In this paper, we describe and evaluate recent work and results achieved in a word prediction system for Spanish, applying both statistical and grammatical methods: word pairs and trios, bipos and tripos models, and a stochastic context free grammar. The predictor is included in several software applications, to enhance the typing rate for users with motorical problems, who can only use a switch for writing. These users have difficulties in writing, and usually in communicating with other people, and the inclusion of word prediction in the system allow them to increase their typing rate from 2-3 words per minute up to 8-10 words per minute.
