Abstract

When a voice of the user cannot be recognized, a voice recognition device automatically switches to a voice command registration mode. In the voice command registration mode, the user is caused to select a desired processing, the unrecognized voice is registered, and the desired processing is executed.

Claims

1. A voice recognition device comprising:

a voice recognition unit that performs voice recognition with respect to a voice of a user;

an errata determination unit that determines whether the voice recognition is successful;

a processing selection unit that causes the user to select a processing corresponding to the voice when the errata determination unit determines that the voice recognition is unsuccessful;

a voice registration unit that registers the voice as a voice command to execute the processing selected; and

an execution command unit that commands execution of the processing.

2. The voice recognition device according to claim 1, wherein the execution command unit commands execution of a processing that corresponds to the voice for which the voice recognition is successful.

3. The voice recognition device according to claim 2, further comprising a speaker adaptation unit that performs a processing to improve a recognition rate of the voice for which the voice recognition is successful.

4. The voice recognition device according to claim 2, further comprising:

a storage unit that stores a table including predetermined processings and corresponding voices; and

a speaker adaptation unit that performs a processing, when the voice recognition is successful, to adapt a predetermined processing in the table corresponding to the voice so as to improve a recognition rate of the user'"'"'s voice.

5. The voice recognition device according to claim 1, further comprising a presentation unit that presents to the user, before the voice registration unit registers the voice, contents that are already registered.

6. A voice recognition method comprising:

performing voice recognition with respect to a voice of a user;

determining whether the voice recognition is successful;

causing the user to select a processing corresponding to the voice for which the voice recognition is unsuccessful;

registering the voice as a voice command to execute the processing selected; and

commanding execution of the processing.

7. The voice recognition method according to claim 6, wherein a processing that corresponds to the voice is commanded at the commanding when the voice recognition is successful.

8. The voice recognition method according to claim 7, further comprising performing a processing to improve a recognition rate of the voice for which the voice recognition is successful.

9. The voice recognition method according to claim 7, further comprising:

storing a table including predetermined processings and corresponding voices; and

performing a processing, when the voice recognition is successful, to adapt a predetermined processing in the table corresponding to the voice so as to improve a recognition rate of the user'"'"'s voice.

10. The voice recognition method according to claim 6, further comprising presenting to the user, before the voice is registered at the registering, contents that are already registered.

11. A computer-readable recording medium that stores therein a computer program that causes a computer to execute:

performing voice recognition with respect to a voice of a user;

determining whether the voice recognition is successful;

causing the user to select a processing corresponding to the voice for which the voice recognition is unsuccessful;

registering the voice as a voice command to execute the processing selected; and

commanding execution of the processing.

12. The computer-readable recording medium according to claim 11, wherein a processing that corresponds to the voice is commanded at the commanding when the voice recognition is successful.

13. The computer-readable recording medium according to claim 12, wherein the computer program further causes the computer to execute performing a processing to improve a recognition rate of the voice for which the voice recognition is successful.

14. The computer-readable recording medium according to claim 12, wherein the computer program further causes the computer to execute:

storing a table including predetermined processings and corresponding voices; and

performing a processing, when the voice recognition is successful, to adapt a predetermined processing in the table corresponding to the voice so as to improve a recognition rate of the user'"'"'s voice.

15. The computer-readable recording medium according to claim 11, wherein the computer program further causes the computer to execute presenting to the user, before the voice is registered at the registering, contents that are already registered.
