In the following video (The Secret Behind a CEO’s Success May Be in the Voice), Robert Lee Hotz talks about the link between voice and business success. He explains that researchers who have studied the speech patterns of successful business executives and leaders have found that their voices share a certain set of characteristics across different language and culture groups. They are able to both persuade and inspire trust in the audience when using the following vocal qualities:
- Abrupt increasing and decreasing vocal pitch
- Varied total range
- Sometime harsh high vocal frequencies
- Lower vocal pitch on words that end with vowels
Hotz admits that this information is based only on the study of men’s vocal qualities. Is it the same for women leaders and executives? How would you describe the voice of a charismatic female public speaker?
