An acoustical analysis of the speaking and singing voices of two types of professional singers was conducted. The vowels /i/, /a/, and /o/ were spoken and sung ten times each by seven opera and seven country and western singers. Vowel spectra were derived by computer software techniques allowing quantitative assessment of formant structure (F1-F4), relative amplitude of resonance peaks (F1-F4), fundamental frequency, and harmonic high frequency energy. Formant analysis was the most effective parameter differentiating the two groups. Only opera singers lowered their fourth formant creating a wide-band resonance area (approximately 2,800 Hz) corresponding to the well-known "singing formant." Country and western singers revealed similar resonatory voice characteristics for both spoken and sung output. These results implicate faulty vocal technique in country and western singers as a contributory reason for vocal abuse/fatigue.
对两类职业歌手的说话和唱歌声音进行了声学分析。七位歌剧歌手和七位乡村与西部歌手分别对元音/i/、/a/和/o/各进行了十次说话和演唱。通过计算机软件技术得出元音频谱，从而能够对共振峰结构（F1 - F4）、共振峰（F1 - F4）的相对振幅、基频和谐波高频能量进行定量评估。共振峰分析是区分这两组歌手的最有效参数。只有歌剧歌手降低了他们的第四共振峰，形成了一个宽带共振区域（约2800赫兹），这与著名的“歌唱共振峰”相对应。乡村与西部歌手在说话和演唱输出中表现出相似的共振声音特征。这些结果表明，乡村与西部歌手发声技巧存在缺陷是导致嗓音滥用/疲劳的一个原因。
