Voice is just sound. Sound does not remain forever.

Things spoken create sound waves. Below is a definition of sound waves from Wikepedia. It explains that sound travels giving off energy. eventually there is no more energy so the sound dies away.
"Noise and sound often mean the same thing; they differ when a noise is an unwanted sound. In science and engineering, noise is an undesirable component that obscures a signal.
Humans perceive sound by the sense of hearing. By sound, we commonly mean the vibrations that travel through air and can be heard by humans. However, scientists and engineers use a wider definition of sound that includes low and high frequency vibrations in air that cannot be heard by humans, and vibrations that travel through all forms of matter, gases, liquids and solids. The matter that supports the sound is called the medium. Sound propagates as waves of alternating pressure, causing local regions of compression and rarefaction. Particles in the medium are displaced by the wave and oscillate. The scientific study of sound is called acoustics.
Sound can be characterized as a disturbance of molecules across one of the three types of mediums listed above. As the wave passes across the medium it transfers its energy along the molecules by particle interaction. Since it always needs a medium through which to travel, in environments that resemble a vacuum, such as outer space, there cannot be any audible sound."

well, when you say something, your products are sound waves (from your words) and carbon dioxide. even if those sound waves stop echoing in the atmosphere, which is bound to happen, those words may linger in the memories of the people around you and your CO2 goes back into the atmosphere and to be used by plants in the process of photo synthesis and their products are food and oxygen to be breathed again by people and to be released when we exhale and talk and bacuase the cycle repeats itself and your CO2 is technically still in the atmosphere but can be in a different form, I'd have to say yes because it remains in the atmosphere to be recycled forever from CO2 to O2 back to CO2 and it just goes on... *gasp* inhale... exhale... wow that was a mouthful.... >_>

voice destroyed just after few seconds in the form we feel it but voice is energy of wave and when wave is interact with anything it just transmit its energy to some other form and that in some other.now you have to think is it destroyed or not

in an echo it repeats but eventully it stops when there is a sound barrier. Is that what you mean?
