their approaches.
Questions Worth Asking About ABA Therapy in Colorado
If you’re sorting out what makes sense for your child, these can help move the conversation forward.
For a speech therapist: What specific goals would you target for my child? How do you coordinate with an ABA team if one is involved?
For an ABA provider: What does your assessment process look like before you build a program? How do you approach communication goals — do you work alongside an SLP?
For any provider: How will we know if this is working? What’s the plan for reducing support as skills develop? What happens if we’re not seeing progress after a few months?
Good providers welcome these questions. Clear, direct answers are a reasonable expectation — and the quality of those answers tells you something about how a provider actually works.

ABA and speech therapy aren’t interchangeable, and they’re not trying to be. Speech therapy goes deep on communication and language. ABA covers a wider range of skill areas and uses behavioral principles to drive progress across multiple areas of daily life. For a lot of children on the spectrum, both have a meaningful role — sometimes at different stages, sometimes running side by side.
What matters most is getting an honest picture of what your child actually needs, rather than defaulting to whatever’s most available or most commonly recommended without context.
