The author discusses vocalizations as using non-verbal voice sounds in self-expression and self-inquiry. The purpose of the study was to investigate the experience of self-expression and self-inquiry through vocalizations in the situations of valuing and evaluating. The researcher hypothesized that placing an individual in a safe place for self-expression on the conditions of valuing creates more authentic and genuine feelings, helping to reveal their authentic voice. On the contrary, placing a person under conditions of evaluating and impressiveness leads to a less authentic feeling and sounding. Two groups of participants were separated. The expressive group was created using the condition of valuing. The impressive group was created using the condition of evaluating. Participants in both groups used their voices to express themselves performing research tasks and then filled out the survey applications reflecting the sounder’s body, voice, feelings and listener’s feelings during the research. The application’s indicators were grouped into six factors: “Psychophysiological authenticity”, “Psychological authenticity”, “Satisfaction”, “Vocalization change”, “Perceived emotional involvement”, and “Perceived satisfaction”. The multilinear mixed effect regression models were built to investigate the influence of the research conditions on these factors and their dynamics. The t-test was used to compare the results between the groups. Significant differences were revealed with the factors “Psychophysiological authenticity”, “Psychological authenticity”, “Satisfaction”, and “Perceived satisfaction”. They were greater in the expressive group than they were in the impressive group. The indicators of “Perceived satisfaction” were growing.
