Objective To analyze the phonetic features of patients with chronic obstructive pulmonary disease(COPD)by using modern acoustic diagnosis technology,in order to provide an objective basis for the informationized diagnosis of COPD patients in traditional Chinese medicine.Methods The voice signals of COPD group and control group were collected,and the characteristic parameters were extracted by modern speech analysis method to analyze the sound diagnosis characteristics of COPD patients.Results There were significant differences between COPD group and control group(P＜0.05).There were significant differences in the phonetic features of different COPD severity groups(P＜0.05),and showed a certain trend with the change of severity.There were significant differences among different COPD groups(P＜0.05).In pairwise comparison,there were significant differences among the syndrome types(P＜0.05),and they had certain characteristics.Conclusion There are certain rules in the phonetic features of COPD and its different syndromes,which can provide objective reference for the diagnosis of COPD and TCM syndrome differentiation.
