【摘要】：目的:了解专业歌手同普通人嗓音计算机分析中持续/a/音和/i/音的差别。方法:30例经过声乐专业训练的专业歌手(专业组),男15例,年龄(22.5±1.6)岁;女15例,年龄(22.7±2.5)岁。正常普通人30例(普通组),男16例,年龄(30.9±4.7)岁;女14例,年龄(29.0±3.8)岁。在隔声室中使用德国Xion公司的头戴式麦克风录音,研究对象发持续/a/音和/i/音各3遍,选取中间平稳段3s作为分析段。使用Praat嗓音分析软件进行分析。取基频均数(F0)、频率微扰Jitter、振幅微扰Shimmer、噪谐比、谐噪比强度作为测试值,使用独立样本T检验统计专业组和普通组以及持续/a/音和/i/音之间的差别。Pearson相关检测持续/a/音和/i/音之间的相关性。结果:持续/a/音和/i/音的Shimmer值,普通组大于专业组(P0.01)。专业组男性发持续/a/音和/i/音的基频均高于普通组(均P0.05)。专业组F0值、Shimmer值及噪谐比/i/音明显大于/a/音(均P0.01),Jitter值及谐噪比强度/i/音小于/a/音(均P0.05)。普通组Jitter值2个元音无差别,其余指标同专业组。专业组的/i/-/a/音谐噪比强度差值较普通组大(P0.05)。专业组持续/a/音和/i/音的F0、Jitter值、噪谐比和谐噪比强度显著相关(均P0.05)。普通组持续/a/音和/i/音之间F0、谐噪比强度显著相关(均P0.01)。结论:专业组男性发/a/音和/i/音的基频均高于普通组,前后元音的杂音均少于普通组。专业组选择/a/音或/i/音均可作为测试音,两者区别不大。
[Abstract]:Objective: to understand the differences of continuous / / / and / or / or / / sound in the computer analysis of voice between professional singers and ordinary people. Methods: thirty professional singers (15 males, aged 22.5 卤1.6) and 15 females trained professionally in vocal music were studied. The age was 22. 7 卤2. 5 years old. There were 30 normal people (normal group, 16 males, aged 30.9 卤4. 7) and 14 females, aged 29. 0 卤3. 8 years. In the sound-insulation room, the subjects used the head-mounted microphone of Xion Company of Germany to record the sound. The intermediate stationary segment 3s was selected as the analysis segment. The Praat voice analysis software was used. The fundamental frequency mean (F0), the frequency perturbation (JIT), the amplitude perturbation Shimmer, the noise to harmonic ratio, the harmonic to noise ratio and the intensity of the harmonic to noise ratio were taken as the test values. Independent sample T was used to test the differences between the professional group and the normal group, as well as between continuous / / sound and / or / or / / / tone. Pearson correlation was used to test the correlation between continuous / / sound and / or / or / or / or / or / or /. Results: the Shimmer value of continuous / continuous / / / and / or / or / or / or / or continuous / r / I / sound. The fundamental frequencies of the males in the normal group were higher than those in the normal group (P0.05). The F0 value and the ratio of noise to harmonic ratio / I / I / sound in the professional group were significantly higher than that in the / R group (both P0.01 / Jitter and the harmonic / noise ratio / intensity) were lower than / / / sound (P < 0.05) (all P0.01 / Jitter and the intensity of harmonic / noise ratio) were lower than that of / / sound (P < 0.05) (all P0.01Jitter and the intensity of harmonic / noise ratio were lower than / a / sound). There was no difference in Jitter between two vowels. The rest of the indexes were the same as those in the professional group. The difference in the intensity of the / / r / r / a / tone harmonic / noise ratio of the professional group was larger than that of the ordinary group (P 0.05). The F0 / Jitter value of the professional group continued to be a / R / R / R / I / sound. There was significant correlation between harmonic ratio and harmonic noise ratio (all P0.05). F0 and harmonic / noise intensity were significantly correlated between continuous / / sound and / or / or / or / or tone in normal group (P < 0.01). Conclusion: the fundamental frequencies of / / sound and / or / or / or tone in professional group are higher than those in normal group. The number of vowels was less than that of the normal group, and the professional group chose either / a / or / / / as the test sound, but there was no significant difference between the two groups.
