I made something that might work...
(please note that Freesound now has problems with moderating new sounds so it might be unavailable for a long time)
Whoah, great atmosphere!
In case you also want to add some effects to your voice for added drama, a very fun and quick solution might be the X-Orcism free VST plugin (registration required).
