Abstract

[Object] The technology that can improve accuracy of speech recognition for collected sound data is provided. [Solution] Provided is an information processing device including: a collected sound data acquisition portion that acquires collected sound data; and an output controller that causes an output portion to output at least whether or not a state of the collected sound data is suitable for speech recognition.

Claims

1. An information processing device comprising:

a collected sound data acquisition portion that acquires collected sound data; and

an output controller that causes an output portion to output at least whether or not a state of the collected sound data is suitable for speech recognition.

2. The information processing device according to claim 1,

wherein the output controller causes the output portion to output whether or not an amount of the collected sound data is within a predetermined allowable range as whether or not the state of the collected sound data is suitable for the speech recognition.

3. The information processing device according to claim 2,

wherein the output controller causes the output portion to output indication of a state in which the collected sound data is not suitable for the speech recognition when the amount of the collected sound data is less than a lower limit of the allowable range.

4. The information processing device according to claim 2,

wherein the output controller causes the output portion to output indication of a state in which the collected sound data is not suitable for the speech recognition when the amount of the collected sound data is greater than an upper limit of the allowable range.

5. The information processing device according to claim 2,

wherein the output controller causes the output portion to output indication of a state in which the collected sound data is suitable for the speech recognition when the amount of the collected sound data is greater than a lower limit of the allowable range and the amount of the collected sound data is less than an upper limit of the allowable range.

6. The information processing device according to claim 2,

wherein the output controller causes the output portion to output at least either of a lower limit and an upper limit of the allowable range.

7. The information processing device according to claim 1,

wherein the output controller causes the output portion to output an amount of the collected sound data.

8. The information processing device according to claim 6,

wherein the amount of the collected sound data includes a temporal length of the collected sound data.

9. The information processing device according to claim 6,

wherein the amount of the collected sound data includes the number of phonemes extracted from the collected sound data.

10. The information processing device according to claim 6,

wherein the amount of the collected sound data includes a temporal length of a speech-like part in the collected sound data.

11. The information processing device according to claim 2,

wherein the output controller updates at least either of a lower limit and an upper limit of the allowable range.

12. The information processing device according to claim 11,

wherein the output controller updates at least either of the lower limit and the upper limit of the allowable range on the basis of an amount of noise.

13. The information processing device according to claim 12,

wherein the output controller updates the upper limit such that the upper limit increases as the amount of noise increases.

14. The information processing device according to claim 1,

wherein the output controller causes the output portion to output whether or not a predetermined expression indicating a beginning of a sentence or an end of a sentence is included in the collected sound data as whether or not the state of the collected sound data is suitable for the speech recognition.

15. The information processing device according to claim 14,

wherein the output controller determines whether or not the predetermined expression is included in the collected sound data on the basis of whether or not the predetermined expression is included in an intermediate result of the speech recognition when the intermediate result is obtained.

16. The information processing device according to claim 1, comprising:

a recognition controller that causes speech recognition for a part or the entirety of the collected sound data to be performed.

17. The information processing device according to claim 16,

wherein the recognition controller determines termination of a part that is a target of the speech recognition on the basis of a timing at which a period of time during which a volume is less than a predetermined volume exceeds a threshold value in the collected sound data.

18. The information processing device according to claim 17,

wherein the output controller updates the threshold value when a predetermined expression indicating a beginning of a sentence or an end of a sentence is included in the collected sound data.

19. A method of information processing, comprising:

acquiring collected sound data; and

causing an output portion to output at least whether or not a state of the collected sound data is suitable for speech recognition.

20. A program that causes a computer to function as an information processing device comprising:

a collected sound data acquisition portion that acquires collected sound data; and

an output controller that causes an output portion to output at least whether or not a state of the collected sound data is suitable for speech recognition.
