Customized Visual Aids for Clearer Communication

Speech-Generating Device (SGD) overlays are custom visual communication layouts placed on communication devices to help individuals express their needs, thoughts, and choices more easily. These overlays are typically static displays with manually inserted pages that may include symbols, photographs, and written words. Selecting an overlay that fits the individual’s communication abilities, needs, and daily environments is essential to ensure the device is effective, meaningful, and easy to use.

What Are Speech Generating Device Overlays?

Speech generating devices are communication tools used in Augmentative and Alternative Communication (AAC). When a person selects a button or symbol on the device, it produces a recorded or synthesized voice message.

Overlays are the visual communication layer placed on top of the device buttons or displayed on the screen. They may include:

• Pictures or symbols

• Words or phrases

• Letters or numbers

• Color-coded choices

• Personalized vocabulary

Each symbol or button corresponds to a specific recorded message or phrase, allowing the individual to communicate quickly and clearly.

Why SGD Overlays Are Important

For many individuals, speaking may be difficult, unreliable, or temporarily unavailable. Without effective communication tools, this can lead to frustration, anxiety, and misunderstandings.

Speech generating device overlays help by:

   •  Supporting clear communication

   •  visual structure and predictability

   •  Increasing participation in conversations

   •  Reducing communication breakdowns

   •  Supporting independence and decision-making

Visual supports make communication faster, easier, and more accessible, especially in busy or high-stress environments.

Vizually Speaking understands that finding time in today’s highly demanding world to create customized visual aids and strategies can be a great challenge. Vizually Speaking is committed to working collaboratively, providing step-by-step support and assisting in the development and implementation of customized visual aids and strategies.

How Overlays Improve Communication

Personalized overlays help individuals communicate more efficiently by organizing vocabulary in a way that makes sense to them.

Examples of communication supported by overlays include:

 ✓  Requesting help or preferred items

 ✓  Making choices

 ✓  Participating in activities

 ✓  Answering questions

 ✓  Expressing feelings or discomfort

 ✓  Engaging in social conversation

Many devices allow multiple overlays or levels, which means vocabulary can be changed to match different situations such as school activities, mealtimes, or community outings.

The Power of Personalization

At Vizually Speaking, customized overlays are designed to reflect the individual’s real life and daily needs.

Personalization may include:

 → Familiar people and caregivers

 → Favorite activities and interests

 → Daily routines

 → Frequently requested items

 → Important functional vocabulary

When communication tools are relevant and meaningful, individuals are more likely to use them consistently and successfully.

Supporting Frontline Workers and Caregivers

Communication challenges can create barriers for those providing care and support. SGD overlays provide a clear and structured way to understand and respond to communication attempts.

They help caregivers and professionals:

   •  Understand needs quickly

   •  Support participation in daily routines

   •  Reduce stress during communication breakdowns

   •  Encourage independence and engagement

These customized visual aids and strategies are especially helpful in healthcare environments, community care, and emergency situations, where clear communication is essential.
