UNLABELLED
Immediate effects of an exercise with the vocal tract semi-closed.
OBJECTIVE
To investigate the immediate effects of the phonation exercise in a straw in individuals with and without vocal fold lesions.
MATERIALS AND METHODS
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.
RESULTS
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.
CONCLUSIONS
The straw phonation exercise caused positive effects, seen upon voice self-assessment, indicating an easier and better voice upon phonation.

目的
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。
材料和方法
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。
结果
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。
结论
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。
