Its not much but starting at 1:49, Samus for the first time in history speaks her first words. And yes its very sexy.
Her verbal Taunts include:
"Try Me" Swings her whip around, full circle
"Is that all" Throws her pistol into the air
"MMmmmm" Does a 720 degree spin with the whip twirling around her
EDIT:
The link might not take you to the video properly so heres what to do. Hit Brawl, in the featured section below the video screen then hit taunts on the left.
Or use this youtube link, curtosy of sc94797 (thanks by the way):
