Embodiment Construction
[0053] The implementation of the present invention will be further described below in conjunction with the accompanying drawings, but the implementation and protection of the present invention are not limited thereto.
[0054] The functional block diagram of the speech scoring device of the dynamic normalized digital feature in this embodiment is as follows image 3 As shown, the target sound needs to be digitized and framed before entering the framing module, so it needs to go through the digitization module and the framing module first. The original sound is directly input to the calculation module. The normalized dynamic features are extracted respectively in the calculation module of the original sound and the target sound. These normalized dynamic features are input to the comparison module for comparison, and the final results are output to the display module.
[0055] A hardware example of the above device is Figure 4 shown. After the user selects the sound signal ...
