CDAC, Mumbai has announced the new release of open source predictive text entry system – Anumaan. This release includes new version of standalone flavour of Anumaan i.e. Anumaan-standalone-0.2. This version has been released as part of the activities of project “Enhancing Accessibility for FOSS Desktops” under NRCFOSS-Phase II being carried out at CDAC, Mumbai.

Anumaan gives predictions based on preceding text/words used by the user in his/her text and user can use these predictions, while composing text. By incorporating predictions, user can improve his/her rate of text entry to a great extent.
