How would I Record an original song onto a Greeting card computer chip / transistor / speaker Answered

I received a Hallmark Greeting card which played a song when opened. I want to record an original song and make my own singing cards. How would I do this? Does anyone know a manufacturer?

Recently I  came across a whole slew of the cards that allow recording of music or voice, at a discount card display at some store....I kick myself for not getting a bunch of them at the time; because now I can't remember where they were (which store)....they were like a buck a piece which is cheaper then the chips cost....

There are cards that will record your voice and play it back when opened. Quality wasn't great on the last one I received, but voices were recognizable so it wasn't that bad. At a chip level, a company named ISD developed a set of chips that do this and are controlled by assorted means. They're currently available as Winbod ChipCorder chips. (12kHz max sample rate.)

I guess that this technology is now available from "Nuvoton":

Thanks. The Hallmark Card had the Hallelujia Chorus on it with great quality. I'm looking for that.

Yeah, they put that chip in a number of things, including some picture frames, etc. As westfw suggests, it would be cheaper to get the chip directly IF you can.
