CO2 is used for fizz because it dissolves in water extremely well and mostly safe. Speed of sound in CO2 is almost 20% lower than air's, if would be noticeable if it worked.

Having gas in your stomach will only change the tone of your burps. When talking, the voice box and resonating cavities almost immediately filled with gas from the lungs, replacing what was there.

Tl;dr: not possible, foreign gas needs to be in the lungs to affect tone of voice.

Also because it reacts with water to form carbon acid which affects the taste of beverages

Not in a good way though.

"Soda" is called that because most carbonated bevs contain baking soda to compensate.

There is one common drink (seltzer?) that does not have soda.

Ah, so that's why seltzer tastes, uhh, like seltzer despite being similar in appearance to sodas.

Soft drinks don’t contain sodium bicarbonate.

That was used in the old days to make soda water, and thus became the colloquial name for all carbonated beverages when soft drinks became popular. But CO2 is added directly to modern sodas, no bicarbonate reaction required.

Check out sodium content on a coca-cola can, then try attributing it to one of the ingredients below.

Sodium comes from many additives, including from salt directly which is common to counter balance the sweetness. Baking soda is not some hidden ingredient and would actually just react with the acids they put in for the taste.

Ok, I buy. Which listed additives would you suspect for sodium?

Coca cola label: https://us.coca-cola.com/products/coca-cola/original

Anything ionic will likely have a sodium ion. That includes the coloring and natural flavors. Keep in mind that there is only 0.01% sodium by weight according to that label, even the smallest additives can easily account for that.

Yes the only way the gas gets into your lungs is if you let the liquid sit in your mouth while you inhale. This is a great way to choke on the liquid, and will barely get any gas into your lungs anyway.

Good point. One can transfer gas into lungs by burp-inhaling (don't recommend).

In that case, methane dissolves in cold water very well, forming hydrate ice. BP's Deep Horizon oil platform felt the power of hydrates seconds before exploding.

So what you're saying is that I need to breathe my Coke instead of drinking it?

Adventure!!!

Coke is seriously acidic, pulmonary edema can kill the adventure (and the adventurer).

Imagine inhaling lemon juice.

Ok so what if you carbonate the drink with a heavier/lighter gas and then it goes down the wrong hole, would your gurgles for help be high-pitched?

Quick note - it is not the speed of sound in the gas that affects a person's voice, it is the density of the gas that affects resonance. Speed of sound usually correlates with gas density if the pressure remains equal, however, so it is easy to conflate the cause there.

Gas density will also affect how Bernoulli's principle causes your vocal cords to vibrate - a less dense gas will lessen the effect of Bernoulli's principle, which is responsible for pulling your vocal cords into the moving airstream - but this is counterbalanced by the fact that it also offers less physical resistance to your cords springing back and forth, and that it requires less effort for your diaphragm and lungs to expel. The result is that more gas volume will be expelled for a given amount of effort i.e. your lungs will push out the air faster if you do not consciously compensate, thereby increasing the effect of Bernoulli's principle. So these two effects more or less cancel out and the fundamental pitch and amplitude of a person's voice will remain basically consistent.

Rather, it is the resonant characteristics of your head and chest, which give your voice its unique timbre, and distinguish it from another person's voice (and indeed from a piano or violin), which will be noticeably affected.

Air density is lower by half (at least) at mount Everest. I don't remember mountain climbers having funny voices at altitude.

Are you sure about your density statement?

I was going to say though, I could swear my voice gets slightly deeper immediately after a burp after chugging a coke.

The helium goes into your lungs while a beverage goes into your stomach. You might be able to affect a change in the pitch of your burps.

As an experiment you could drink some nitro pepsi or guiness nitro ipa, record the ensuing belching and play it in to a spectrum analyzer to quantify the belch pitch change.

Not going to work.

Air is already 80% nitrogen gas and ~20% oxygen. You won't get any appreciable change in the gas composition by inputting more nitrogen.

It might be different, the two main things we belch are co2 from carbonated beverages or gasses released by gut bacteria metabolisms

You can use different gases (see Pepsis new nitrogen based fizzy drink) to infuse a drink. Helium and other gases may not dissolve as well though. You need to induce a good sum of pressure to dissolve the gas into the liquid and the amount of gas dissolved is fairly high to achieve the “carbonated,” effect when you open the beverage. Not all gases will be able to achieve that or the pressure may be so high to keep those gases in the drink a conventional beverage becomes impractical as storage (the actual cans) becomes a larger factor.

Secondly the gas changing your voice; you’d need to be directly inhaling the gas for it to reach your vocal chords and the important vocalization structures in your larynx. Your epiglottis closes off all air/liquid passage to the larynx and lungs when you drink a beverage so the gas would be largely impassable; unless you directly breathed the gas in from the drink (this would still likely not produce enough gas to change your voice; you’re better off just inhaling the gas at this point due to cost and effectiveness).
