这项研究的目的是批判性地审视一种被称为“哈欠叹息”的声音治疗技术。近年来，浊音叹息作为一种声音治疗方法的使用越来越多，特别是在治疗声音功能亢进问题时。在这项研究中，通过视频鼻内窥镜对八名正常受试者进行了哈欠叹息的生理学研究。还对他们的录音声音进行了声学研究，以了解在正常和叹息条件下产生选定元音时可能出现的基频和共振峰变化。尽管考官给每个受试者提供了一个哈欠叹息的模型，但这八名受试者中有一个无法发出真正的哈欠叹息。八名进行哈欠叹息的受试者中，有七名的内窥镜检查结果显示舌头回缩，喉部位置较低，咽部变宽。对产生叹息的七名受试者的声学分析发现，第二和第三共振峰明显降低。给出了在声音治疗中使用哈欠叹息的含义，例如使用改良的“无声”哈欠叹息，作为产生更大声道放松的简单方法。
The purpose of this study was to take a critical look at a voice therapy technique known as the yawn-sigh. The voiced sigh as an approach in voice therapy has had increased use in recent years, particularly with problems of vocal hyperfunction. In this study, the physiology of the yawn-sigh was studied with video nasoendoscopy in eight normal subjects; their taped voices were also studied acoustically for possible fundamental frequency and formant changes in producing selected vowels under normal and sigh conditions. Although each subject was given a model by the examiner of a yawn-sigh, one of the eight subjects could not produce a true yawn-sigh. Endoscopic findings for seven of the eight subjects performing the yawn-sigh demonstrated retracted elevation of the tongue, a lower positioning of the larynx, and a widened pharynx. Acoustic analyses for the seven subjects producing the sigh found a marked lowering of the second and third formants. Implications for using the yawn-sigh in voice therapy are given, such as using a modified ''silent'' yawn-sigh, as an easy method for producing greater vocal tract relaxation.
