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...

Abstract

The invention provides a human body sound signal processing and analysis method, comprising: step 1, collecting human body sound signals with fixed content and processing to obtain power spectrum data; step 2, dividing the frequency range of the five-tone series, and calculating the frequency range of each sound series Power spectrum data accounts for the proportion of power spectrum data in the frequency range of the five-tone series; Step 3, according to the ratio of each fixed content in the fixed content, assign weights and carry out weighting statistics; Step 4, each fixed content of the fixed content The weighting statistical results of the corresponding sounds are added to obtain the total weight range; step 5, divide the total weight range into weight stages, and summarize the characteristics of the human body according to the characteristics of the sounds in different weight stages. The present invention can describe human voice features more intuitively, comprehensively and accurately.

Description

Technical field[0001]The present invention relates to the field of signal processing analysis, and more particularly to a human sound signal processing and analysis method.Background technique[0002]The sound is an important way to exchange information in human beings, while there is a close relationship between sound and human health. For example, the Chinese medicine theory claims can judge the current health level by identifying the difference between the human current sound signal and the normal state of the human body. Among them, based on five-sound (call, laugh, singing, crying, 呻) and five-sound (angle, conscription, palace, merchants, feather) should have theory of five internal organs (liver, heart, spleen, lung, kidney), Chinese medicine treatment can pass identification Patient speaking sound, language changes, as well as breathing, cough, vomiting, hiccup, 嗳, 嗳, sneeze, bowel, baby crying, etc., foresee changes in human health of the disease.[0003]However, the traditiona...
