Method, apparatus, system, and computer program product for machine translation

A machine translation system comprising:

• a display apparatus that displays a source language document described in a source language;
• and
• a machine translation apparatus that translates the source language document into a translated document described in a target language as a translation result, and that is connected to the display apparatus via a network, wherein
• the machine translation apparatus includes:
• a document receiving unit that receives an input of the source language document;
• a translating unit that translates the source language document into the translated document, and creates an ambiguous portion that is a word or a sentence having an ambiguity occurred during translation;
• a storing unit that stores the translated document and the ambiguous portion;
• a speech receiving unit that receives a speech in the source language;
• a recognition unit that recognizes the speech received by the speech receiving unit and creates a source language speech sentence as a recognition result;
• a translation updating unit that updates the translated language document stored in the storing unit by retranslating a part of a speech content of the source language speech sentence to which the ambiguous portion corresponds, when the source language document includes the ambiguous portion;
• a first display control unit that displays the translated document updated by the translation updating unit on a first display unit;
• and
• a transmitting unit that transmits the ambiguous portion stored in the storing unit to the display apparatus, and
• the display apparatus includes:
• a receiving unit that receives the ambiguous portion from the machine translation apparatus;
• and
• a second display control unit that displays the source language document on a second display unit, the source language document including information for indicating occurrence of the ambiguous portion where the ambiguity occurs based on the ambiguous portion received by the receiving unit.

A machine translation method comprising:

• receiving an input of a source language document described in a source language;
• translating the source language document into a translated document described in a target language, and creating an ambiguous portion that is a word or a sentence having an ambiguity occurred during translation;
• storing the translated document and the ambiguous portion in a storing unit;
• receiving a speech in the source language;
• recognizing the speech and creating a source language speech sentence as a recognition result;
• updating the translated language document stored in the storing unit by retranslating a part of a speech content of the source language speech sentence to which the ambiguous portion corresponds, when the source language document includes the ambiguous portion;
• and
• displaying the translated document updated in the updating on a display unit.

A computer program product having a computer readable medium including programmed instructions for machine translation, wherein the instructions, when executed by a computer, cause the computer to perform:

• receiving an input of a source language document described in a source language;
• translating the source language document into a translated document described in a target language, and creating an ambiguous portion that is a word or a sentence having an ambiguity occurred during translation;
• storing the translated document and the ambiguous portion in a storing unit;
• receiving a speech in the source language;
• recognizing the speech and creating a source language speech sentence as a recognition result;
• updating the translated language document stored in the storing unit by retranslating a part of a speech content of the source language speech sentence to which the ambiguous portion corresponds, when the source language document includes the ambiguous portion;
• and
• displaying the translated document updated in the updating on a display unit.
