Description: The VocaFlex is a small, portable, speech generating device (SGD) that is accessed by direct select only. It features one hour of recorded speech capacity, (10-20 seconds per message) and 51 levels. The levels change automatically as the overlays are changed. The overlays have bar-codes that are read by the VocaFlex. When a different overlay is placed on the device, the VocaFlex automatically changes the keyboard configuration and vocabulary to match the overlay. The overlays come in 4, 8 and 16 message configurations.
