voice announcement

Hi

Iam doing number display using wire less communication.

Whatever numbers I pressed on the keypad (transmitter side) should be

displayed on the 7-segment display (receiver side).

My doubt is how to convert the displayed numbers on the 7-segment in to

the voice announcement.

Ex: if I displayed 2 5 9 numbers on the 7-segment display the

announcement should be in voice Like TWO FIVE NINE.

Please suggest suitable voice chips and related projects for above project.

Thank you

Regards

Look into Winbond voice chips call ISD ChipCorder. They carry serial and parallel interfaces. You may record small packets of sounds and have each one at an address you choice. Then when a particular number is received, invoked the sound representing the number at predefined address.

I suggest a 10 or 20 second device in serial interface as a starter.
