SYSTEM AND METHODS FOR MAINTAINING SPEECH-TO-SPEECH TRANSLATION IN THE FIELD
First Claim
1. A method for updating the vocabulary of a speech translation system for translating a first language into a second language including written and spoken words comprising:
- adding a new word in the first language to a first recognition lexicon of the first language;
associating a description with the new word, wherein the description contains pronunciation and word class information; and
updating the new word and the description in a first machine translation module associated with the first language, wherein the first machine translation module contains a first tagging module, a first translation model and a first language module, and is configured to translate the new word to a corresponding translated word in the second language.

Abstract
A method and apparatus are provided for updating the vocabulary of a speech translation system for translating a first language into a second language including written and spoken words. The method includes adding a new word in the first language to a first recognition lexicon of the first language and associating a description with the new word, wherein the description contains pronunciation and word class information. The new word and description are then updated in a first machine translation module associated with the first language. The first machine translation module contains a first tagging module, a first translation model and a first language module, and is configured to translate the new word to a corresponding translated word in the second language. Optionally, the invention may be used for bidirectional or multi-directional translation

28. A method of machine translation for translating a first language into a second language comprising:
translating a sentence in the first language into a sentence in a second language, wherein the first machine translation module contains a first tagging module, a first translation model and a first language module, and is configured to translate the sentence to a corresponding translated sentence in the second language, wherein a word or word phrase is treated as a class during translation, wherein classes include selected classes from the group consisting of semantic classes, syntactic classes and equivalent word or word phrases. - View Dependent Claims (29, 30, 31, 32)

33. A field maintainable class-based translation apparatus comprising:
a recognition lexicon of a first language configured for accepting sound comprising a new word in the first language and associating a description with the new word, wherein the description contains pronunciation and word class information; and
a first machine translation module associated with the first language comprising a tagging module, a translation model and a language module configured to be updated with the new word and the description.- View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)
