Here it is folks, from last weeks ‘Conan Obrien’ Show. We have Liv Tyler (Arwen) speaking elvish! Click on the link to listen (MP3 or Real Audio). [elvish_tyler.mp3] [elvish_tyler.ra]

What does she say? Well, Ringer Fran sends in this info:

‘Now my Lord, winter has not yet come. Would you before your time leave your people?’

Which I guess is spoken to Aragorn and taken from somewhere in the history of Arwen and Aragorn in the appendices.
