@lissyx thank you
I sorted it out
I added zeer, zabar etc in my alphabet.txt file but still error is the same.
I made it for Urdu. Make sure u add all urdu characters, including the characters which are not visible.
@ameerhamza.rz , Hi, You developed for how much hours of data ?
Great. You made it.
For demo, trained it on around 2 hours of corpus (PRUS Corpus + Youtube Videos). Now training it on 75 hours RUMI corpus.
