Some methods for direct measurement of subglottal pressure during speech are invasive and thus cannot be used on a routine basis. The development of noninvasive techniques is thus desirable, and a simple indirect method for measuring subglottal pressure from records of oral pressure during consonants has recently been proposed and applied to studies of glottal resistance during phonation. In order to bae useful, indirect measurement procedures should be validated by comparisons with direct measurements, and the present experiment was designed for such a comparison. Miniature pressure transducers were used to obtain records of pressure below and above the glottis. Results showed nonsignificant differences and a high correlation between the direct and indirect measurements. This indirect method for measuring subglottal pressure thus appears to provide valid results.
一些在言语过程中直接测量声门下压力的方法具有侵入性,因此无法常规使用。因此,开发非侵入性技术是很有必要的,最近有人提出了一种从辅音期间的口腔压力记录中测量声门下压力的简单间接方法,并将其应用于发声时声门阻力的研究。为了有用,间接测量程序应该通过与直接测量进行比较来验证,而本实验就是为了进行这种比较而设计的。使用微型压力传感器来获取声门上下的压力记录。结果显示直接测量和间接测量之间没有显著差异,且相关性很高。因此,这种测量声门下压力的间接方法似乎能提供有效的结果。
