Maybe you're not that stupid or ignorant, but people might get the impression that to do the trick you have to breathe in helium, which is dangerous. Of course if you're talking about a 90% oxygen mixture, that makes a difference! Talk like Mickey Mouse for a few seconds. Fill your mouth cavity with helium from a balloon. Only that it appears less dangerous than inhaling a lungful of helium. This forum is pretty strict about giving advice for liability reasons, so I am NOT going to say that the following procedure is safe, nor do I recommend doing it. To configure the Helium Voice you will have to adjust Pitch as follow: Mix I 100, Pitch 70 and Humanizer I OFF. To create an helium voice you will have to select the Pitch generator. breathe it into your lungs) in order to produce the voice effect. To create your own Helium Voice Changer without Helium you have to follow these steps: Open Voicemod PRO and go to the Voice Maker function. It is highly dangerous to inhale any asphyxiant gas. That’s a sign to stop.Īnd whatever you do, don’t ever inhale helium directly from one of those pressurized tanks.First of all, DO NOT INHALE HELIUM. If you’ve ever tried it, you may have gotten a light-headed feeling from a few inhalations. In fact, breathing helium continuously can cause asphyxiation within a few minutes. That’s because while you’re inhaling helium, your body isn’t getting the oxygen it needs for normal respiration. Inhaling a few breaths of helium is usually harmless, but breathing a lot can be dangerous. As soon as regular air returns, your voice returns to normal. The effect lasts only as long as there’s helium around your vocal cords. It’s what makes you sound more like Donald Duck. This changes the resonant frequencies of your vocal tract by making it more responsive to high-frequency sounds and less responsive to lower ones. Because helium is lighter than air, sound waves travel through it faster. Normal air is made up mostly of nitrogen, which has a mass roughly seven times greater than that of helium. Even when your vocal tract is filled with helium, your vocal cords are vibrating at the same frequency as usual. Some people think that helium changes the pitch of your voice, but that’s not the case.The vibration frequency of the vocal cords doesn’t change. The resonant frequencies established by the vocal tract are what makes your voice unique. For example, a piano sounds different from a guitar even when they are playing the same note because of timbre. The shape of the vocal tract affects the timbre, which is what distinguishes one sound from another. The pitch is determined largely by the length and tension of the vocal cords. The higher the rate of vibration of the vocal cords, the higher the pitch of your voice. This can be tried in real life, although it should be noted that helium displaces oxygen in. The vibration of the vocal cords influences the pitch, which is how high or low it sounds. A mouse in the wainscotting Well squeaked, mouseThe Doctor, Doctor Who, The Robots of Death Because helium is lighter than air, when you inhale it and try to talk it causes the vocal cords to vibrate at a higher frequency, resulting in reedy, duck-like voices which can be used to great comic effect. The final sound of your voice that people hear is determined by the combination of the vibrating vocal cords along with the shape of your vocal tract. Those frequencies are known as resonant or natural frequencies, and in the case of your voice, those frequencies are determined by the shape and size of the vocal tract. A resonator strengthens vibrations at certain frequencies. If you play an instrument, you might be familiar with resonators. The vocal tract acts as a resonator, or re-sounder. Instead, sounds created by the vocal cords pass through the vocal tract before they become the human voice we hear. But we don’t! If we did, we’d only hear a buzzing sound at that point. Many people think we hear sounds directly from the vocal cords. And when the vocal cords vibrate, they produce sound. When air passes between the vocal cords, it causes them to vibrate. When you speak, air travels up from your lungs and through the larynx. The vocal cords are two folded mucous membranes stretched across a structure called the larynx.
