Phonation into a tube is a widely used method for vocal training and therapy. In order to find out whether there is any change in the physical adjustment of the vocal folds, two volunteer subjects were examined with computed tomography (CT). Both produced vowel [a:] at comfortable pitch and loudness. Results showed considerable variability in the intra- and inter-individual vocal fold configuration but did not reveal any unified trends in vocal fold adjustment during and after the phonation into the tube. The data indicate that the changes of voice quality after tube phonation are more likely due to vocal tract adjustments rather than due to vocal fold adjustments.
