Empowering Nonverbal Children Through Alternative Communication in Cambodia

In Cambodia, many families are learning that speech isn’t the only way a child can communicate. For some children—particularly those who are nonverbal or minimally verbal—using words can be extremely difficult. These children may struggle to say even basic needs like “I’m hungry” or “Help me.” But with the right tools and support, they can communicate.

In Phnom Penh, OrbRom Center is helping nonverbal children find their voices through Alternative and Augmentative Communication (AAC). Whether through pictures, signs, or speech-generating devices, AAC empowers children to express themselves, connect with others, and reduce the frustration that often comes with being misunderstood.

Understanding Nonverbal Communication

Nonverbal children may be completely silent, use very few spoken words, or rely on gestures and sounds. This is often the case in children with:

• Autism spectrum disorder

• Childhood apraxia of speech

• Global developmental delay

• Neurological conditions (e.g., cerebral palsy)

• Selective mutism

In Cambodia, especially in rural areas, these children are often overlooked or assumed to be “just quiet.” But in Phnom Penh, greater awareness is leading more families to seek alternatives that support real communication.

What Is AAC?

AAC (Alternative and Augmentative Communication) refers to any tool or strategy used to support or replace spoken language. It includes:

• PECS (Picture Exchange Communication System)

• Sign language or gesture-based systems

• Communication boards with pictures or symbols

• Speech-generating devices or tablet apps

AAC is not a last resort—it’s a communication bridge. Research shows that children who use AAC often develop more spoken language over time because they experience less frustration and more interaction.

How AAC Is Used at OrbRom Center in Phnom Penh

At OrbRom Center, therapists work with each child to determine the most suitable AAC method. The process involves:

• Assessing the child’s current communication abilities

• Selecting the right AAC tools based on strengths and needs

• Teaching the child how to use them in daily routines

• Training parents and caregivers to use AAC consistently at home

• Gradually expanding vocabulary and sentence-building over time

For example, a nonverbal child might start by handing a picture of “juice” to request a drink. Later, they may use a communication app to say, “I want juice, please.” Every step builds confidence and language foundation.

Benefits of AAC for Cambodian Children

When AAC is introduced early and used consistently, nonverbal children experience:

• Reduced frustration and behavioral outbursts

• Increased engagement with family, peers, and teachers

• Improved social-emotional development

• Greater independence and ability to express preferences

In Phnom Penh, where bilingual environments are common, AAC can support both Khmer and English language learning—helping children thrive in school and community settings.

Common Myths About Nonverbal Children and AAC

“If we use pictures, my child will never learn to talk.”
This is false. AAC actually supports speech development by giving children a way to practice communication. Many children begin to speak more once they feel successful using AAC.

“My child is too young for AAC.”
AAC can be introduced as early as 18 months. The earlier children learn to communicate, the better their long-term outcomes.

“I don’t know how to use AAC at home.”
That’s why OrbRom trains parents, teachers, and even siblings—so AAC becomes part of everyday life.

What Phnom Penh Parents Can Do

Cambodian families can begin supporting their nonverbal child today:

• Use simple visuals at home (photos of food, toys, people)

• Model gestures and signs when speaking

• Create routines with choices (e.g., “Do you want banana or bread?” with pictures)

• Encourage all forms of communication—pointing, eye contact, or touching a symbol

• Stay patient and positive—progress may be slow but is always meaningful

Final Thoughts: Every Child Has Something to Say

Speech is one way to communicate—but not the only way. Nonverbal children in Cambodia deserve tools that allow them to share their thoughts, feelings, and ideas with the world.

At OrbRom Center in Phnom Penh, AAC therapy is opening doors for children who previously had no way to express themselves. With the right support, even a child who has never spoken a word can tell their story—clearly, confidently, and in their own way.
