The diploma thesis deals with the approach to work with breath and voice according to Ivana Vostárková. The aim of the diploma thesis is to analyze the experience of participants who went through a voice seminar with Ivana Vostárková and the subsequent anchoring of the statement in the field of social pedagogy. The theoretical part of the work is carried out in the spirit of personal development, through topics that grew out of research interviews. It deals with concepts such as personality, voice, breath, game, imagination and emotions. These are further discussed in the context of areas of social pedagogy, such as experiential pedagogy and psychotherapy. In the research part of the work, in-depth interviews with three participants of Ivana Vostárková's voice seminar are processed using interpretive phenomenological analysis.
