The main objective of this paper is to emphasize the importance of caring for and preservation of the voice of kindergarten teachers because they are first speech role models for children. Throughout the theoretical part of the paper, a description of the speech and language development of a child from his birth to the sixth year of it’s life is given. Because the vocal hygiene of kindergarten teachers is of utmost importance, exercises for voice care and proper pronunciation are presented and explained. Throughout the research part of the paper, speech records of ten kindergarten teachers were analyzed. Phonation, fundamental frequencies, wave forms of vocal cord vibrations (shimmer and jitter), harmonics to noise ratio (HNR), intensity, system of pronunciation, assimilations and expressive reading of a passage of a picture book were examined. The results show chronic hoarseness of kindergarten teacher and a poor quality noisy voice. The examination of the accent pronunciation system showed the predominance of the percussive accent system. The examination of speech assimilations showed tendency of hypercorrect pronunciation and non-implementation of certain types of assimilations. While reading the picture book, kindergarten teachers showed a high level of expressiveness and skill using prosodic features.
