What will be an ideal response?
Ans: When considering technology for pupils with speech and language impairments it is typically for students who have complex communication needs such as individuals with severe speech and language impairments, autism spectrum disorder, or intellectual disability. Technology use for these students is referred to as augmentative and alternative communication (AAc. . AAC includes all forms of communication (other than oral speech) that are used to express thoughts, needs, wants, and ideas. AAC devices enhance or serve as an alternative to a student’s communication.
Low-tech AAC includes the use of picture symbols. With picture symbols students often use a communication board or book to select symbols to communicate. Mid-tech and high-tech AAC involves the selection of symbols or words to generate speech, using devices referred to as speech generating devices. With mid-tech AAC, typically another individual records a finite set of words or phrases that a student can then select to communicate. With high-tech AAC, a pupil selects symbols or words to produce synthesized speech. Increasingly, AAC is using mobile technologies, such as tablets and smartphones.
