The Power of an Actor’s Voice and Diction in Emotional Influence on the Audience

Abstract

Throughout the annals of theatrical history, the power of an actor’s voice and diction has served as the bedrock upon which emotional narratives are built, creating a profound impact on audiences that transcends the mere recitation of lines. The dynamic interplay between vocal expression and diction is an art form studied across disciplines such as neuroscience, psychology, linguistics, and performance studies, with modern research indicating that nuances in an actor’s vocal delivery — variations in pitch, tone, rhythm, and volume — can trigger specific neural responses associated with emotional processing and deepen audience engagement.
