In speech, women are more prone to have a high-frequency "s", use uptalk (sound like they're asking a question when they're not), avoid swearing, and use words to exaggerate their feelings (like "extremely" hard, "pretty" good). I doubt all women are like this, but these are some stereotypes, and there's truth to those sometimes.
As for walking, women tend to walk with their feet closer together, almost in a straight line, while men tend to walk with them spread wider. Also, men tend to have a bounce to their step, whereas women tend to glide. I learned this stuff in animation courses
Again, not gonna be true for everybody.
I'm interested in hearing more about male mannerisms.
