Individuals who suffer from a stroke or traumatic brain injury may be diagnosed with a speech disorder that impairs the ability to express basic needs and thoughts. The inability to convey a message is often frustrating to both the speaker and listener.

Advances in technology have made it possible for individuals with speech disorders to communicate with others. In an article by Stach (1997), the term augmentative and alternative communication (AAC) refers to "All communication strategies or systems that either augment or replace natural speech". Advances in AAC have boomed in the last decade and are proving to be beneficial to individuals with speech impairments.

AAC systems are categorized as low-tech or high-tech. Low-tech includes alphabet boards, communication books, or any non electronic device. High-tech system include electronic or computerized devices ranging from battery operated to sophisticated computer systems.

The article by Stach (1997) discusses various types of high-tech devices and advances that have been made in this area.
