What are Speech Generating Devices (SGDs)?
Speech Generating Devices (SGDs) are electronic devices that produce spoken words or phrases when activated. They are used as a form of
augmentative and alternative communication (AAC) for individuals who have severe speech impairments. These devices can be either simple, with pre-recorded messages, or complex, allowing for the creation of novel sentences using a combination of symbols, text, or other inputs.
How Do SGDs Work?
SGDs operate by converting text or symbols into spoken language. Users can select pre-programmed words or phrases using touchscreens, buttons, or other input methods. Advanced SGDs offer features like
text-to-speech technology, customizable voice options, and the ability to store a vast vocabulary. Some devices are portable, while others might be integrated into tablets or computers.
Dedicated devices: Specifically designed for communication purposes and often covered by insurance.
Tablet-based apps: Applications on tablets or smartphones that serve as SGDs. These are often more affordable and customizable.
Hybrid devices: Combine features of both dedicated devices and tablet-based apps.
How to Choose the Right SGD for a Child?
Selecting the appropriate SGD involves a team approach, including input from
speech-language pathologists, occupational therapists, educators, and family members. Factors to consider include the child's cognitive and motor abilities, the specific communication needs, and the environments in which the device will be used. A trial period with different devices can also be beneficial.
Technical issues: Regular maintenance and updates can help ensure the device functions properly.
User training: Ongoing training for both the child and caregivers is essential for effective use.
Social acceptance: Educating peers and educators about the use of SGDs can foster a more inclusive environment.
What is the Future of SGDs in Pediatrics?
The future of SGDs is promising with advancements in
technology and
artificial intelligence. Future devices may offer more intuitive interfaces, better integration with other technologies, and enhanced personalization options. Research continues to explore ways to make these devices more accessible and effective for all children who need them.
