Google Transliteration IME is an input method editor which allows users to enter text in one of the supported languages using a roman keyboard. Users can type a word the way it sounds using Latin characters and Google Transliteration IME will convert the word to its native script. Note that this is not the same as translation — it is the sound of the words that is converted from one alphabet to the other, not their meaning. Converted content will always be in Unicode. For example, typing “hamesha” transliterates into Hindi as: 
and typing “salaam” transliterates into Persian as:

Google Transliteration IME
Google’s service for Indic languages was previously available as an online text editor, named Google Indic Transliteration. Other language transliteration capabilities were added (beyond just Indic languages) and it was renamed simply Google transliteration. Later on, because of its steady rise in popularity, it was released as Google Transliteration IME for offline use in December 2009.
It works on a dictionary-based phonetic transliteration approach, which means that whatever you type in Latin characters, it matches the characters with its dictionary and transliterates them. It also gives suggestions for matching words. Read more …… / Refer Facebook
