ABA Therapy vs Speech Therapy: What’s the Real Difference?

After an autism diagnosis, parents hear a lot of new terms fast. ABA therapy. Speech therapy. BCBA. SLP. It can feel like learning a second language while you are still processing the first piece of news.

One question comes up constantly in those early weeks: do I need ABA therapy, speech therapy, or both? The honest answer is that these two therapies are not competing options. They work on different parts of your child’s development, and for many families, the real question is not which one to pick, but how to use both well.

This guide breaks down what each therapy actually does, where they overlap, and how to figure out what your child needs right now.

What Is ABA Therapy?

Applied Behavior Analysis, known as ABA, is a therapy built around understanding why a behavior happens and teaching new, more useful behaviors in its place. It is one of the most studied approaches for children with different levels of autism. Centers for Disease Control and Prevention lists it among the recognized treatment options for autism spectrum disorder.

Who Delivers ABA Therapy

A Board Certified Behavior Analyst (BCBA) designs the treatment plan based on a child’s specific goals. The Behavior Analyst Certification Board oversees this credential and sets the standards BCBAs must meet. A Registered Behavior Technician (RBT) usually delivers the day-to-day sessions under the BCBA’s supervision.

What ABA Therapy Targets

ABA therapy covers a wide range of skills, not just communication. A typical ABA plan might include:

• Following instructions, like responding to simple directions such as “come here” or “sit down”
• Reducing challenging behavior, including meltdowns, aggression, or self-injury, by identifying triggers and teaching calmer alternatives
• Daily living skills, such as brushing teeth, getting dressed, or using utensils at meals
• Social skills, like taking turns, tolerating eye contact, or playing alongside another child
• Communication, through a structured framework that teaches a child to request items, label objects, or answer questions using prompts and reinforcement

ABA sessions are typically intensive. Many children receive 10 to 40 hours of therapy per week, often at home, in a clinic, or sometimes at school.

What Is Speech Therapy?

Speech therapy is delivered by a speech-language pathologist, or SLP. Unlike ABA, which covers behavior broadly, speech therapy focuses on one clear area: communication. The American Speech-Language-Hearing Association sets training and practice standards for SLPs working with autistic children.

Who Delivers Speech Therapy

SLPs hold a graduate degree and a clinical license specific to speech-language pathology. They assess how a child understands language, produces sounds and words, and uses language socially.

What Speech Therapy Targets

A speech therapy plan might include:

• Articulation, helping a child pronounce sounds clearly so words are easier for others to understand
• Expressive language, building vocabulary and grammar so a child can form longer, more complete sentences
• Receptive language, improving how well a child understands what is said to them, not just what they can say back
• Social communication, teaching a child how to hold a back-and-forth conversation or read facial expressions
• Alternative communication, introducing tools like picture exchange systems or speech-generating devices for children who are nonverbal or minimally verbal

Speech therapy sessions tend to be shorter and less frequent than ABA, often one to three sessions a week, and they are usually more play-based and child-led.

ABA Therapy vs Speech Therapy: Side-by-Side Comparison

Where the Two Therapies Overlap

Here is the simplest way to think about it. Speech therapy asks, “How does this child communicate, and how can we build that skill?” ABA asks, “What is driving this child’s behavior, and how can we teach a better response?”

Communication is actually one of the behaviors ABA can target. But ABA sees communication through a behavioral lens, built on reinforcement and repeated practice, while speech therapy sees it through a developmental and linguistic lens, built on natural back-and-forth interaction.

Think of it this way. If your child struggles to say “I want juice,” a speech therapist works on the sounds, words, and sentence structure needed to say it clearly. An ABA therapist works on teaching the child to use that phrase consistently to get what they want, instead of grabbing the cup or crying, and on building the patience to wait a few seconds after they ask. Both skills matter. Neither one replaces the other.

How to Tell Which Therapy Your Child Needs

This is the part parents care about most, and it depends on what your child’s biggest challenges look like right now.

Signs Speech Therapy May Be the Priority

• Your child has clear communication skills but struggles specifically with pronunciation
• Forming full sentences is harder than it should be for their age
• Family can understand them, but others outside the home often cannot
• Behavior is not a major day-to-day concern

Signs ABA May Be the Priority

• Your child struggles to follow directions, even simple ones
• Meltdowns or aggression happen often, especially during transitions
• Daily routines like getting dressed or brushing teeth are a daily battle
• Social behavior, like playing near other children, needs active support

Signs Your Child May Benefit From Both

• A speech delay shows up alongside frequent frustration-driven behavior
• Your child acts out specifically because they cannot express what they need
• Progress in one area seems to stall without support in the other

This overlap shows up constantly in our work with families at Happy Hearts ABA. A child who cannot yet ask for a break will often act out instead, not because they are being difficult, but because they don’t have the words yet. ABA can reduce that frustration-driven behavior in the moment, while speech therapy builds the actual words the child needs so the frustration happens less in the first place.

What a Combined Therapy Week Can Look Like

It helps to see this in practice instead of just in theory. Here is a realistic example for a 5-year-old working on both communication and behavior goals:

• Monday, Wednesday, Friday afternoons: ABA sessions at home, two hours each, focused on following two-step instructions, reducing tantrum behavior around transitions, and practicing requesting with a few core words
• Tuesday and Thursday mornings: Speech therapy sessions, 30 to 45 minutes each, at a clinic, focused on expanding sentence length and working on specific sounds
• Ongoing: The BCBA and SLP exchange brief monthly updates, so the words the SLP introduces in speech sessions get reinforced consistently during the ABA hours throughout the rest of the week

Not every family’s schedule looks exactly like this. Some children need far more ABA hours and lighter speech support. Others need the opposite. The point is not to copy this exact split, but to understand that the two therapies are meant to run side by side, not compete for the same slot on the calendar.

Why Pairing ABA and Speech Therapy Often Works Best

It is not unusual for a child’s team to include a BCBA, an RBT, and an SLP, all working from the same overall goals. Most private insurance plans and Medicaid cover ABA and speech therapy as separate benefits, so accessing both usually doesn’t mean choosing one over the other financially. The National Institute on Deafness and Other Communication Disorders notes that a coordinated team approach tends to produce better communication outcomes for autistic children than any single therapy alone.

When both providers coordinate, the results tend to be stronger than either therapy running on its own. For example, an SLP might introduce a new word for “stop,” and the ABA team reinforces that same word consistently across every session, so the skill actually sticks in daily life, not just inside one therapy room.

Questions to Ask When Choosing a Provider

• Does the BCBA communicate with other therapists on my child’s team?
• How is progress measured and shared with me?
• What does a typical session actually look like?
• Is the therapy based on my child’s current, individual needs, not a generic template?
• How are sessions adjusted as my child grows and reaches goals?

The Bottom Line for Parents

ABA therapy and speech therapy are not rivals fighting for your child’s schedule. They are two different tools built for two different jobs. Speech therapy builds the words. ABA builds the behavior, routines, and social skills that surround those words. Many autistic children benefit most when both are part of the plan and work in the same direction at the same time.

If you are trying to figure out what mix of support is right for your child, a conversation with a BCBA is a good place to start. At Happy Hearts ABA, our team builds individualized care plans and works alongside your child’s speech therapist and other providers, so everyone in their support system is pulling in the same direction.

Frequently Asked Questions

Is ABA therapy the same as speech therapy?

No. ABA focuses more broadly on behavior, including communication, while speech therapy focuses specifically on speech sounds and language.

How many hours a week does ABA therapy usually require?

Most children receive between 10 and 40 hours a week, depending on their individual treatment plan and needs.

Can a speech delay cause behavior problems in autistic children?

Yes. Many children act out from frustration when they cannot express their needs, which often improves with combined support.

Does insurance cover both ABA and speech therapy?

Most private insurance plans and Medicaid cover both as separate benefits, so families can usually access each without trade-offs.

How do I know if my child’s current therapy plan is working?

Look for regular, measurable progress updates from your provider, not just general impressions after each session.
