Is a modified version of Speak.Activity that embeds PyAIML and a chatterbot. It currently supports english and spanish but its simple to add new languages.
By changing the voice's language, you also change the chatterbot's brain.
This quick hack was improvised at the Game Jam Peru 2008 and later refined a bit to make it presentable. It now is in condition to be folded back into Speak if the author so desired.
Its development is tracked at http://wiki.sugarlabs.org/go/Activities/Speak.
