[Effect of voice emission training on the improvement in voice organ function among students attending the college of teachers]. / Ocena wplywu cwiczen, techniki emisji glosu na stan narzadu glosu u uczniów kolegium nauczycielskiego.

One of the major causes of frequent voice disorders in teachers is incorrect vocal emission technique. The aim of the study was to assess the effect of logopedic training on voice emission parameters and vocal organ disorders in students attending the college for teachers. The study group comprised 45 female students who experienced vocal abnormalities after excessive vocal effort. Questionnaire surveys, phoniatric and videostroboscopic examinations were performed in all subjects before starting and after completing the logopedic training. The training was preceded by a theoretical seminar on voice organ anatomy, physiology, and hygiene. The logopedic training lasting two-three months contributed to the improvement in voice characteristics and the condition of voice organ in the majority of students, as well as in phoniatric parameters, including the increase in the maximum phonation time, the frequency range of voice, the reduction of the glottal insufficiency and the elimination of "soft" vocal nodules. The results of the study indicate that the implemented voice emission training improved significantly voice quality and allowed for providing an efficient therapy of already existing functional disorders of the larynx.
