High Tech Communication Aids with Speech Generation

High tech voice output communication devices. Individuals who need access to a large vocabulary may need a high tech voice output communication device. These devices typically provide access to a large number of messages on multiple overlays. Some devices offer paper-based displays while others offer dynamic displays. These dynamic display communication devices have computer-like displays on which the symbols, words, phrases, or sentences are displayed. Vocabulary is generated by selecting a pre-programmed location or series of locations on the display. This feature allows for rapid access to messages. These devices also typically also include an alphabet display the individual can use to create unique messages that are spoken by the device.¹

Integrated communication solutions. several software-based applications have been developed that enable individuals to use a notebook computer as an augmentative communication device. Most of these devices provide access to picture-based communication displays as well as an alphabet display that can be used to generation novel messages that can be spoken by the device.

Unaided AAC Strategies

Formal Sign Language. This AAC strategy is not device-based, but rather, uses the natural abilities of the individual as a means to build a manual communication system. This form of AAC requires that both the user and all communication partners understand the form of sign language being used. Sign language an effective and efficient AAC strategy IF communication partners are knowledgeable; however, its use frequently requires a back-up system for situations in which the communication partners do not know sign language.

Gestural Systems. These systems are generally non-standard systems that are specific to the actual user of the system. Although there are some gestures that are fairly consistently understood in particular cultures (such as a head nod for yes and a head shake for no) effective and efficient use of a gestural system requires that those with whom the use is communicating be familiar with the gestures and what they mean to this particular user.
