Detailed Description

This is an input method engine using scim-tables or ibus-table to look words in a dictionary table. More information about project can be found at

Indic Typing Booster supports currently widely used maps, so the user does not need to switch his existing input maps, like inscirpt, itrans, typewriter. So with this new input method he can type the same way as he did with his older IME's but with prediction.

The mission of this project is to provide user friendly predictive text entry for Indic language users.

Benefit to Fedora

Users can create content in their native language with enhanced speed, accuracy and ease.


After pressing a few characters the user can get the expected word in the candidate list and quickly select that.

Example: Entering the word 'भारतीय' with itrans keyboard normally requires 9 keys presses: 'bhaaratiiy'. With Indic Typing Booster it will only require 6 key presses, after inputting "bhaar" user can get 'भारतीय' in suggestion box, and then just need to press corresponding number key and done.


Since the suggestions come from a validated word dictionary database, the selected words always give 100% accurate spelling. Note: correctly the present generated database is from unreviewed web data, in the long term with community help, they can be reviewed and the correctness checked as per standard. Also infrequent words which may be mis-spellings can be filtered easily from the dictionaries.


Indic scripts are complex since the order of rendering may differ from input order. It has reordering (eg क + ि -> कि ), feature conjunct (eg क + ् + ष -> क्ष), as well as split matras. Often new users are not familiar with these subtleties leading to incorrect or invalid text entry. Indic Typing Booster relaxes this as the user need to enter the complete word.

Adding New Words: One can add new words in to the IME's database, and they will also appear in the suggestion box.

This is easy with scim-tables: type phrase/word and then hit "Ctrl + =", then just enter a corresponding input key, and done.


1) Create dictionary tables from wikipedia dumps for Marathi, Hindi, and Malayalam. More languages will follow later.

2) Fix ibus-table to work well for input with Typing Booster tables.

3) Test with scim-tables and ibus-table.

How To Test

Still not initiated New Package Request

User Experience

1) predictions for entered word. 2) easiness for typing complex words. 3) improved typing speed. 4) Many time native user type language words using latin script (transliteration) so with this IME i think they will type words in there own script.


This feature requires some improvements to be made to ibus-table.

It is already working well with scim-tables.

Contingency Plan

As these are new input methods, no contingency plans necessary.


Release Notes

Indic Typing Booster input methods provide new completing input for Indic languages.
