The Wall Street Journal examined a small study of ten female business leaders, including Facebook COO Sheryl Sandberg and Yahoo CEO Marissa Mayer. The study, which was based on a comparison with a 423-person database, found that the difference between highly successful women and their lower ranking peers lies in something called "vocal energy."
Carrie Goldberger, a research analyst with communications analysis firm Quantified Impressions, tells the Journal that an energetic voice seems authentic to listeners. "Energetic" voices, in this context, vary in loudness and intensity, conveying the speaker's passion and commitment.
Vocal energy might also be a factor for male leaders as well. Goldberger points out that President Obama speaks in a higher pitch than previous presidents, but he also has a high degree of vocal energy.
The good news for aspiring leaders, world or otherwise, is that vocal energy is completely within our control. Unlike pitch, which we're largely stuck with, the intensity and varying volume with which we speak is something we can work on.
