Language transference rule producing apparatus, language transferring apparatus method, and program recording medium
First Claim
1. A language transferring apparatus characterized in that said apparatus comprises:
- storing means of storing language rules which are obtained by training grammatical or semantic restriction rules for a word or a word string from a training database including a parallel translation corpus in which a source language sentence that is input in a form of speech or text, and that has undergone a corresponding target language transference, is automatically paired with a target language sentence comprising the source language sentence that has undergone the corresponding language transference;
a speech recognizing section which performs speech recognition on input speech by using the stored language rules, and which outputs a result of the recognition in a form of a sentence that is a target language transference;
a language transferring section which transfers the sentence that is the target language transference, into a transferred sentence that has undergone language transference, by using the same language rules as that used in said speech recognizing section; and
a speech synthesizing section configured to aurally output a translation resultant sentence, based on the transferred sentence,wherein said speech recognizing section and said language transferring section perform each processing by dealing with one bundle defined by a style-independent phrase as a common language processing unit.

Abstract
A language transferring apparatus is provided. A language rule producing section statistically automatically trains grammatical or semantic restriction rules for a partial word or a word string from a parallel-translation corpus. The rules are described such that a source language partial sentence corresponds to a target language partial sentence. A speech recognizing section performs speech recognition on source language speech using the language rules and outputs a recognition result. A language transferring section transfers a source language sentence into a target language sentence using the same language rules. Even when a portion of an input speech sentence contains an untrained portion or when speech recognition is partly erroneously performed, transference to the target language is surely enabled. Moreover, a phrase dictionary and interphrase rules which are necessary for transference can be automatically produced without requiring much manual assistance.
