Pure helium is a medium that allows sound to pass through it more quickly than air, so it makes your voice sound higher pitched (the mechanics are similar to speeding up a video and hearing the sound pitch up). Some gases will do the opposite; most commonly, sulfur hexaflouride, which slows down sound waves.
Assuming all of the gases are pure, and they replace the oxygen you would die instantly at Hydrogen, due to asphyxiation. Thatâs no fun, so letâs imagine âenoughâ of each gas is added for there to be an effect, but there is still oxygen to breathe. Hydrogen-Squeaky voice, no effect.
