Comparison of Supraglottic Activity and Spectral Slope Between Theater Actors and Vocally Untrained Subjects.

Purpose: The present study aimed to assess supraglottic activity in theater actors and to observe whether they present differences compared with subjects with no voice training. Acoustic and perceptual analyses were also performed.

Methods: A total of 20 participants were divided into two groups: an experimental group of trained theater actors, and a comparative group of subjects with no voice training.

How do laryngeal and respiratory functions contribute to differentiate actors/actresses and untrained voices?

Purpose: The present study aimed to compare actors/actresses's voices and vocally trained subjects through aerodynamic and electroglottographic (EGG) analyses. We hypothesized that glottal and breathing functions would reflect technical and physiological differences between vocally trained and untrained subjects.

Methods: Forty participants with normal voices participated in this study (20 professional theater actors and 20 untrained participants).

Laryngoscopic and spectral analysis of laryngeal and pharyngeal configuration in non-classical singing styles.

Purpose: The present study aimed to assess three different singing styles (pop, rock, and jazz) with laryngoscopic, acoustic, and perceptual analysis in healthy singers at different loudness levels. Special emphasis was given to the degree of anterior-posterior (A-P) laryngeal compression, medial laryngeal compression, vertical laryngeal position (VLP), and pharyngeal compression.

Study Design: Prospective study.
