Actually, gases' buoyancy affects the sound of your voice. Oxygen and nitrogen - the main components of our atmosphere - have a specific density that our vocal cords are accustomed to. If we breathed in an atmosphere with a different composition or density, assuming it was breathable and non-toxic, it could indeed change the sound of our voice. This doesn't mean oxygen specifically makes our voice deeper, but rather that we've evolved to use the mix of gases in our atmosphere efficiently for speech.

As a singer, this is super fascinating. I'm aware breathing helium does the high-pitch thing, but never considered our regular air could be altering our voice too. Makes me wonder how different gasses would affect my vocal performances. I’m not about to try it, but it’s interesting to think about.

Man, this is the content I come here for. Weird but kinda makes sense in a strange way. Think astronauts have to deal with this? Like their voices in the space station or moon landings. Gotta check out some of those recordings later.

Lol, that's the dumbest thing I've heard. We'd all be dead on Mars because, no oxygen? Plus the pressure's all wrong. Our voices are deeper because we've evolved with this mix of air. Go read a book or something.

Whoa, had no idea this was a thing. Does that mean each planet has its own 'voice'? What would Jupiter sound like? If only we could test this out, it would be so cool!

While the idea is amusing, it's important to note that our voice pitch changes with different gases due to their density and speed of sound. Helium is less dense than air, hence the higher pitch. Oxygen wouldn't inherently make our voices deeper; it's the balance of O2 and nitrogen we're used to. On Mars, without the proper mix of gases, you'd have a lot more to worry about than sounding like a chipmunk! Breathing there isn't an option without a spacesuit or a habitat dome with a controlled atmosphere.

Haha, that's hilarious to imagine! But seriously, different gases do affect your voice cuz of their density n stuff. So who knows, Martian air could totally make us sound funny if it wasn't, ya know, unbreathable. Sci-fi movies, GET ON THIS!

Dude, that's a trip. Never even thought about it that way. But like, if you've never tried sucking on a xenon balloon, it's the opposite of helium. Makes you sound like you're in slow motion. Maybe oxygen is just middle ground? Mind = blown.
