The main objective of the PREDICT4ALL project is to provide written communication in a computer, reducing the number of spelling errors for each user.

The effectiveness of written communication is defined in this study by the number of spelling errors for each user. Word prediction (and therefore correction) must be able to be configured by a therapist (speech therapist, occupational therapist).

Adapting the prediction to user errors should also allow it to be more relevant throughout the text input. This software efficiency must increase text input speed, Reduce the cognitive load, establish a classification of spelling errors adapted to the context of text input speed and develop the word prediction module tolerant of these spelling errors.
