Thank you so much for replaying, 
But i don’t have Tlite model file. i need to write just a SRS for my FYP. I just need to understand is it feasible to run text to speech in android device using tensor-flow lite.
I know it is possible to build text to speech for English language in Tensor-flow but not sure about Tensor-flow Lite is able to run Text to Speech for Urdu Language in android.
