Immediate Effect of Semioccluded Vocal Tract Exercises Using Resonance Tube Phonation in Water on Women Without Vocal Complaints.

Objective: To analyze the immediate effects of semioccluded vocal tract exercises on vocal quality and vocal self-assessment using resonance tube phonation in water in women without voice complaints, and to compare these results with those obtained using tongue trills and unvoiced fricative exercises.

Methods: This was a quasi-experimental study. The participants were 30 women aged 18-39 years and without vocal complaints.

Pitch-Matching Accuracy and Temporal Auditory Processing.

 Pitch-matching refers to the ability to vocally reproduce an acoustic model in a corresponding tone to the presented sound. This ability, which is dependent on pitch perception ability, can vary among individuals, and some are not able to sing in the correct tune or discriminate differences between tones.  To correlate pitch-matching accuracy and auditory processing in individuals without musical training.

Immediate effects of the semi-occluded vocal tract exercise with LaxVox® tube in singers.

Purpose: The purpose of this study was to analyze the immediate effects of the semi-occluded vocal tract exercise (SOVTE) using the LaxVox® tube in singers.

Methods: Participants were 23 singers, classical singing students, aged 18 to 47 years (mean age = 27.2 years).

Acoustic characteristics of the metallic voice quality.

Purpose: To characterize the fundamental frequency and the frequency of the formants F1, F2, F3, and F4 from vocal emissions of amateur singers with metallic voice quality.

Methods: There were 60 amateur female singers aged between 18 and 60 years old; 30 women with metallic voice quality forming the study group (SG) and 30 women without such a vocal quality forming control group (CG). The sample was selected through voice screening confirmed by reviewers after reaching a consensus.
