Executives' speech expressiveness: analysis of perceptive and acoustic aspects of vocal dynamics.

Purpose: To analyze speech expressiveness in a group of executives based on perceptive and acoustic aspects of vocal dynamics.

Methods: Four male subjects participated in the research study (S1, S2, S3, and S4). The assessments included the Kingdomality test to obtain the keywords of communicative attitudes; perceptive-auditory assessment to characterize vocal quality and dynamics, performed by three judges who are speech language pathologists; perceptiveauditory assessment to judge the chosen keywords; speech acoustics to assess prosodic elements (Praat software); and a statistical analysis.
