This research examines how vocal tones impact persuasion in an online appeal. It supports the hypotheses that appeals are more successful when persuaders’ vocal tones as reflected with LVA parameters show greater focus, less stress, and less extreme emotion. With two controlled experiments, the researchers then replicated their findings that vocal tone impacts funding decisions and also show that perceived competence mediates the relationship between vocal tone and persuasion attempt success. Research introduces audio mining to the marketing literature and speaks to the value of combining secondary data and experiments when investigating persuasion.

ABSTRACT: We examine whether vocal markers of cognitive dissonance are useful for detecting financial misreporting. We use speech samples of CEOs during earnings conference calls, and generate vocal dissonance markers using automated vocal emotion analysis software. We begin by assessing construct validity for the software-generated dissonance markers by correlating them with four dissonance-from-misreporting proxies obtained in a laboratory setting. We find a positive association between these proxies and vocal dissonance markers generated by the software, suggesting the software’s dissonance markers have construct validity…

Research by Mamata Medical College correlating 16PF personality test with LVA emotional readings.
ABSTRACT: “Introduction Voice opens a door through which emotions fleetly escape analogous to actions manifesting one’s personality traits. Voice analysis is the study of speech sounds for purposes other than linguistic content, such as in speech recognition. Layered voice analysis identifies various types of stress levels, cognitive processes, and emotional reactions that are reflected in different properties of the voice.
