The purpose of the present study was to investigate the vocal tract and glottal function during and after phonation into a glass tube and a stirring straw. Acoustic results showed a stronger spectral prominence in the singer/speaker’s formant cluster region after tube and straw phonation. Listening test demonstrated better voice quality after exercising than before. EGG contact quotient decreased during both tube and subglottic pressure became higher. One of the major changes was the more prominent singer’s/speaker’s formant cluster. Vocal tract and glottal modifications were more prominent during and after straw exercising compared to tube phonation.
