Low-Tech vs. High-Tech AAC: Which Communication Solution is Right for Your Child?
Augmentative and Alternative Communication (AAC) gives individuals with speech or language challenges the tools they need to express themselves, connect with others, and participate in daily life. Today’s AAC options range from simple low-tech boards to advanced high-tech devices — each with its own advantages.
In this guide, we’ll break down low-tech AAC and high-tech AAC, explore the pros and cons of each, and share tips on how to choose the right solution with the help of a Speech-Language Pathologist (SLP) or Occupational Therapist (OT).
What Is Low-Tech AAC?
Low-tech AAC solutions are simple, affordable, and non-electronic tools that support communication without requiring batteries or internet access. These options are often a starting point for children or adults who need functional communication tools right away.
Examples of Low-Tech AAC:
Communication Boards: Picture or word boards customized for the user’s needs.
Picture Exchange Communication System (PECS): Uses picture cards that the user exchanges to communicate wants and needs.
Sign Language: A visual-gestural system ideal for Deaf individuals or those who benefit from a hands-on communication method.
Communication Books: Portable books with pages of symbols or pictures for quick reference.
Advantages of Low-Tech AAC:
Easy to use and quick to learn
Affordable and widely accessible
Reliable — no batteries, charging, or tech support needed
What Is High-Tech AAC?
High-tech AAC options use electronic devices and digital software to create more advanced, customizable communication systems. These are ideal for users who need a broader vocabulary, voice output, or alternative access methods.
Examples of High-Tech AAC:
Speech-Generating Devices (SGDs): Customizable devices that produce spoken output using text or symbols. Can be controlled via touch, switches, or eye gaze.
AAC Apps: Tablet or smartphone apps with personalized vocabulary, voices, and symbol sets.
Eye-Gaze Technology: Allows users to operate a device by tracking their eye movements — often used by individuals with severe physical limitations.
Advantages of High-Tech AAC:
Wide vocabulary range and personalization options
Supports advanced grammar and sentence building
Portable and lightweight for on-the-go communication
Can be updated as needs evolve
How to Choose the Right AAC Solution
Selecting between low-tech and high-tech AAC isn’t a one-size-fits-all decision. The process should involve:
A Comprehensive Evaluation by an SLP: They will assess communication skills, cognitive abilities, and language goals to recommend the best system.
An Occupational Therapy Assessment: Especially important for determining the best access method (touch, switches, eye gaze) for users with physical limitations.
Family Input: AAC works best when it fits seamlessly into the user’s daily life and preferences.
Why Professional Support Matters
A collaborative approach between SLPs, OTs, families, and the AAC user ensures the chosen system supports immediate communication needs while fostering long-term growth and independence.
With the right AAC solution, individuals can:
Express their needs, thoughts, and feelings
Engage in social and educational activities
Build confidence and independence
Whether you choose a low-tech AAC board or a high-tech speech-generating device, the goal is the same — to give every person the ability to communicate effectively. With professional guidance, AAC can open doors, strengthen connections, and make communication possible for everyone.
