A
small change in the Speech-ROM but a huge difference in the application. This
medical aid for the voice handicapped persons is based on a children game, the
Touch & Tell.
Dismantling this Vocaid manufactured in July 1984 by Texas Instruments in the United States reveals a design centered around three Integrated Circuits:
• CD8012: 4-bit
TMS1100 microcontroller with 2k Bytes ROM and 128*4 Bits RAM
• TMC0280/CD2802: TMS5110A VSP (Voice Synthesis
Processor)
• TMC0350/CD2357: VSM (Voice Synthesis Memory) with
128k Bits
capacity
The handicapped person places one of the different sheets on the keyboard and with a short finger tip the Vocaid asks for help, shouts for the police or speaks other useful phrases.
Don't miss other talking products for vision impaired - the Calcu-Talk and the Orbit TI-34.
