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.
It can damage your voice. Because men usually want a deeper voice than the one they have, theyâll artificially lower it by projecting their voice from the lower part of their throat. To hear and feel what I mean, speak in the lowest pitch that you can, and pay attention to where you feel the sound emanating.
