Answer 1

You need a text-to-speech (TTS) engine that supports Hindi. Each TTS engine has specific languages that it supports. Here is a TTS engine that supports Hindi, but this runs on Windows. I see from the tags that you want to support this on Android. Here is a post about supporting Hindi TTS on an Android. The native TTS on Android does not support Hindi. What you may have to do is create a service that uses the Hindi text and translates it to an audio file. You would then stream the audio file to your Android application.

In my opinion though you will not want to use TTS for an educational application. I think you will find the output from the TTS very robotic and hard to understand by the students. I would record the lessons/information and just stream it in your application. Before you purchase any TTS engine I would try it out first to make sure that the generated voice is acceptable. Most of the top educational application today (ex: Khan Academy) use pre-recorded audio and/or video.

Answer 2

Answer 3

you should have to use :-

tts.setLanguage(Locale.forLanguageTag("hin-IND"));

or

tts.setLanguage(new Locale("hin","IND",null));
