Introduction Vocal techniques have shown to be important strategies to improve, promote and rehabilitate vocal health.
Purpose Verify the immediate impact of vocal techniques on the improvement of acoustic and aerodynamic parameters, vocal deviation and self-assessment.
Methods Descriptive, observational, comparative study including 40 women without vocal complaints, age range 18–45 years, equally divided into four groups according to the technique applied. The participants underwent voice assessment before and after performing the vocal technique. Each technique was performed for 1min and participants were re-evaluated in order to measure the immediate effects of the techniques on the parameters evaluated. For the analysis of the variables, the non-parametric Wilcoxon test was used.
Results Among the techniques studied, the high-pitched sound proved more effective in improving the acoustic and perceptual parameters, although in the other techniques was noticed a tendency to improvement in the result, but without statistical significance. In the self-assessment, the techniques to increase the maximum phonation time by softening the emission were more accepted by participants than those related to phonation resistance, which require more effort to be performed.
Conclusion The high-pitched sound technique favored an improved performance of participants in all parameters evaluated, although the other techniques studied showed a tendency to improvement in the evaluation measures.
