Testing your vocal cords on another planet is a deadly experiment. If you were to voyage to another planet, step out of your spaceship and remove your helmet in order to announce your arrival, you’d be dead within minutes… or even seconds. However, if you were able to speak on other planets and moons throughout the Solar System, the varied atmospheres and surface conditions would affect your vocal cords in a different way than on Earth, making you sound like a different person.
Your ability to speak is possible because of airflow vibrating against the larynx, producing sound waves that then propagate through the atmosphere, which are then carried to, and received by, the eardrums. But what happens if the atmosphere, the medium for voice vibrations, and the surface conditions are tweaked somewhat?
