Abstract:

OBJECTIVE: To compare the magnitude of the symptoms of vocal fatigue in young women before and after two hours of continuous speech. MATERIAL AND METHOD: 20 young women, average age 20 years old, without vocal and laryngeal and that did not use professional voice. This study was approved by CEP-HCRP (# 9711/2008), performed at the Laboratory of Voice and Speech - HCFMRP in the morning, with the participants fasting and absolute voice rest for 8 hours. For proof of continuous speech, we used standard text for reading and repeating continuously for 2 hours in silent environment, and relative humidity and temperature monitored by thermo hygrometer. Before and after proof of continuous speech, participants were asked to mark on visual-analog scale - 100 mm ruler, whose ends were standardized as "minimal sensation" and "maximum sensation" - how they felt at that moment, each of the symptoms listed on a questionnaire. The analysis was performed using the nonparametric Wilcoxon test and the significance level (p) ≤ 0.05. RESULTS: The symptoms hoarseness, dry throat, breaks in the voice, sore throat, low pitch, vocal effort, weak voice, neck pain and tension, tiredness and need to talk to cough or clear his throat, showed a statistically significant difference comparing pre and post-test, demonstrating an increase in their magnitudes. CONCLUSION: Two hours of continuous speech were able to increase the symptoms of vocal fatigue in young women without vocal, reflecting an increase in phonatory effort and the dryness of the mucous, causing the need to cough and throat clearing.
