问题
As I know, TTS needs TTS engine to speak one language. In Android emulator 2.2, Pico TTS engine is default. It has only some popular languages. I can see some engines on Market which must be purchased to install. My question: is there any way to create a custom engine which support other languages?(by programming or using software)
(I don't know if I should post this question in StackOverflow or SuperUser. If wrong place, please migrate it)

I am also interested in making my tts engine. Here are some information I've found. On this link you can find a brief description what you have to do to make your tts engine for android. Since API level 14 there is abstract class for tts engine implementation. More on link.
But making conversion from text to speech isn't so easy. Some basic information what tts engine should implement can be found on wikipedia.
