Which technology is typically used in an aided communication strategy?

In an aided communication strategy, technology is utilized to support or enhance communication for individuals who may have difficulties with spoken language. Text-to-speech devices are a prime example of this kind of technology, as they convert written text into audible speech, allowing users to communicate effectively when they cannot speak or have limited verbal skills. These devices provide a voice for individuals and can range from simple communication boards to sophisticated software applications that allow for customizable speech output.

Other communication methods, such as gestures, eye contact, and natural speech, do not incorporate technology in the same way that text-to-speech devices do. While they are important aspects of non-verbal or supported communication strategies, they do not utilize mechanical or electronic systems to aid communication. Thus, text-to-speech devices stand out as the correct answer, as they directly involve technology to assist communication.
