A Study on the Influence of Paralanguage and Non-verbal Messages in Persuasive Speeches - Focused on Obama's Speeches

Communication emerges as the quintessential bedrock of existence, pivotal in steering the course of our lives through the adeptness and proficiency with which we partake in this elemental activity. It encapsulates the quintessence of discourse, relationships, and the very essence of life, laying the groundwork upon which the cosmos functions. The efficacy of persuasion hinges on a meticulous evaluation of both verbal and non-verbal cues, with the latter frequently being egregiously overlooked. The profound influence of paralanguage and non-verbal elements in the conveyance of messages has been thoroughly expounded upon, accentuating the critical role these non-verbal indicators play. According to Mehrabian’s principle, non-verbal cues and paralanguage constitute 93% of the communicative process during speeches, significantly influencing audience understanding and engagement, thereby proving to be indispensable for effective communication. Within the realm of modern discourse, the rhetorical finesse of Barack Obama, especially evidenced through his seminal appearance at the Democratic National Convention (DNC) in 2004 and his triumphant speech in 2008, illustrates how his masterful employment of paralanguage and non-verbal cues profoundly connected with the audience, en-gendering a profound sense of empathy. This paper not only highlights the power of skilled communication but also articulates the paramount significance of non-verbal elements in establishing rapport with the audience.
