The aim of this study was to rank vocal exercises using semi-occluded vocal tracts (SOVT) as a function of their effect on subglottal pressure (SGP) and on transglottal pressure (TGP). Direct measurements were performed in two healthy females. The correct realization of vocal exercises was controlled by maintaining a constant airflow at the phonation onset. TGP varied from 1.8 to 5.9 hPa among SOVT, in the same range as phonation threshold pressure values. SGP varied among subjects from 19.4…

Duration of biodynamic changes associated with water resistance therapy
TLDR
WRT showed strong inter-individual effects concerning the changes in the evaluated measures post-intervention, and general tendencies of some measures directly after the intervention showed a brief effect of only a few minutes.

Vocal and self-perception effects of straw phonation exercises
ABSTRACT Purpose: to assess the acoustic and self-perceived voice changes in women with and without voice symptoms after 1, 3, 5, and 7 minutes of straw phonation exercises. Methods: a total of 30
Dosage dependent effect of high-resistance straw exercise in dysphonic and non-dysphonic women.
TLDR
Positive vocal changes were observed with the high-resistance straw exercise; however, there are dosage restrictions, especially for dysphonic women.
Effects of a simulated system of straw phonation on the complete phonatory range of excised canine larynges
TLDR
The improved phonatory range demonstrated that straw phonation had the potential to prevent voice users who have high voice demand from voice fatigue and vocal damage, indicating a better voice economy and voice control.

TLDR
The combination of epilaryngeal airway narrowing and lengthening, a pharyngeAL expansion, and an oral narrowing behind the tube produce the best overall inertagram for pitch glide exercises.

TLDR
Investigating the underlying physical principles behind the training and therapy approaches that use semi-occluded vocal tract shapes found that therapy approaches are designed to match the glottal impedance to the input impedance of the vocal tract.
Direct measurement of onset and offset phonation threshold pressure in normal subjects.
TLDR
Univariate analysis showed that phonation threshold pressure was influenced most strongly by fundamental frequency and intensity, and multiple linear regression showed that these two variables, as well as laryngeal airway resistance, most strongly predicted phonation thresholds pressure.

Glottal open quotient in singing: measurements and correlation with laryngeal mechanisms, vocal intensity, and fundamental frequency.
TLDR
The results show that open quotient depends on the laryngeal mechanisms, and is strongly related to vocal intensity in mechanism 1 and to fundamental frequency in mechanism 2.

Effects on vocal fold collision and phonation threshold pressure of resonance tube phonation with tube end in water.
TLDR
Resonance tube phonation significantly raised CTP and tended to improve perceptual ratings of voice quality, which was mostly greater in singers who did not practice singing daily and in singers rated as being less experienced.
Initial validation of an indirect measure of subglottal pressure during vowels.
TLDR
This indirect method for measuring subglottal pressure from records of oral pressure during consonants, proposed and applied to studies of glottal resistance during phonation, appears to provide valid results.
Objective Voice Analysis in Dysphonic Patients: New Data Including Nonlinear Measurements
TLDR
A comparative study of objective voice evaluation using a multiparametric protocol including aerodynamic parameters and linear and nonlinear acoustic parameters recorded on an EVA® workstation and perceptual voice analysis by a jury found a nonlinear combination of only 7 parameters allowed classification of 81% voice samples in the same grade as the jury in women and 84% in men.
