Questions regarding TX/RX & sound IC

I try to build a device which is useful for the visually impaired person.
The deveice can help them to know the bus number and where actually the bus heading for through a speaker placed at the bus station.
The bus hv a transmitter and the bus stop hv a receiver.

my question is what are the TX and RX suitable for this kind of projects?

What is the types of sound IC to use?

Do i need microcontroller on both sides of the TX and RX? If possible inform me what types of controller that is suitable.....

TQ for those who are willing 2 answers my ques....
Quite a lot

Are you a beginner in electronics?

Yes and no....

Actually i have some concept and planning to use what microcontroller.

I need some opinions from experts and compare which one is better..

Thanks for replying....

I would go with a PIC microcontroller
and a eeprom from microchip.

How about the type of sound to be used?

Can u post me the data sheets of the PIC u recommended to me?

OK, PICs are very universal... Please read "Read this!" in my signature. You should start with 16F628(18pin) or with 16F877(40pin) PIC.
