VOICE PITCH PECULIARITIES IN ELIZABETH HOLMES’ INTERVIEWS

Abstract

This article focuses on the study of voice pitch as one of the identifiers of deception and highlights the peculiarities of using a lowered tone on the example of an interview with Elizabeth Holmes. The analysis was carried out using the PRAAT program, or rather a scripting language known as Prosogram based on it. This script enables the analysis of voice wav files and presents the data in the visual form of a speaker profile. As a result of the analysis, a number of profiles demonstrate a tendency of inconsistency in the use of tone between different interviews and speeches. At the same time, the data also shows the opposite result within the same interview. In this case, the speaker maintains the pitch of his voice at the same level throughout the conversation with minimal fluctuations. In addition, the analysis also suggests that the speaker's behavior is not conditioned by the gender of the interlocutor and is caused by other social factors. For further research, we propose further analysis of speech behavior and comparison of the subject of study (in our case, Elizabeth Holmes) with contemporaries.
