Text to speech in Tajik Language

Dear Khbegim,
I want to tell you that there's nothing impossible, but creating a text to speech engine is an operation that takes a lot of work and time and probably it doesn't depend on your stored voice because there's a lot and unexpected words the user may write for the program to say.
But if you want the program to say several words(Constant words) you can record these words and make the program open the recorded voice file at the time you want.

This is what I think, but I advice you to look for more researches about creating a Text to Speech engine.

I forgot to mention that, sorry:

You can record every letter alone and sum them together when the user types a word.
for example I'll store the letter G,O,L,E and when the user types Google the program should play recorded letters fast.
Creating a speech engine requires a knowledgeable person of the language.
