Abstract
Method and apparatus for converting language text input into a different language text output. One embodiment may be configured to convert Pinyin into written Chinese language text. Embodiments may provide a language input mechanism that accepts phonetic language input text and generates written language output text, and that also accepts modifications to existing input text and automatically corrects the corresponding output text. Embodiments may display one or more alternative output text words and/or sentences as candidates for the transliteration of the input text. The candidate output words may be ranked according to calculated probabilities, with a most probable candidate appearing first. The user may select from the candidate output text to build an output sentence that represents the correct or preferred transliteration of the input text. A lexicon, language model and history cache of previously selected output text words may be referenced in determining the probabilities of candidate output words.
