Digital Recording Devices
Digital recording refers to storing messages created by human voice which are played back by the device user to "speak" a given message. These messages sound the same way each time they are played because they are recorded directly onto an electronic storage medium, like a compact flash card. Only messages that have been recorded are available on the device. These are repetitive phrases which can be used as often as needed.
These digital recording devices use static overlays to represent the vocabulary stored on the device. Use symbols, pictures, letters, words, or objects on the overlay to remind the user of the stored message. Change the overlay and set the current vocabulary for that page and speak from recorded messages.
If you want to spell out messages or create novel expressions that have not been recorded, you would need a system capable of text-to-speech, or synthesized speech, found on our Text-to-Speech devices and our Dynamic Display systems.
