To observe the immediate effect of the sounded blowing exercise with semi-occluded vocal tract (SOVTE) in the voices of elderly subjects.
Thirty-three subjects with 65 years of age or older, with no voice or hearing disorder complaints, and with good self-perceived general health participated in the study. All participants filled in a vocal self-evaluation questionnaire. The sustained vowel /ε/ was recorded in three distinct moments: the first, denominated habitual (H), based on the subject's regular production; the second, usage (U), after one minute of continuous spontaneous conversation; the third, exercise (E), carried out after a one-minute execution of the SOVTE. After the exercise, the subjects self-evaluated the changes perceived in their voices. The recordings were edited and randomly paired, considering two moments of the same subject: H/U; H/E and U/E, for further perceptual examination of the better production by three specialized speech-language pathologists.
There were no differences between H and U (p=0.199) and between U and E (p=0.773). However, the E production was considered better than the H production (p=0.004). In the vocal self-evaluation, most subjects (n=25, 75.8%) did not observe immediate effects in their voices after the exercise.
The SOVTE produced positive immediate effects on the vocal quality of elderly subjects, observed only at the perceptual-auditory evaluation.
观察半阻塞声道发声吹气练习（SOVTE）对老年受试者嗓音的即时效果。
33名65岁及以上、无嗓音或听力障碍主诉且自我感觉总体健康状况良好的受试者参与了本研究。所有参与者填写了一份嗓音自我评估问卷。在三个不同时刻记录持续元音/ε/：第一个时刻，称为习惯（H），基于受试者的常规发声；第二个时刻，使用（U），在持续自发对话一分钟后；第三个时刻，练习（E），在进行一分钟的SOVTE后。练习后，受试者对自己嗓音中察觉到的变化进行自我评估。对录音进行编辑并随机配对，考虑同一受试者的两个时刻：H/U；H/E和U/E，以便由三名专业言语病理学家对更好的发声进行进一步的感知检查。
H和U之间（p = 0.199）以及U和E之间（p = 0.773）没有差异。然而，E的发声被认为比H的发声更好（p = 0.004）。在嗓音自我评估中，大多数受试者（n = 25，75.8%）在练习后未察觉到自己嗓音的即时效果。
SOVTE对老年受试者的嗓音质量产生了积极的即时效果，仅在感知听觉评估中观察到。
