The Connection Between Sensory Processing and Speech Development in Children – Insights from Phnom Penh

In Phnom Penh, an increasing number of parents are seeking answers to their children’s communication delays. Often, the focus is solely on speech—words, sounds, and sentence structure. But what many don’t realize is that speech development is deeply connected to how a child processes sensory input.

At OrbRom Center, we take a holistic approach to speech therapy, recognizing that for many children, especially those with autism, ADHD, or developmental delays, sensory regulation is the foundation for effective communication. This blog explores the vital link between sensory processing and speech development—and how combining speech therapy with sensory support can help children thrive.

What Is Sensory Processing?

Sensory processing refers to the way the nervous system receives and responds to information from the senses—sight, sound, touch, taste, smell, balance, and body awareness. For most children, this happens naturally. But for some, the brain has trouble organizing and responding appropriately to sensory input.

Signs of sensory processing issues include:

• Sensitivity to noise, lights, or textures

• Trouble sitting still or focusing

• Avoiding messy play or certain movements

• Becoming overwhelmed in group settings

• Seeking constant movement or deep pressure

These challenges can interfere with speech development, especially if the child is overwhelmed, dysregulated, or distracted by their environment.

How Sensory Challenges Affect Communication

When a child’s sensory system is dysregulated, communication becomes difficult. Imagine trying to focus on speaking while your clothes feel itchy, the lights are too bright, and background noise feels unbearable. This is the daily experience for many children with sensory processing differences.

Children who are over- or under-sensitive to sensory input may:

• Avoid eye contact or social interaction

• Struggle to attend to instructions or respond to questions

• Have meltdowns during speech tasks

• Use behavior (e.g., running, shouting) instead of words to communicate

These behaviors are not “bad” or “defiant”—they are signs that the child’s sensory system needs support.

The OrbRom Center Approach: Integrating Speech and Sensory Support

At OrbRom Center in Phnom Penh, we recognize that speech therapy alone may not be enough for children with sensory needs. That’s why we use an integrated approach, where speech therapy is combined with sensory-informed strategies.

Our therapists create calm, engaging, and regulated environments so that each child feels safe and ready to communicate. Some of the strategies we use include:

• Sensory warm-ups before speech tasks (e.g., jumping, rocking, deep pressure)

• Visual schedules to reduce unpredictability and support understanding

• Noise control tools to reduce distractions

• Flexible seating and movement breaks during sessions

• Co-treatment with our occupational therapists when needed

This integrated model is especially helpful for children with autism spectrum disorder, ADHD, or anxiety who often present with co-occurring sensory and speech needs.

Tools That Help Regulate Sensory Input at Home

In addition to in-center support, parents can create sensory-friendly environments at home. OrbRom Center’s Sensory Shop includes tools that help children feel calmer and more focused—ideal for supporting speech development during everyday routines.

Recommended products include:

• Sensory Rocking Chair: Helps children calm their bodies before or during communication activities.

• Sensory Peapod: Offers deep pressure input to regulate emotions and prepare for learning.

• Noise Cancelling Headphones: Perfect for children sensitive to sound, especially in busy environments.

• Sleep Sound Machine: Promotes deeper sleep, which is vital for language development and emotional regulation.

These tools are carefully selected by our therapists and are often used as part of home practice programs.

When to Seek Help

If your child shows signs of both sensory issues and communication delays, don’t wait. The combination may indicate a need for both speech and occupational therapy. Early intervention offers the best chance for long-term progress and helps children build the tools they need to participate in school, form friendships, and express their thoughts clearly.

At OrbRom Center in Phnom Penh, our multidisciplinary team works together to evaluate and support children from a whole-child perspective. If needed, we begin with a Developmental Assessment to identify which services are most appropriate.

Building Strong Communication Starts with Regulation

Speech therapy is more than just repeating words—it’s about helping children communicate effectively in real-world situations. For many, this journey begins with sensory regulation. When the body and brain are calm, communication becomes possible, and meaningful progress follows.
