Immediate effects of an exercise with the vocal tract semi-closed.
To investigate the immediate effects of the phonation exercise in a straw in individuals with and without vocal fold lesions.
Prospective study. 48 individuals, aged between 18 and 55 years participated in the study, and they were distributed into two groups: GL- with a benign vocal fold lesion; GSL- without a lesion. The following analyses were carried out before and after the straw phonation exercises: voice self-analysis, [ε] vowel auditory-perception analysis, selected parameters acoustics (VoxMetria 2. 6) and videolaryngoscopy.
The vocal self assessment indicated a statistically significant improvement on voice emission in GL individuals (p = 0. 015). There were no statistically significant differences before and after the exercise and between the groups, in the videolaryngoscopy, acoustic and auditory-perception assessments.
The straw phonation exercise caused positive effects, seen upon voice self-assessment, indicating an easier and better voice upon phonation.
声道半闭运动的即时效果。
研究在声带病变患者和无声带病变患者中，使用吸管发音练习的即时效果。
前瞻性研究。48 名年龄在 18 至 55 岁之间的个体参与了这项研究，他们被分为两组：GL-良性声带病变；GSL-无病变。在吸管发音练习前后进行了以下分析：嗓音自我分析、[ε]元音听觉感知分析、选择的声学参数（VoxMetria 2.6）和视频喉镜检查。
GL 个体的嗓音自我评估表明，在嗓音发声方面有统计学意义的显著改善（p = 0.015）。在练习前后以及两组之间，视频喉镜、声学和听觉感知评估均无统计学差异。
吸管发音练习在嗓音自我评估中产生了积极的效果，表明发音时声音更容易且更好。
