Embodiment 1
[0029]An embodiment of the present invention provides a human sound signal processing and analysis method.figure 1 The step of the step of the human sound signal processing and the analysis method of one embodiment of the present invention is shown.
[0030]Such asfigure 1 As shown, S11 represents a human voice signal that collects N fixed texts of the L t test repeating M times. In an embodiment of the invention, in particular, the fixing content is said to be fixed by the tester, thereby obtaining the initial data of the human sound signal. Preferably, the number of testers is tested, the number of testers is L; each tester repeats multiple times, the number of repetitions is m; the fixed content includes, but is not limited to vowels, consonants, single words, phrases, etc. And the fixed text is multiple, the number of fixed text is N. Thus, the number of initial data of the human voice signal is L × M × N group.
[0031]S12 represents the processing to obtain the first power spectrum ...
Embodiment 2
[0038]Another embodiment of the present invention provides a human sound signal processing and analysis method. In the present embodiment, "bed", "front", "bright", "month", "light" are read out by the tester, thereby obtaining the initial data of the human sound signal. Preferably, seven testers are tested; each tester repeats 6 times for fixed text content. Thus, the number of initial data of the human body sound signal is 210 groups (5 × 6 × 7).
[0039]The initial power spectral data of the 210 group of human sound signals is obtained through the acquisition and preliminary processing of the initial data of the human sound signal. After the environmental noise is filtered, the power spectrum data of the 210 group of human sound signals is obtained. Combined with modern music theory and traditional Chinese medicine theory, the power spectrum data of each group of human sound signals is divided into the series of frequencies of each of the sounds of each of the sounds, orders, angles...
