Speech recognition is a pretty hard thing to put in an OLPC, it demands
a lot of computation power. and you need to train a language model per
language, and you need basically a lot of different people reading text.

I tired getting one working in Hebrew using sphinx
( http://en.wikipedia.org/wiki/CMU_Sphinx ), however it seems to be hard
because you need to read a lot of text in to the model, and even then
its hard to make it actually working.

If you still want to try getting this to work i suggest you read more on
sphinx 3 (the numbers are not versions, so make sure its 3). That's the
only open source system I know of that might get it work.
There are still theoretical limitations, like the more words you put it,
the higher the margin of error, and so on.

I hope to see that too! It would be a great thing not only for the
OLPC!, but to everyone!
