Abstract

Speech data is input from a speech capture unit. External data including vocabulary information is read from an external data acquisition unit. A speech recognition unit makes speech recognition of the speech data using the vocabulary information in the external data and recognition vocabulary information in a recognition vocabulary database, and outputs its speech recognition result.

Claims

1. A speech recognition apparatus for recognizing input speech, comprising:

storage means for storing recognition vocabulary information for speech recognition;

input means for inputting speech data;

read means for reading external data including vocabulary information;

speech recognition means for making speech recognition of the speech data using the vocabulary information in the read external data, and the recognition vocabulary information; and

output means for outputting a speech recognition result of said speech recognition means.

2. The apparatus according to claim 1, wherein the vocabulary information in the read external data contains phonetic information of a word.

3. The apparatus according to claim 1, wherein the external data has a format that allows printing on a recording medium.

4. The apparatus according to claim 3, wherein the external data is a two-dimensional barcode.

5. The apparatus according to claim 3, wherein the external data is an image which contains the vocabulary information generated by a digital watermarking technique.

6. The apparatus according to claim 1, further comprising:

management means for managing the recognition vocabulary information; and

input means for inputting a processing instruction to said management means.

7. The apparatus according to claim 6, wherein said management means deletes at least some items of the recognition vocabulary information on the basis of an instruction input from said input means.

8. A speech recognition method for recognizing input speech, comprising:

an input step of inputting speech data;

a read step of reading external data including vocabulary information;

a speech recognition step of making speech recognition of the speech data using the vocabulary information in the read external data, and recognition vocabulary information stored in a recognition vocabulary database; and

an output step of outputting a speech recognition result of the speech recognition step.

9. The method according to claim 8, wherein the vocabulary information in the read external data contains phonetic information of a word.

10. The method according to claim 8, wherein the external data has a format that allows printing on a recording medium.

11. The method according to claim 10, wherein the external data is a two-dimensional barcode.

12. The method according to claim 10, wherein the external data is an image which contains the vocabulary information generated by a digital watermarking technique.

13. The method according to claim 8, further comprising:

a management step of managing the recognition vocabulary information; and

an input step of inputting a processing instruction to the management step.

14. The method according to claim 13, wherein the management step includes a step of deleting at least some items of the recognition vocabulary information on the basis of an instruction input from the input step.

15. A program for making a computer implement speech recognition for recognizing input speech, comprising:

a program code of an input step of inputting speech data;

a program code of a read step of reading external data including vocabulary information;

a program code of a speech recognition step of making speech recognition of the speech data using the vocabulary information in the read external data, and recognition vocabulary information stored in a recognition vocabulary database; and

a program code of an output step of outputting a speech recognition result of the speech recognition step.
