Description
Summary:To verify the auditory-perceptual and acoustic effects of the semioccluded vocal tract exercise with Finnish tube on the vocal quality of a deaf musician. A seven-day protocol with Finnish tube was performed with guidance for its home replication twice a day. A 46-years-old man with profound bilateral sensorineural hearing loss, musician and composer participated. Before and after the application of the protocol had undergone tonal audiometry, nasofibrolaryngoscopy, acoustic analysis with Praat and auditory-perceptual evaluation of the voice with Voice Profile Analysis Scheme for Brazilian Portuguese. The postintervention auditory-perceptual analysis identified reduction of the deviation in lip spreading, extensive labial range, raised tongue body, pharyngeal expansion, nasal resonance, larynx height, larynx and vocal tract tension and irregularity, pitch, speech rate, and a better respiratory support. The maximum phonation time reduced, probably because of elimination of the abrupt vocal attack and tension, articulatory deviations, improvement in voicing and the absence of the use of expiratory reserve air. The fundamental frequency became lower, and the first, second, third, and fourth formants became higher. The jitter increased, and the shimmer reduced. The use of the Finnish tube might have facilitated the voicing sensations in the deaf musician, by enhancing the tactile-kinesthetic perception of the vocal tract and brought a greater source-filter interaction.
