i don't see what's odd about the second site. but maybe that's just me. anyway, the best translation i've ever seen is "Divine echo" - in other words, it's the echo of Revelation, not a new Revelation, simply an angelic voice repeating what has already been said on the subject for a new audience. batei qol are superior to some forms of authority and can be "used in the event of a tie", in theory, but they cannot overrule a majority interpretative decision of humans, (illustrated by the famous story of the oven of achnai in bava metzia 59b) nor do they outrank prophecy - prophecy had ceased by the time of the batei qol. now we do not even hear them.
