It is a good question:
   Are we the voice of the Universe?
   At present, yes we are.
   Aliens found: 0
   Animals found: Many
   Humans found: Not as many.
   Number of animals humans can talk to that aren't human to
   compare their thoughts on the Universe with: 0

   So, yeah, at present, we're it.

   The only voice of the Universe provably is human.
