Abstract

An interactive speech correcting method is provided. The method includes the steps of (a) providing a reference speech, (b) receiving a user speech, (c) analyzing the user speech and the reference speech, (d) creating a speech parameter, (e) proceeding a speech correction by using the speech parameter and the user speech, and (f) outputting a corrected speech.

Claims

1. An interactive speech correcting method, comprising steps of:

(1) providing a reference speech;

(2) receiving a user speech;

(3) analyzing said user speech and said reference speech;

(4) creating a speech parameter;

(5) performing a speech correction by using said speech parameter and said user speech; and

(6) outputting a corrected speech.

2. The method according to claim 1, wherein said step (5) further comprises a contrast between said speech correction and said reference speech.

3. The method according to claim 1, wherein said corrected speech is a corrected said user speech.

4. The method according to claim 1, wherein said reference speech comprises a reference phoneme, a reference length, a reference volume, and a reference intonation.

5. The method according to claim 4, wherein said user speech comprises an original phoneme, an original length, an original volume, and an original intonation.

8. The method according to claim 1, wherein said reference speech has a reference timbre and said user speech has an original timbre, and said step (5) corrects said reference timbre of said reference speech to make it become the same with said original timbre of said user speech to output through said step (6).

6. The method according to claim 6,wherein said step (5) is performed by correcting said original phoneme, said original length, said original volume, and said original intonation on the basis of said reference phoneme, said reference length, said reference volume, and said reference intonation.

7. The method according to claim 6, wherein said step (5) is performed by correcting one selected from the group consisting of said original phoneme, said original length, said original volume, and said original intonation to proceed correcting.

9. An interactive speech correcting method, comprising steps of:

(1) receiving a user speech;

(2) correcting said user speech to form a new user speech; and

(3) outputting said new user speech.

10. The method according to claim 9, wherein said user speech comprises an original phoneme, an original length, an original volume, and an original intonation.

11. The method according to claim 10, wherein said step (2) is based on a reference speech.

12. The method according to claim 11, wherein said reference speech has a reference phoneme, a reference length, a reference volume, and a reference intonation and said step (2) is based on said reference speech.

13. The method according to claim 12, wherein said step (2) further comprises a step (2-1):

correcting one selected from the group consisting of said original phoneme, original length, original volume, and original intonation.

14. The method according to claim 13, wherein said method after said step (2-1) further comprises a step (2-2):

deciding a correcting scale based on said selected item of said step (2-1).

15. The method according to claim 9, wherein said new user speech is a corrected voice of a user.

16. An interactive speech correcting device, comprising:

a speech receiving device receiving an external speech;

a controller connected to said speech receiving device and comprising a reference speech therein; and

a loudspeaker outputting a corrected speech based on said reference speech.

17. The device according to claim 16, wherein said controller comprises a storage device containing said reference speech, said external speech and said corrected speech, and a processing unit electrically connected to said storage device and correcting said external speech to form said corrected speech.

18. The device according to claim 16, wherein said controller separates an original property from said external speech.

19. The device according to claim 18, wherein said original property includes properties of an original phoneme, an original length, an original volume, and an original intonation.

20. The device according to claim 19, wherein said controller only selects a candidate property to be corrected from the group consisting of said original phoneme, said original length, said original volume, and said original intonation properties.

21. The device according to claim 20, wherein said controller further comprises a scale controller performing a staged correction to said candidate property.

22. The device according to claim 20, wherein said reference speech further comprises a reference phoneme, a reference length, a reference volume, and a reference intonation to be a reference for said candidate property.

23. An interactive speech correcting method, characterized in that an outputting standard speech is performed by simulating a user speech.

24. The method according to claim 23, wherein said simulating step comprises steps of:

(1) setting a reference speech;

(2) receiving said user speech; and

(3) producing a corrected user speech by simulating said reference speech based on said user speech.

25. The method according to claim 24, wherein said step (1) further comprises a step (0):

providing a speech parameter.

26. The method according to claim 25, wherein said speech parameter of said step (0) is gained from analyzing said user speech on the basis of said reference speech.

27. The method according to claim 25, wherein said step (2) further comprises a step (2-1):

correcting said speech parameter on the basis of said reference speech.

28. The method according to claim 25, wherein said step (2) further comprises a step (2-2):

segmenting said user speech on the basis of said speech parameter.

29. The method according to claim 28, wherein said segmenting step is performed by cutting a wave pattern of said user speech.

30. The method according to claim 25, wherein said step (2) comprises steps of:

(2-1) correcting said speech parameter on the basis of said reference speech; and

(2-2) segmenting said user speech on the basis of said speech parameter, wherein a sequence of said step (2-1) and said step (2-2) is exchangeable.

31. The method according to claim 24, wherein said reference speech comprises a reference phoneme, a reference length, a reference volume, and a reference intonation.

32. The method according to claim 31, wherein only one from the group consisting of said reference phoneme, said reference length, said reference volume, and said reference intonation is selected to be corrected at a time.

33. The method according to claim 32, further comprising a step of modulating a scale of the selected one.

34. The method according to claim 31, wherein said speech parameter comprises an original phoneme, an original length, an original volume, and an original intonation.

35. The method according to claim 34, wherein only one from the group consisting of said original phoneme, said original length, said original volume, and said original intonation is selected to be corrected at a time.

36. The method according to claim 25, further comprising a step of modulating a scale of the selected one.
