Assistive Technology for Dysarthria | Top AAC Devices for Speech Support

🔊 What Is Dysarthria and Why Assistive Technology Matters

Dysarthria is a motor speech disorder caused by weakness or incoordination of the muscles used for speaking. People with dysarthria often struggle with slurred, soft, or slow speech, making communication difficult.

When speech therapy alone isn’t enough, assistive technology becomes a powerful ally. Tools such as AAC (Augmentative and Alternative Communication) devices and voice-assistive apps help individuals express themselves more effectively, enhancing their independence and confidence.

🧠 What Is AAC?

AAC (Augmentative and Alternative Communication) includes tools and strategies that support or replace spoken communication. AAC can be:

• Unaided (gestures, sign language)

• Aided (devices, communication boards, speech-generating apps)

For individuals with dysarthria, aided AAC tools are often essential.
