No, our bodies would not be able to produce sounds like talking if there was no air or any other medium around us. Sound requires a medium, such as air, water, or solids, to propagate and transmit vibrations.
When we speak, for example, our vocal cords vibrate, and these vibrations create sound waves that travel through the air. The sound waves then reach the listener's ears, and the auditory system processes them as speech or other sounds. Similarly, when we move or make physical contact with objects, the vibrations generated propagate through the surrounding medium, creating sound waves that can be heard.
In the absence of a medium like air, there would be no molecules or particles for the vibrations to travel through, and therefore, sound waves could not be transmitted. As a result, our vocalizations, movements, and other actions would not produce any audible sound.
It's worth noting that in different environments, such as in outer space or underwater, where the medium may be different from air, sound waves behave differently, and the ability to produce and perceive sound can be affected.
