Those parts are VERY difficult to come by as they've been out of production for a very long time -- but I think www.speechchips.com carries them.

there are programmable oscillators, and some suppliers will pre-program them for you (the programmer is several hundred), but once they are programmed they are non-returnable. I think www.digikey.com will program them, though you'll likely have to call them to request it.

That part used to be carried by Radio Shack in the 1980's, I believe. It was a really nice part, but had too few applications for it. The BS2 could probably use it great. Good luck finding it.

And, having now navigated to www.speechchips.com (http://www.speechchips.com), it looks like they are now available, including a nice small board to put them in, AND the crystal needed.· Including a nice small simulator to run on your PC to get the Phoneme's you'll need to program it.

Really nice!

Thank you for you replys.

Would it be worth trying another DAChttp://forums.parallax.com/images/smilies/idea.gif or it could be a great trouble?http://forums.parallax.com/images/smilies/confused.gif

I'll better make this circuit first and then go on...

Thank you once again,
