I've recently been playing with tuxpaint, gcompris and childsplay. American english kids learn the Sesame Steet alphabet (ayy, bee, cee, dee etc.) UK english kids learn phonics (aa, bur, cur, dur, eff, fur etc). So, I've been translating the sounds in Childsplay and Gcompris.
There is a fantastic tool call normalize-ogg, part of the normalize-audio package.
In a pre-recorded set of oggs, just run
$ normalize-ogg *
Gcompris stores it's alphabet here:
and uses Unicode: a=> U0061.ogg; b=> U0062.ogg etc.
Childsplay stores it's alphabet here:
My alphabet sounds can be found here:
