Speech therapy, communication and AAC

In short. A speech therapist's work with a child with ASD is much broader than setting sounds. The main goal is not "to force out words" but to expand communication in any available format.

This text is about how speech therapy help actually works, and about AAC, a topic surrounded by many myths.

What a speech therapist really does

A speech therapist is a specialist in speech, language, and communication. NICE recommends including them in the team when working with speech difficulties. ASHA describes the speech therapist as one of the central specialists for children with ASD.

Areas of work.

• Understanding spoken language. Whether the child understands what is said to them.
• Joint attention. The ability to look at something together and share attention.
• Gestures. Especially pointing.
• Requests, refusals, commenting. Basic communicative functions.
• Play. Social play skills.
• Phrases, dialogue. If speech is available.
• AAC. Augmentative and alternative communication, if speech is difficult.
• Oral-motor difficulties and child feeding. If the speech therapist has appropriate training.

Why communication is broader than speech

This is the key point. Speech is one of the ways of communication. Not the only one.

Communication can be.

• Gestures. A simple gesture "come," wave, clap, point with a finger.
• Gaze. Where they look, whether they direct their gaze.
• Pictures. Simple images of objects and actions.
• Communication boards. Cards on one tablet.
• PECS. Cards that the child hands over to ask.
• AAC devices. Electronic tools with speech synthesis.
• Sign language. Ukrainian or another.
• Vocalizations. Sounds that have meaning for the child.
• Behavior. Yes. Behavior is also a signal.

For many children, the first big step is not "to start speaking" but to get a reliable way to say "no," "help," "more," "it hurts," "stop," "break," "done."

This often reduces frustration and difficult behavior. The child has something to ask with, instead of screaming or hitting.

Does AAC "take away" speech

The most common parental fear. "If I give cards or a tablet, the child will not start to speak."

This fear is not supported by data.

Systematic reviews show. AAC does not slow down the development of spoken language. In many cases on the contrary, it supports it. ASHA writes directly that AAC does not interfere with speech development.

The logic is this. When a child has a way to express what they want, frustration decreases. This creates space for speech to develop, not blocks it. If speech for some reasons does not come, AAC remains a reliable life tool.

This applies to both simple PECS cards and tablets with speech synthesis.

Evidence-based speech therapy approaches

The best research support goes to approaches that build communication in natural everyday interaction.

• Social-communicative interventions. With play strategies. NICE recommends exactly this format.
• Parent-mediated interventions. When the speech therapist teaches parents strategies that they apply at home. A Cochrane review shows benefits for adult-child interaction.
• PACT (Preschool Autism Communication Trial). Long-term follow-up showed lasting positive changes in some symptoms and social communication.
• Joint attention interventions. Work on the child sharing attention to an object or event with another person. A meta-analysis shows a positive effect.
• Naturalistic developmental behavioral interventions with AAC. A promising approach for children with minimal speech.

These are not "method brands." These are approaches with a transparent evidence base.

PECS, what is important to know

PECS (Picture Exchange Communication System) is one of the popular formats of simple AAC. Cards that the child hands over to request.

Meta-analyses show. PECS improves functional communication, especially in requests and initiations. But the increase in spoken speech itself is less consistent.

This means. PECS can be very useful for some children. But it is not worth selling as a guarantee that "the child will definitely start to speak." It is a communication tool that works as intended.

It is also important to monitor generalization. Whether the child uses PECS not only in the speech therapist's office but also at home, in kindergarten, with different people.

Hanen approaches

Hanen, especially the "More Than Words" program, has some evidence base as structured parent coaching programs.

Honestly. This base is better described as promising but not universal. It is not "definitely the better path for every child." It is one of the options that may suit families who find it convenient to teach the adult strategies of everyday communication.

Questions for the speech therapist

• Do you evaluate not only sounds but also language comprehension, joint attention, functional communication?
• Do you work with AAC and how do you decide when it is needed?
• How do you involve parents and what will we do at home?
• What daily goals do we set, requests, refusals, taking turns, play, understanding instructions?
• How do you measure progress?
• What do you do if the child is silent, protests, or speaks in "echolalia"?
• Do you cooperate with the occupational therapist, educators, teachers, behavioral specialist?
• If there are difficulties with eating, do you have training to work with feeding?

Red flags in speech therapy

• A promise to "launch speech in 10 sessions."
• Working only on sounds, ignoring communication.
• A ban on AAC because of the myth "then they will not start to speak."
• Mechanical repetition without understanding and without motivation.
• Absence of home strategies.
• Does not assess understanding of spoken language.
• Shame, pressure, punishment for mistakes.
• Ignoring the sensory needs of the child.
