The thesis titled Vocal health of preschool educators is a scientific work with a methodological component. Voice disorders are commonly divided into organic and functional categories. The latter are most often caused by vocal misuse, frequent vocal fatigue, or long-term overloading of the vocal apparatus. Given that educators in preschools speak for extended periods in very unfavorable conditions that include high levels of noise, the aim of this work is to examine their vocal health and lifestyle habits. To identify vocal difficulties, the educators answered questions based on the Voice Handicap Index (Jacobson et al., 1997), which examined their vocal, work, and lifestyle habits. Considering the strain on the vocal apparatus and the challenging speaking conditions under which preschool educators work, the existence of certain voice disorders is to be expected. The methodological component of the work presented exercises for strengthening the voice, as well as guidelines for the care and protection of the voice. This planned research is submitted to the Ethics Committee of the Department of Phonetics at the Faculty of Humanities and Social Sciences, University of Zagreb.
