Watch: Kim Kardashian takes no prisoners when it comes to Caitlyn's attempts at a 'feminine voice'

"YOU SOUND NO DIFFERENT" pretty much sums up Kim's review of Caitlyn Jenner's "best feminine voice." 

The snippet, which appears in an upcoming episode of I Am Cait, sees Caitlyn Jenner role play a call down to "room service" to see if whoever receiving the call would say "Yes, Ma'am."

The voice is the last bastion when transitioning. It's often the only tell tale sign of a previous incarnation, and that has to be extremely difficult to deal with at times.

Speaking on the matter after her conversation with Kim, Caitlyn said: "Women cannot relate to the whole voice thing. They don't see it as being that important when it is that important, not only for you to speak and order and do all that kind of stuff, but very important for your soul that you're feeling good about that."
