When we talk air passes out from our lungs through our vocal chords and is caused to vibrate and you hear the words. When you mix helium with air the resulting mix is less dense so as you breathe out the timbre of your voice is altered. The speed of sound in a less dense helium/air mix is higher than in just air. You are increasing the speed of sound of your voice when breathing out this less dense mixture and this increase in speed will affect the frequencies that make up your 'voice'.
If the frequencies are affected the timbre is affected too. A more dense gas may have a very weird affect.
Strictly speaking although most people say it is the pitch that changes, it is the actually the 'timbre' which is changed, as your vocal chords produce the same shapes and therefore the same pitch.

No, he isn't. the reason being as a results of the fact the fee of sound in helium is a few distance swifter, because of the fact helium is thinner than air. This reasons the pitch of you vocal cords' resonant frequency to strengthen, and sound greater. you could decrease the pitch by potential of respiration in a extra dense gas as nicely.

It isn't the inhale, it's the exhale. Lighter than air,helium makes them vibrate faster and you sound silly. Remember on Johnny Carson? LOL

Nothing it has something to do with the air density of helium versus normal air that is why your voice changes

Nothing, as stated before, it is the result of the change in te density of gas. The same effect happens in a hyperbaric chamber. (Also called a decompression or recompression chamber.)

it is an inert gas hence nothing happens to your vocal chords

idk but it makes you sound cool. i dont suppose its good for you cuz afterwards i have some trouble breathing. also-if you buy a can of it, the box says not to inhale it. if you want to breathe it in, just know there are risks.

I suspect they tighten causing your voice to be high pitched when you speak.
