Hello Matt,

Thank you very much for such a long and detailed explanation, it must have been a pain to type so much.
I am planning to introduce speech in a water level controller and all I want it to announce the following: "Sump Empty" "Tank Full" "Dry-Run" etc.
These messages could be stored in the ROM (program memeory area).
I was wondering if there could be special speech chips such as the SPO-256, (I heard about this chip years ago but never got to use one)
which could reduce the load on the microcontrollers and allow me use the smaller microcontrollers.
I would be thankfull, if you can email those data sheets and other details. ( email:mercyjohn@hotmail.com).

Hello Steve,

Can you please throw more light on the ISD chipcorder?

Regards,
John.
