Abstract

A speech recognition apparatus includes a document input unit configured to input a document including a reference term which a user refers to; a vocabulary storage unit configured to store a vocabulary list including a group of notation information, reading information and part of speech; a hypernym hyponym relation storage unit configured to store a hypernym hyponym relation tree on a concept between terms; a hypernym acquisition unit configured to search a hypernym of the reference term from the hypernym hyponym relation tree and to acquire the notation information and the part of speech of the hypernym from the vocabulary list; a correspondence storage unit configured to store a correspondence list showing correspondence between the hypernym and the reference term; a display unit configured to display the hypernym; a speech input unit configured to input speech, including the hypernym of the reference term, which the user speaks from the display unit; a speech recognition unit configured to convert the speech into text information by using the vocabulary list; a replacing unit configured to replace the hypernym, which is included in the text information, with the reference term; and an output unit configured to output the text information replaced by the replacing unit.

Claims

1. A speech recognition apparatus, comprising:

a document input unit configured to input a document comprising a reference term which a user refers to;

a vocabulary storage unit configured to store a vocabulary list comprising a group of notation information, reading information, and a part of speech;

a hypernym hyponym relation storage unit configured to store a hypernym hyponym relation tree on a concept between terms;

a hypernym acquisition unit configured to search a hypernym of the reference term from the hypernym hyponym relation tree and to acquire the notation information and the part of speech of the hypernym from the vocabulary list;

a correspondence storage unit configured to store a correspondence list showing correspondence between the hypernym and the reference term;

a display unit configured to display the hypernym;

speech input unit configured to input speech, including the hypernym of the reference term, which the user speaks from the display unit;

a speech recognition unit configured to convert the speech into text information by using the vocabulary list;

a replacing unit configured to replace the hypernym, which is included in the text information, with the reference term; and

an output unit configured to output the text information replaced by the replacing unit.

2. The apparatus according to claim 1, wherein parts of speech of the terms stored by the hypernym hyponym relation tree are nouns.

3. The apparatus according to claim 1, wherein the display unit displays the hypernym which is added to the document.

4. The apparatus according to claim 1, wherein the correspondence storage unit stores identifiers of the hypernym corresponding to each of the reference terms.

5. The apparatus according to claim 4, wherein the display unit displays the hypernym and the identifier.

6. The apparatus according to claim 5, further comprising a detecting unit,

wherein the speech input unit inputs the speech comprising the hypernym and the identifier,

the speech recognition unit converts the speech into the text information,

the detecting unit performs a morphological analysis on the text information and detects the hypernym and the identifier.

7. The apparatus according to claim 6, wherein the replacing unit replaces the hypernym and the identifier with the reference term stored by the correspondence list.

8. The apparatus according to claim 7, wherein the output unit outputs the text information, replaced by the replacing unit, with the identifier being deleted.

9. A speech recognition method, comprising:

inputting a document including a reference term which a user refers to;

storing a vocabulary list comprising a group of notation information, reading information, and a part of speech;

storing a hypernym hyponym relation tree on a concept between terms;

searching a hypernym of the reference term from the hypernym hyponym relation tree;

acquiring the notation information and the part of speech of the hypernym from the vocabulary list;

storing a correspondence list showing correspondence between the hypernym and the reference term;

displaying the hypernym;

inputting speech, comprising the hypernym of the reference term, which the user speaks;

converting the speech into text information by using the vocabulary list;

replacing the hypernym, which is comprised in the text information, with the reference term; and

outputting replaced text information.

10. The method according to claim 9, wherein the reference term is a noun.

11. The method according to claim 9, wherein the reference term is a technical term.

12. The method according to claim 9, wherein correspondence between the hypernym and the reference term comprises identifiers of the hypernym.

13. A computer program product having a computer readable medium comprising programmed instructions for processing text information, wherein the instructions, when executed by a computer, cause the computer to perform:

inputting a document comprising a reference term which a user refers to;

storing a vocabulary list including a group of notation information, reading information, and a part of speech in a vocabulary storage unit;

storing a hypernym hyponym relation tree on a concept between terms in a hypernym hyponym relation storage unit;

searching a hypernym of the reference term from the hypernym hyponym relation tree;

acquiring the notation information and the part of speech of the hypernym from the vocabulary list;

storing a correspondence list showing correspondence between the hypernym and the reference term in a correspondence storage unit;

displaying the hypernym on a display unit;

inputting speech, comprising the hypernym of the reference term, which the user speaks from the display unit;

converting the speech into text information by using the vocabulary list;

replacing the hypernym, which is included in the text information, with the reference term; and

outputting replaced text information.

14. The method according to claim 13, wherein the reference term is a noun.

15. The method according to claim 13, wherein the reference term is a technical term.

16. The method according to claim 13, wherein correspondence between the hypernym and the reference term comprises identifiers of the hypernym.
