The technique of "placing" the voice in the throat, head, or elsewhere is used in training singers of operatic quality and in vocal rehabilitation. A vocal tract model of placement has been shown to have perceptual validity (Nichols and Shellenberger, 1985). This study tested its acoustic validity. Line spectra of vowels at different vocal placements were analyzed. We found that Formant 2 reflected changes in vocal placement for both male and female speakers.
将声音“放置”在喉咙、头部或其他部位的技巧被用于培养具有歌剧演唱水平的歌手以及嗓音康复训练中。一种关于发声位置的声道模型已被证明具有感知效度（ Nichols和Shellenberger，1985年）。本研究测试了其声学效度。分析了不同发声位置的元音的线谱。我们发现，对于男性和女性说话者而言，第二共振峰都反映了发声位置的变化。
