And step S40, judging whether the start and stop points of the target audio clip are consistent with the positioning start and stop points.
It should be understood that the start point and the stop point of the target audio segment are the start point and the stop point of the target audio segment, that is, the time length of the target audio segment, and by comparing whether the start point and the stop point of the target audio segment are consistent with each other, it can be determined whether the target audio segment is matched with the audio to be corrected, and whether seamless connection is possible, so as to prepare for subsequent audio connection processing.
In a specific implementation, the input mode of positioning the start and stop points in the positioning command may be input through the start and stop time points, or may be input through a left and right start and stop point sliding button, which is not limited in this embodiment.
And step S50, when the start point and the stop point of the target audio clip are consistent with the positioning start point and the stop point, performing splicing processing on the target audio clip and the audio to be corrected to obtain the audio subjected to splicing processing.
It should be noted that, when the start point and the stop point of the target audio segment are consistent with the positioning start point and the stop point, it is stated that the target audio segment is completely matched with the audio to be corrected, audio splicing and splicing processing can be performed, and the target audio segment and the audio to be corrected are subjected to splicing processing, that is, the target audio segment is inserted into the audio to be corrected and audio connection is performed, so that two audio signals are connected into a continuous and smooth audio signal without interruption or jump between the audio signals, so that the two audio signals form a complete audio again, that is, the audio after splicing processing is obtained.

And step S53, connecting the adjusted target audio clip with the audio to be corrected to obtain the spliced audio.
It should be noted that, the pitch parameter, the tone parameter, and the playing speed parameter of the audio to be modified are parameters corresponding to the pitch, the tone, and the playing speed of the audio to be modified, and after the pitch parameter, the tone parameter, and the playing speed parameter of the audio to be modified are obtained, the target audio segment can be correspondingly adjusted according to the pitch parameter, the tone parameter, and the playing speed, that is, the pitch, the tone, and the playing speed of the target audio segment are adjusted to the pitch parameter, the tone parameter, and the playing speed parameter of the audio to be modified, so that the pitch, the tone, and the playing speed of the target audio segment are consistent with the audio to be modified, and of course, the adjustment processing on the target audio segment can process the playing speed, the tone, and the pitch, and can also process the loudness of the target audio segment, so that the adjusted target audio segment and the audio to be modified are kept consistent in auditory perception.
It can be understood that, by adjusting the target audio segment, the pitch, the tone, and the playing speed of the target audio segment may be made to be consistent with the audio to be corrected, so as to splice the adjusted target audio segment and the audio to be corrected, the splicing of the audio may be to splice the adjusted target audio segment and the audio to be corrected in an overlapping and adding manner, or to splice the adjusted target audio segment and the audio to be corrected in an overlapping and storing manner, or to splice the adjusted target audio segment and the audio to be corrected in a linear proportion overlapping manner, or to splice the adjusted target audio segment and the audio to be corrected in other manners, which is not limited in this embodiment, and by connecting the adjusted target audio segment and the audio to be corrected, the auditory perception of the users can be ensured to be consistent, and the interruption or jump generated in the middle of the audio signal is avoided.
