how to convert every charecter which I have typed into required language

I am using ml kit for translation but in my case I dont need translation I just need Transliteration for example if I type 'H' it need to show in required language script ,so every word need to convert dont translate. I just need to change the scrpt language which user writen.
Example in hindhi languge(hi):
1.hello -हेलो
2.h - एच

**Mobile environment**
Android,

Edit: I excatly need 'Transliteration' not translation
