How Speech and Occupational Therapy Support Children with Autism

Written by: Daniel Woon, Principal Speech Therapist 

When a child receives a diagnosis of Autism Spectrum Disorder (ASD), parents are often presented with a list of recommended services. Two of the most common are Speech and Language Therapy (SLT) and Occupational Therapy (OT). 

While they may seem like separate disciplines, they are actually two sides of the same coin. In Singapore’s clinical landscape, an integrated approach where SLT and OT work in tandem is considered the gold standard for helping children with autism reach their full potential.  

What is the Difference Between Speech Therapy and Occupational Therapy?  

• Speech Therapy focuses on communication. This includes spoken language, understanding others, social cues, and using alternative tools like Augmented and Alternative Communication (AAC). 

  
  

• Occupational Therapy focuses on function and regulation. This includes sensory processing, fine motor skills (like writing or using a spoon), and emotional regulation. 

3 Ways that Speech Therapy and Occupational Therapy Work Together 

1. Regulation Before Communication 

A child cannot learn to speak if their body feels out of sync. If a child is overstimulated by the lights in a room or the sound of a fan, their brain is in survival mode, not learning mode. 

• The Occupational Therapist’s Role: Helps the child regulate their sensory system so they are calm and alert. 

• The Speech Therapist’s Role: As the child learns how to manage emotional and sensory regulation, the Speech Therapist can then introduce language tasks effectively. 

• The Result: Therapy is more productive because the child is physically and emotionally ready to engage. 

2. Social Participation and Play 

For children with Autism, play is the "work" of childhood. However, play requires both motor planning (OT) and social understanding (SLT). 

• The Occupational Therapist’s Role: Teaches the child how to physically manipulate toys and navigate the space around them. 

• The Speech Therapist’s Role: Teaches the child how to use those toys to interact with others, such as taking turns, making requests, and sharing enjoyment. 

3. Independence in Daily Life 

Whether it’s sitting at the dinner table or attending a birthday party, daily activities require a mix of skills. 

• Example: At mealtime, an occupational therapist works on the sensory tolerance of different food textures and the motor skills to use a fork. A speech therapist works on the child’s ability to request "more," "finished," or "help" during the meal. 

Why Choose an Integrated Early Intervention Centre? 

When you choose an early intervention centre that offers both Speech and Language Therapy and Occupational Therapy, you benefit from: 

1. Holistic Progress: We don’t just look at “speech" or "movement" in isolation, we look at the whole child. 

2. Shared Goals: Your child’s therapists talk to each other. If the OT finds a specific "calming" technique that works, they share it with the SLT to use during language sessions. 

3. Reduced Parent Burnout: Managing one schedule at one location is significantly easier for busy Singaporean families.
