All the time radio and television waves are leaving earth and traveling through space. so if you are talking on the radio or the television then your speech will travel through space at the speed of light and just keep on going.

Because physicists say that one cannot destroy energy, and the sounds that are created are a form of energy, then one might assume that the energy continues out through the universe forever.
However, as sound is created, there is a fixed amount of energy in the "sound byte" created. That energy spreads out in a bubble around the speaker. As waves of that energy hits solids, it is transformed into heat, etc. and is no longer in sound format. This means that, over time, the sound byte energy is gradually absorbed, by bodies, clouds, buildings, grass, carpet, pets, airplanes, planets, moods, stars, space dust, etc.
In theory, I suppose tinier and tinier bits of the energy might be going on "forever", but in micro-seconds the amount of energy remaining is so small that it becomes less and less likely to be heard.

confident. potential can't be created or destroyed. as quickly as you communicate, the sound waves will surely deplete. however the potential that the sound wave misplaced, became picked up via something else, and the "something else" that picked up the potential will ultimately provide up the potential to something else, and that something else will take the potential use it for yet yet another factor, etc etc, perpetually. The potential has to pass someplace, it could't be destroyed, it could no longer in straightforward terms dissappear magically. there's a by no skill ending pass of potential, kinetic to thermal, chemical or electric powered and to others that we'd understand exist. The potential could be saved for a collectively as or could be lively, even though it could certainly no longer in straightforward terms "pass away" the universe. The universe is a extensive closed gadget. the actual difficult question is... the place the potential got here from that enable you to communicate.

space is in a vacuum. therefore there is nothing for the sound to travel through. no sound in "empty space"

OMG! You must have met the girl in my office who thinks her voice is meant for all ears!
