Vocal and facial expressions and meaning effects in speech expressivity

Abstract

The objective of this work is to investigate the congruence between non-verbal and verbal cues in persuasive speech. The selected corpus comprises video excerpts in which artists from divergent political perspectives provide support to the minister of the Brazilian Supreme Federal Court. The research methodology comprises: annotation of the video excerpts; text analysis; automatic analysis of the speakers' facial expressions and emotions by means of the FaceReader; analysis of the vocal quality and prosodic settings by means of the VPA; acoustic analysis of the data by means of the ExpressionEvaluator (Barbosa, 2009); and multivariate statistical analysis, applying MFA in R, package FactorMinerR, to correlate qualitative and quantitative variables. Results indicate the interplay among facial and vocal prosodies and intended persuasiveness.

Assessment of the Psychophysiological State of Female Operators Under Simulated Microgravity

“…Simultaneously with the audio recording of DPC audio messages, for the first time, within the framework of the experiment in the conditions of "dry" immersion, video recording was included to our experimental protocol for the analysis of basic emotions using facial expressions (Sanchez et al, 2014). Within the united methodical approach, acoustic analysis of speech and analysis of facial expressions can become promising means of remote monitoring of the psychoemotional and psychophysiological state of human operator both in space flight and in other extreme conditions (Fontes and Madureira, 2019;Gushchin et al, 2020).…”
