Why does breathing in Helium gas make your voice sound weird???

Because sound waves can travel faster through helium than oxygen because helium is a noble gas. So when you talk through helium the sound moves faster making it sound higher in pitch. If performed incorrectly it could kill you!

well... i don't know what is wrong with me all of a sudden but it seems like since i got pregnant i have asthma or something and my through feels like my tubes are all puffy inside so when i laugh when i'm out of breath i sould like mutley on that old racing cartoon. there's like barely any noise coming out, it just sounds like wheezing.

stick your head in the freezer and take deep breaths!! the cold air should irratate your throat enough to loose your voice....Well the cold weather does it for me, so that should work??? Then scream alot like everyone else says...

Your voice sounds funny to you in a recording because you're usually listening to it from inside your own head.  What you hear on a recording is how other people hear you, so if you don't like it, go get a voice coach or something.

When the person speaks, the helium in his lungs go into his mouth and out of his mouth and into the immediate space in front of it.\n\nWhen you hear his voice, it will have gone through a substantial amount of helium before going through air :)

S'ok, for you to be like that, it's quite normal. Guys usually change their voices like, around, 14-17, and i'm just sorta like you (i'm 14, and my voice is still high). Relax. \n\nHowever, if it doesn't change, then you'll have to change your accent to make it more attractive. A cool and calm one would do....

Human ears are adapted to hearing via air not via water.  Also there are a couple transition boundaries that muffle and distort the sound.  The first being the surface of the water in the pool.  The second being the air bubble that is still in your outer ear.\n\nIf you remove this air bubble by inverting your head and shaking it side to side you can actually hear "better".  But the speakers voice will be very distorted from passing through the first transition boundary.\n\nMake sure that you exercise proper ear care after your swim to ensure that water does not stay in your outer ear and cause an infection.

If you're still going through puberty, then your voice may still be "cracking".\n\nIf you're past puberty, then try speaking from your diaphram.  If you project from your throat, then your voice will be weak.  Practice speaking while flexing your abs, as if you're pushing out your voice from your stomach.  Do it forcefully so that you're loud.  Once you master this, you can project a deeper voice without being excessively loud.\n\nHave you ever taken Karate?  If so, then it is just like the Kiai yell.\n\nAnd if you have a naturally high voice, then there's nothing wrong with that.  It doesn't mean you're gay or straight.

I'm not sure. Are you a man? If you are then don't worry about it but if you don't like it you could try talking in a deeper voice and maybe adjusting your crotch every few minutes. Picking your nose and farting would help also. If you are female then good for you and have a nice day!

The vocal cords are two bands or folds of mucuous covered, elastic muscle tissue. They are located side by side in the voice box (LARNNX) When we are silent, the cords remain open. This is the airway throught which we breathe. \nSound is created when air fro the lungs is pushed throught the closed vocal cords causing them to vibrate - faster for higer sounds and slower for lower pitched sounds.\n\nThe sound quality of the voice is the result of the vocal cords opening and closing smoothly. If air manages to pass throught your vocal cords when it's not supposed to, the voice will sound raspy, hoarse, lower or higher than usual. \nThere are several reasons why a person can lose their voice. The vocal cords are subject to infections (laryngitis), Irritations (repetive strain or use of unhealthy substances like tabacco and alcohol), trauma (a blow to the larynx) and tumours (nodules, polps and ulcers).

(m)\n\nWhat helium does change is the timbre of your voice. Timbre is what allows you to distinguish between the same note played at the same volume on two different instruments. Timbre also allows you to distinguish different elements of speech (such as vowel sounds) from each other. For this last reason, timbre is very important to interpreting speech. \n\nWhen you speak, air travels from your lungs up through the larynx on its way out of your mouth. In the larynx are a pair of vocal folds which meet to form a V-shaped slit. On its way through, the air hits the underside of your vocal folds causing them to vibrate. This vibration then excites air molecules in your vocal tract, setting up resonant frequencies that are interpreted by the ear. By manipulating your vocal tract (moving your tongue, lips, soft palate, etc.) you can create different resonant frequencies allowing you to make the many different sounds of coherent speech. \n\nEveryday speech is a combination of the vibration of your vocal folds (which influences the pitch) and the vibration of the air in your vocal tract (which influences the timbre). When you say "ee," your tongue, lips, etc., are in a different configuration than when you say "ooh." Each speech element has a specific pattern of frequencies, like a fingerprint. The resonant frequencies that make the "ee" sound are distinct from those that produce "ooh". These distinct patterns allow us to recognize an "ee" sound regardless of pitch--a soprano singing "ee" produces the same resonant frequencies as a baritone singing "ee."\n\nHelium is significantly less dense than air. As a result, the speed of sound is much higher in helium. By inhaling helium you are effectively increasing the speed of the sound of your voice. The configuration of your vocal tract does not change, however. If you increase the speed of a sound while keeping its wavelength constant, you increase the frequency of that sound. (Think of it as a sort of Doppler effect.) Since each element of speech is composed of a pattern of several frequencies, altering the speed of sound distorts that pattern. Result: you sound like Donald Duck.\n\nNote that the pitch remains the same because your vocal folds are vibrating at the same frequency as when you were breathing air. Contrary to many explanations I have read, helium does not significantly affect the vibration of your vocal folds. To repeat yet again, helium drastically changes the timbre of your voice without having any significant effect on its pitch. \n\nI have heard reports of wacky chemistry professors (how's that for redundant?) inhaling balloons full of xenon gas. Because pure xenon is much denser than air, the speed of sound through xenon is slower, and inhaling xenon lowers the resonant frequencies of your vocal tract. Some web sites recommend wearing a cowboy hat while speaking in a "xenon voice" for maximum comedic effect. Yee ha. \n\nOne final note: inhaling helium is not a terribly healthy thing to do. Every time you inhale pure helium, you are not inhaling oxygen. And for the love of Pierre-Jules-Céésar Janssen (the first man to find evidence for the existence of helium), do not inhale helium from a pressurized tank! In addition to risking serious damage to your lungs, you could wind up with helium bubbles in the arteries that supply blood to your brain. This is known as a cerebral arterial gas embolism and can lead to stroke-like symptoms including, of course, death.

No, it doesn't damage the voice box...it has a different density, thus sound travels faster in helium

Its because of the production of the acids in stomach; namely the gastric juice. As a result the gases so formed try to escape. This is the cause of the various strange sounds our stomach produce.

It is like tinkk just said you never hear your voice as others hear it that is why it sounded wierd to you.  However if you played it for someone you know they would likely recognize it as your voice and not think it was so wierd.\n\nOne other way to kind of hear what you sound like is to cup your hand beind your ear and bend your ear slightly forward, then listen to yourself.  \n\nWhen you are singing you could also wear some headphones that will play what the microphone is recording, that's your voice.

Helium alters your vocal cords (temporarily, as I'm sure you discovered), causing the pitch of your voice to arrive.\n\nWhile it can be a lot of fun, repeated exposure to your larnyx isn't good for it.

Just water at room temperature, nothing else, any citric would cause temporary damage to the vocal chords..☺

You poor thing!  :-)  It's also possible there could be a medical problem affecting your breath.  Here's a link to some basic info about halitosis.  Good luck to future smooching!
