Abstract
A computerized system performs word recognition. It does pattern matching to select which vocabulary words appears, according to the pattern matching, to most probably correspond to word signals it seeks to recognize. It produces an output corresponding to the vocabulary words selected at a movable cursor position in a body of text. The system improves its recognition by obtaining information about the linguistic context of the current cursor position in the body of text and using that information to vary the probability of which one or more words is selected by its pattern matching. The pattern matching can be speech recognition performed on signals representing the sound of spoken words. In some embodiments, the word recognition is executed on a computer system capable of running multiple programs at once; the recognized word is output to another program for insertion at a cursor position in that other program; and the linguistic context information is obtained from data structures created by the other program.
