TRANSLATION PROCESSING METHOD AND STORAGE MEDIUM

A translation processing method executed by a computer, the translation processing method includes calculating a first translation probability from each of first phonemes included in a first document described in a first language into each of second phonemes included in a second document, whose contents substantially equivalent to those of the first document, described in a second language and a second translation probability from each of the second phonemes into each of the first phonemes; extracting a phoneme pair in which the first translation probability and the second translation probability are equal to or higher than a threshold value; and generating translation phrases in the first document and the second document based on the extracted phoneme pair.
