I don't know this for a fact but is what I think happens is when you talk the sound wave's of you voice bounce off the cave, because it's so open and empty, and there's nothing for it to run into like chairs tables cars doors stuff like that,it's empty and hallow. That's what i think. go to Google or WikiPedia to find out for sure. :) Have a blessed Day!

It is a gas that weighs 6 pound. sulfurhexafluoride helium weighs -6 pounds. that's why when you inhale helium, your voice goes up. and when you inhale sulfur hexafluoride your voice is weighed down to a lower voice. it sounds awsome.

Yes, caves can create echoes due to the reverberation of sound waves off the walls and surfaces. The acoustics of a cave can amplify and prolong the sound, creating a noticeable echo effect.
