A static display speech generating device (SGD) or communication device is used by an individual to enable him or her to communicate more effectively with others. A device assists an individual in communicating through printed words, speech or voice output, pictures, or any combination of these. Static sets have fixed symbol choices or levels that can be manually changed. Static sets usually have a group of letters, pictures and/or words on an overlay that is inserted or attached to the device. SGDs are designed to be used as a supplementary mode of communication to augment existing communication strategies and can be configured or customized to address most communication needs. All messages are digitized or recorded human speech. Recording time is usually based on cost of the system. The more recording time the more expensive the system is.
Who uses these static or dynamic (computer like) devices?
Individuals who cannot speak, are difficult to understand, or have language retrieval issues might use a SGD. Communication devices are used by people of all ages with a variety of disabilities. An individual with a communication impairment may have difficulty with expressive (what he or she can express) and/or receptive (what he or she understands) communication.
