Handwriting and voice input with automatic correction
First Claim
1. A method for processing language input in a data processing system, comprising the steps of:
- receiving a plurality of recognition results for a plurality of word components, respectively, for processing a user input of a word of a language, at least one of the plurality of recognition results comprising a plurality of word component candidates and a plurality of probability indicators, the plurality of probability indicators indicating degrees of probability of matching of the plurality of word components to a portion of the user input relative to each other; and
determining one or more word candidates for the user input of the word from the plurality of recognition results and from data indicating probability of usage of a list of words.

Abstract
A hybrid approach to improve handwriting recognition and voice recognition in data process systems is disclosed. In one embodiment, a front end is used to recognize strokes, characters and/or phonemes. The front end returns candidates with relative or absolute probabilities of matching to the input. Based on linguistic characteristics of the language, e.g. alphabetical or ideographic language for the words being entered, e.g. frequency of words and phrases being used, likely part of speech of the word entered, the morphology of the language, or the context in which the word is entered), a back end combines the candidates determined by the front end from inputs for words to match with known words and the probabilities of the use of such words in the current context.
