We agree with Tannen that the circumstances of increased talking represent a significant gender difference in public speaking: Women speak more in personal situations, men more in public venues. As Tannen summarizes: "Studies that find men talking more are usually carried out in formal experiments or public contexts such as meetings." Her article notes studies in which there's:
When do you tend to talk, and when do you tend to remain silent? What do you use your speaking opportunities to do: report or build rapport? It's a good speech-preparation exercise and something you may want to journal about or discuss with a trusted advisor, to make yourself aware of your choices when speaking opportunities arise.
....an overall pattern of men speaking more. That's a conclusion women often come to when men hold forth at meetings, in social groups or when delivering one-on-one lectures. All of us -- women and men -- tend to notice others talking more in situations where we talk less.
Counting may be a start -- or a stop along the way -- to understanding gender differences. But it's understanding when we tend to talk and what we're doing with words that yields insights we can count on.
