Urdu script for Hindi course
Would it be possible to add Urdu script along side the devanagari script for the Hindi course? Since Hindi and urdu are basically the same language (exept for formal hindi which uses all of the tatsama sanskrit loanwords) and in Pakistan they do not use the devanagari script at all.
It would challenge the course developers (whom I think are great, and have done an excellent job!) a lot to do this because they would have to be educated in all the quirks of Arabic script spelling—a tall task to ask from them. All the different varieties of "z" for example. Or inconsistencies like how خوش /xūś/ is the Urdu spelling while ख़ुश /xuś/ is the Hindi one.
Yes, they need developers that are literate in urdu. They can use the same hindi tts, though I do not think it has the /x/ and /ɣ/ sounds of urdu.
One of the problems with the urdu script is that it is mainly written in the nastaliq script, which is different from the more common naskh script that is used to write nearly ever other language in the arabic script. The nastaliq script is not good for computers as it is complicated and fancy, and hard to implement, and only few devices have native support of it, so they would have to settle with naskh.
At least two of the current contributors know the Urdu script, and are familiar with most, if not all its peculiarities. So that is not where the primary difficulty lies. The main issue is that this may not be technologically feasible, because currently there is no way for us to add two scripts for the same course. Although we could try to model an Urdu course after the Hindi course, replacing some of the vocabulary as needed.
