In a study of more than 155,000 company conference calls over the past 19 years, Prattle found that men spoke 92 percent of the time. That's partly because male executives and analysts far outnumber women in those roles. It's also because men just talk more. "Male executives provide significantly more verbose answers to analyst questions than their female counterparts," Prattle CEO Evan Schnidman said. "One could surmise that male executives are more prone to speaking simply to hear themselves speak."
