中醫聞診現代化研究(三)--陽虛患者之語音分析

中醫聞診以患者聲音之變化協助診斷，為臨床辨症重要的一環，但其作業過程缺乏客觀之標準；經本研究小組對「氣虛」與「陰虛」患者語音分析取得初步結果之後，更加強了對中醫聞診客觀標準化的信心。

故本研究小組繼「氣虛」與「陰虛」患者語音分析研究之後，再以「陽虛」患者為對象，借助現代語音分析之技術，對其聲音加以分析，以瞭解「陽虛」患者聞診辨症的微觀變化。

在中國醫藥學院附設醫院中醫門診篩選陽虛患者40名為實驗組，另40名非虛者為對照組，錄取母音/a/一短聲，每一短聲約一秒鐘，將錄取之有效聲波分成八等分，擷取有效語音之前段、中段及後段之語音波形作分析，亦即取其1/8、4/8、6/8處之波，每處由波峰起取200msec長度（約十個週期波），依次定義為B（begin）波、M（medium）波、及E（end）波，對其第一、第二共振頻與基頻加以比較分析。

初步觀察顯示「陽虛」患者之語音分析具有「氣虛」患者在語音分析上之特點，但基頻有飄移的現象為其特點。

Modernization of listening examination in Chinese Medicine (III) –Analysis of Yang-vacuity voice

Auscultation using the patient’s voice changes for diagnosis is an essential issue in traditional Chinese medicine. However, its procedure fell short of objective standard, and it never underwent precise measurement and testing. This study, involving modern techniques of voice analysis, was applied to yang-vacuity patients in order to understand their microscopic auscultatory changes.

Forty yang-vacuity patients screened from our clinic of Chinese medical department were taken as the study group, while another 40 non-vacuity patients as control group. We recorded the vowel /a/ in one short note lasting about 1 second. By dividing the recorded voice utterance into 8 segments, we took the early, middle and late part of the sound wave from the voice utterance for analysis. That is, from the 1/8, 4/8 and 6/8 segments of the wave, each from peak of wave to about 200 msec, we defined them as B wave, M wave and E wave.
