Abstract
ABSTRACT Purpose: to compare the results of maximum phonation times (MPTs) under two different forms of speech-language pathology orientation to extract these measures. Methods: 60 women between 17 and 23 years divided equally into two groups participated: Study Group (SG) - that performed the task under the two forms of orientation (traditional orientation and with control request of the air outlet); and the Control Group (CG) - which carried out the task in a single form of orientation (traditional one). The procedures performed comprised the extraction of MPT in the vowels /a/, /i/ and /u/, the fricatives /s/ and /z/ and numbers counting. The data were tabulated and statistically analyzed (p<0.05). Results: by comparing the two groups at the first instant of the MPT emissions, no statistically significant differences were found. However, when the second instant was compared, there were differences in most emissions, which indicates that the air control request promotes the increase of MPTs. Conclusion: the way the speech-language pathologist guides the performance of the maximum phonation times, during the evaluation of these measures, requesting the individual tomaximally control air exit, modifies the result of the extraction of the temporal measures of the voice, which must be considered in the daily vocal clinical practice.
Highlights
Vocal disturbances are understood as deviations that change voice intelligibility and effectiveness, and they can be manifested in several ways, such as changes in the vocal intensity, frequency and quality
Subjects were 60 women aged between 17 and 23 years who were divided into two groups: Study Group (SG) - who performed the task under two forms of speechlanguage pathology guidance; and Control Group (CG) - who performed the task under a single form of speech-language pathology guidance twice
For all the collected samples, the results showed that there are differences between the maximum phonation times (MPTs) obtained in the two ways of guidance given to the SG
Summary
Vocal disturbances are understood as deviations that change voice intelligibility and effectiveness, and they can be manifested in several ways, such as changes in the vocal intensity, frequency and quality. The objective of voice speech assessment is to understand, describe and identify the subject’s vocal behavior, identify the causal factor of a possible dysphonia, and describe the observed voice characteristics. Such evaluation consists of several procedures such as anamnesis, auditory-perceptual evaluation, acoustical analysis and self-assessment[2]
