adding primitive dubbing information to the audio information according to the dubbing instruction.

4. The method for producing the audio file according to claim 1, wherein, after the recording the user'"'"'s voice to obtain audio information, the method further comprises:

displaying an operation icon that corresponds to the audio information; and

performing playing control on the audio information according to an operation performed by the user on the operation icon.

5. The method for producing the audio file according to claim 4, wherein the performing playing control on the audio information according to the operation performed by the user on the operation icon comprises:

controlling going forward or going backward of a playing position of the audio information according to an operation that the user turns the operation icon.

6. The method for producing the audio file according to claim 4, wherein the performing playing control on the audio information according to the operation performed by the user on the operation icon comprises:

controlling playing or pausing of the audio information according to an operation that the user clicks the operation icon.

7. The method for producing the audio file according to claim 1, wherein, after the generating the score curve according to the audio information, and displaying the score curve, the method further comprises:

receiving a remark adding instruction that is sent by the user by executing a preset second operation of selecting a remark position from the score curve;

displaying an input box for the user to enter remark content; and

receiving the remark content entered by the user in the input box.

8. The method according to claim 1, wherein receiving the polishing instruction that is sent by the user by operating the score curve and adjusting the audio information according to the polishing instruction are implemented according to the first procedure.

9. The method according to claim 1, wherein receiving the polishing instruction that is sent by the user by operating the score curve and adjusting the audio information according to the polishing instruction are implemented according to the second procedure.

10. The method according to claim 1, wherein receiving the polishing instruction that is sent by the user by operating the score curve and adjusting the audio information according to the polishing instruction are implemented according to the third procedure.

11. A terminal device, comprising:
