I am going to present the results of the research into the influence of
stress on the vocal organ of a teacher. Over 200 people participated in the research, 100 of
them being teachers and the rest constituting a control group. All of them completed the Voice
Handicap Index test (measuring the handicap level of the voice) as well as the PSS10 test
(measuring the level of the stress being felt); in addition, they took part in a professional
research into vocal emission where particular spheres of their voice were evaluated (motorics
of the articulatory apparatus, the way resonators work, the breathing track, speech quality,
vocal fatigue level etc.); also, they went through spirometer checkups. The results of the
research show which parameters are dependent the most on the level of stress felt at a
particular moment in time. What is more, thanks to the analysis of the results in the study and
control groups, it was possible to answer the question whether the obtained relations are
specific only to teachers as a group.
