Language transference rule producing apparatus, language transferring apparatus method, and program recording medium

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.
