Purpose: to evaluate the reliability of the maximum phonation time (MPT) and Vital Capacity intra and inter-examiner, by means of the single-breath counting test (CT) and the sustained /a/ phoneme, and the slow vital capacity (SVC). Methods: a reliability study carried out in three groups of healthy individuals, each group with 30 volunteers, allocated according to age. SVC was measured using a spirometer, while the MPT was assessed by the phoneme /a/ and CT. The data were analyzed using SPSS version 20.0. Initially, descriptive statistics were used and for data reliability, the intraclass correlation coefficient (ICC). Results: the Intraclass Correlation Coefficients (ICC) were considered excellent, with significant results above 0.92 for SVC and greater than 0.79 for CT and phoneme /a/. Regarding the inter-examiner evaluation, the ICCs were also significant for both SVC with values greater than 0.96, and for CT and the phoneme /a/ with values greater than 0.85. The error inherent in the technique was assessed using the standard error of the measurement for intra and inter-examiner analyses with values ranging from 1.79 to 3.29 for phoneme /a/, 3.20 to 6.58 for CT and 65, 05 to 206.73 for SVCml. Conclusion: phonation techniques with the phoneme /a/ and CT, as well as SVC, have an excellent reliability, due to intra and inter-examiner agreement measures.

“…The article itself opens up future possibilities, so that the single-breath counting test can be used to estimate SVC and monitor disease evolution in patients presented with COVID-19 SBC is a test in which individuals are asked to inhale as much air as possible and, during exhalation, to start counting numbers in an ascending order, starting with the number one to the largest number they can reach, in a single exhalation, maintaining the tone and intensity of a habitual phonation 2,3 . As lung function is directly related to voice production, individuals with limited lung functionality may have an altered SBC [2][3][4][5][6] . In addition, as it is a technique that makes it possible to quantitatively assess the emission, it is possible to develop research that compares pre and post treatment values, in different populations and in monitoring the disease's evolution.…”

“…In addition, control of the infection was further impaired by the limited number of specific facilities for the admission of COVID-19 positive patients 7 . Furthermore, the assessment of hospitalized patients and the use of specific equipment to check lung function, such as spirometer/ventilometer, requiring qualified professionals to apply, disinfect and dispose materials, makes the use of standard procedures very costly and difficult to put into effect 4,8,11 .…”

“…For over 10 years, a group of Brazilian researchers has studied the relationship between SVC and SBC [2][3][4]12,13 , identifying a positive correlation both in hospitalized patients 12 and in young people without respiratory complaints 13 . Another important study group 3 evaluated an estimate of SVC from SVC in 221 hospitalized individuals.…”

Introduction The voice and hearing can be affected to different degrees by aging, which can cause communication difficulties for elderly people. Vocal production requires effective temporal auditory processing at central levels within the nervous system, which can be compromised by the aging process. Objective To analyze the correlation between voice and temporal auditory processing in older adults. Materials and Methods A total of 40 elderly people aged 60 years or older were subdivided into 2 groups according to the presence or absence of vocal symptoms measured by the Voice Symptom Scale. All of the participants were submitted to auditory temporal tests, vocal self-assessment, and acoustic and perceptual auditory analyses of voice. Results Most of the subjects assessed had decreased voice intensity and normal variability in terms of vocal quality. The performance was normal in the Pitch Pattern Sequence test and altered in the Random Gap Detection test. In the Masking Period Pattern test, the detection thresholds for the target signal were increased in the presence of masking in different temporal target signal positions. Only pitch differed between the two groups. There were differences between the genders regarding frequency, shimmer, the overall severity of the alteration, and roughness. There was a correlation regarding temporal resolution ability and the overall severity of the alteration and roughness of the voice. Conclusion There is a central auditory impairment in temporal resolution which is correlated with vocal alterations in the elderly.
