本研究的目的是通过分析不同语音练习过程中下颌骨的最小垂直偏移来确定是否产生了与最近垂直说话空间（CSS）相对应的下颌位置。另一个目标是建立在CSS的变异性产生的个别的咝咝声音素。在三个独立的语音测试期间，使用运动描记器（Sirognathograph，Siemens A.G.，Benshiem，德国）和Bio-Pak（BioResearch Associates Inc.，密尔沃基，WI）的下颌跟踪软件程序。第一个测试是一般语音清晰度测试，包含英语语言的所有声音，特别是包括所有六个咝音单词的声音。第二个语音测试包含组成一个短句的六个咝咝声。第三个测试包括六个单词，每个单词表达不同的咝咝声。在三个练习中确定的平均CSS之间没有统计学显著差异。一个包含所有咝咝声的语音测试产生的CSS相当于一个包含所有语音的测试。CSS的垂直分量也是独立的语音测试的形式或持续时间包含在本调查中使用的咝音单词的声音。在第三次练习中为5个单独的咝音音素确定的CSS与为三次完整练习计算的CSS不同（p < 0.05）。得出的结论是，发出咝咝声音素，或单词的声音，并导致受试者采用CSS。当使用语音测试来确定咬合的垂直维度时，包含所有咝咝声的短持续时间的语音测试似乎给出了对CSS的可靠指导。它还得出结论，受试者不同的组中的嘶嘶声产生的CSS，一个单一的嘶嘶声字的声音不给一个可靠的指示最小的发言垂直尺寸。
The purpose of this investigation was to determine whether the production of sibilant sounds involved adopting a jaw position that corresponded to the closest vertical speaking space (CSS), by analysis of the smallest vertical excursion of the mandible during the performance of different phonetic exercises. A further objective was to establish the variability in the CSS produced by individual sibilant phonemes. Thirty young adult subjects had their CSS determined during three separate phonetic tests, using a kinesiograph (Sirognathograph, Siemens A.G., Benshiem, Germany) and a Bio-Pak (BioResearch Associates Inc., Milwaukee, WI)jaw-tracking software program. The first test was a general phonetic articulation test containing all the sounds of the English language and specifically including all six sibilant word sounds. The second phonetic test contained the six sibilant sounds making up a short sentence. The third test included six single words, each expressing a different sibilant sound. No statistically significant difference among the mean CSS determined in each of the three exercises was demonstrable. A phonetic test containing all sibilant sounds produced a CSS equivalent to that of a test containing all speech sounds. The vertical component of the CSS was also independent of the form or duration of the phonetic tests containing the sibilant word sounds used in this investigation. The CSS determined for 5 of the individual sibilant phonemes in the third exercise differed (p < 0.05) from that calculated for the three complete exercises. It was concluded that voicing sibilant phonemes, or word sounds, does cause the subject to adopt the CSS. When a phonetic test is used in the determination of the vertical dimension of occlusion, one of short duration containing all the sibilant sounds appears to give a reliable guide to the CSS. It was also concluded that subjects varied with respect to which of the group of sibilant sounds produced the CSS, and that a single sibilant word sound does not give a reliable indication of the smallest speaking vertical dimension.
