The human voice is a powerful instrument of persuasion and leadership. It reflects the speaker’s personality, social status, emotions. Scientific studies have highlighted the link between vocal skills and the quality of professional communication. The way we speak determines how much people appreciate, respect and trust us. Also, all of the communication channels (facial expressions, gestures, posture, gaze) influence the perception of our credibility, our dynamism and our competence. This workshop will give you the opportunity to master the strategic use of voice and non-verbal channels in professional communication.
