ok most of the information I listed in previous comments came from this book:

some quotes:
"In 1975 Marjorie Swacker did an experimental study in which men and women were given a line drawing of a room to examine, and were then asked to describe the picture from memory...men talked overwhelming longer than women, on occasion having to be stopped by the experimenter as the tape ran out." (115)
"Deborah James and Janice Drakich (1993) found that out of 56 studies of adult mixed-gender interactions, 34 (61%) showed meales talking more than females overall, while only 2 studies showed females talking more overal. The remaining 20 studies showed either no gender differences (16) or sometimes males and sometimes females talking more (4)." (115)
"Joan Swann and David Graddol (1988) examined videotape of an extended discussion in two elementary school classrooms. In both cases, they found boys speaking almost twice as much as girls--in both number of turns and total number of words." (117)
More research I found:
Research found that men talk more often (Eakins and Eakins): men's turns 10.66 secs, women's 3-10
secs at faculty meetings.
At academic confernces (Swacker): women 40.7% of the presentations, 40% of audience. But only 27.2% asked questions.
"It's well documented that women tend to be interrupted more than men, and that women who interrupt others are seen more negatively than men who do" .-Deborah Tannen is a professor of linguistics at Georgetown and a 2012-13 fellow at the Center for Advanced Study in the Behavioral Sciences at Stanford.
