Abstract

A speech recognition apparatus is configured to correct an output recognition result in continuous speech recognition using a physical button (key) to specify the position of a correct portion or an incorrect portion, so that the recognition result can be corrected with simple operation, for visually-impaired users, users who cannot use vision, or in cases where the user is using an apparatus that does not have a display unit.

Claims

1. A speech recognition method, comprising:

a receiving step of receiving speech information;

a speech recognition step of recognizing the speech information received in the receiving step to obtain a recognition result;

an outputting step of outputting the recognition result obtained in the speech recognition step; and

a correcting step of correcting the recognition result output by the outputting step based on re-speak received after accepting a specification of a correct portion in the recognition result via at least one physical key.

2. The speech recognition method according to claim 1, wherein the at least one physical key is a numeric key.

3. The speech recognition method according to claim 1, wherein the correcting step includes a step of specifying the correct portion in order of the recognition result.

4. The speech recognition method according to claim 1, further comprising a recognition constraint addition step of placing a constraint on recognition of a respoken speech based on a result of the correcting step.

5. The speech recognition method according to claim 1, wherein the outputting step includes a step of outputting the recognition result by voice.

6. The speech recognition method according to claim 5, wherein the outputting step includes a step of outputting the recognition result by voice including an auditory signal for indicating separation between units of recognition.

7. A computer-readable medium storing computer-executable instructions for causing a computer to execute the speech recognition method according to claim 1.

8. A speech recognition method, comprising:

a receiving step of receiving speech information;

a speech recognition step of recognizing the speech information received in the receiving step to obtain a recognition result;

an outputting step of outputting the recognition result obtained in the speech recognition step; and

a correcting step of correcting the recognition result output by the outputting step based on re-speak received after accepting a specification of an incorrect portion in the recognition result via at least one physical key.

9. A computer-readable medium storing computer-executable instructions for causing a computer to execute the speech recognition method according to claim 8.

10. A speech recognition method, comprising:

a receiving step of receiving speech information;

a speech recognition step of recognizing the speech information received in the receiving step to obtain a recognition result;

an outputting step of outputting the recognition result obtained in the speech recognition step; and

a correcting step of correcting the recognition result output by the outputting step after accepting a specification of whether the recognition result is correct or incorrect via at least one physical key.

11. The speech recognition method according to claim 10, wherein the outputting step includes a step of sequentially outputting the recognition result in units of recognition, and wherein the correcting step includes a step of specifying whether the recognition result in units of recognition is correct or incorrect via the at least one physical key.

12. The speech recognition method according to claim 10, further comprising a step of conducting re-speak for a misrecognition by voice after specifying with the at least one physical key.

13. A computer-readable medium storing computer-executable instructions for causing a computer to execute the speech recognition method according to claim 10.

14. A speech recognition method, comprising:

a receiving step of receiving speech information;

a speech recognition step of recognizing the speech information received in the receiving step to obtain a recognition result;

an outputting step of outputting the recognition result obtained in the speech recognition step; and

a correcting step of correcting the recognition result output by the outputting step after receiving a specification of an incorrect portion and a type of error in the recognition result via at least one physical key.

15. The speech recognition method according to claim 14, wherein the type of error includes a substitution error, an insertion error, and a deletion error.

16. The speech recognition method according to claim 14, further comprising a specifying step of simultaneously specifying the incorrect portion and the type of error in one continuous operation.

17. A computer-readable medium storing computer-executable instructions for causing a computer to execute the speech recognition method according to claim 14.

18. A speech recognition apparatus, comprising:

a receiving unit configured to receive speech information;

a speech recognition unit configured to recognize the speech information received by the receiving unit to obtain a recognition result;

an output unit configured to output the recognition result obtained by the speech recognition unit; and

a correction unit configured to correct the recognition result output by the output unit based on re-speak received after accepting a specification of a correct portion in the recognition result via at least one physical key.

19. The speech recognition apparatus according to claim 18, wherein the at least one physical key is a numeric key.

20. The speech recognition apparatus according to claim 18, wherein the correction unit is configured to specify the correct portion in order of the recognition result.

21. The speech recognition apparatus according to claim 18, further comprising a recognition constraint addition unit configured to place a constraint on recognition of a respoken speech based on a result obtained by the correction unit.

22. A speech recognition apparatus, comprising:

a receiving unit configured to receive speech information;

a speech recognition unit configured to recognize the speech information received by the receiving unit to obtain a recognition result;

an output unit configured to output the recognition result obtained by the speech recognition unit; and

a correction unit configured to correct the recognition result output by the output unit based on re-speak received after accepting a specification of an incorrect portion in the recognition result via at least one physical key.

23. A speech recognition apparatus, comprising:

a receiving unit configured to receive speech information;

a speech recognition unit configured to recognize the speech information received by the receiving unit to obtain a recognition result;

an output unit configured to output the recognition result obtained by the speech recognition unit; and

a correction unit configured to correct the recognition result output by the output unit by accepting a specification of whether the recognition result is correct or incorrect via at least one physical key.

24. A speech recognition apparatus, comprising:

a receiving unit configured to receive speech information;

a speech recognition unit configured to recognize the speech information received by the receiving unit to obtain a recognition result;

an output unit configured to output the recognition result obtained by the speech recognition unit; and

a correction unit configured to correct the recognition result output by the output unit by accepting a specification of an incorrect portion and a type of error in the recognition result via at least one physical key.
