How do we speak?

Speech distinguishes humans from other apes. The physical aspect of speech pertains to the vocal chords, the larynx, the positioning of the tongue and the lips. Each of these plays a vital role in helping humans to speak. Of course, the brain coordinates the movement for speech functions as well as other functions.

The vocal chords

The essential human speech or sounds are made when air is passed over the two vibrating elements known as the vocal chords. When the right amount of tension is applied on the vocal chords, the tone of the speech can become higher or lower. Modulation of the speech is done by the larynx. In this, the mouth and the nose chambers that are present help the larynx is modulating the speech. The Vocal cords are present inside the throat and can be used for producing various types of sounds.

Vocal cords, also known as vocal folds, are made up of twin introversions of mucous membrane and these remain stretched horizontally across the larynx. Vocal cords vibrate and modulate the flow of air. When we talk, the will also stiffen and also move closer to each other. Finally, the sounds and the words are produced when the tongue is moved in a particular direction along with the positing of the lips. The volume of the sounds is essentially controlled by increasing or decreasing the amounts of air that would pass through the vocal chords.


It is also known as voice box, positioned among pharynx and trachea and is a 2-inch-long, tube-shaped organ in the neck. Larynx is extensively used for talking and even breathing. It is also essential for swallowing. The external wall of cartilage of larynx is responsible for the shape of the “Adams apple.”


Brain is the centre that controls speech and hearing as well. In fact, both are even interconnected. It controls the phonetic sounds and the articulation of the sounds.

Human speech also undergoes changes when a human reaches puberty. This is especially pronounced for boys. Since the vocal chords become thicker and the resonance chamber also increases, the voice modulation and quality changes. This is the reason, that pubescent boys sound different and their voice sounds hoarse or heavy. At times that voice will also sound squeaky and funny. This is because, at this time, they are also learning to modulate their vocal chords again.

The organs that are involved in the speech process for humans

Our lips, teeth, tongue and the mouth are used in various positions to emanate the sounds that we want to make. The uvula located inside our mouth is used specifically when we want to make some guttural noises. The uvula is also useful for making speaking the nasal tones by stopping the air from going inside the noise.

The vibrations that emanate from the vocal chords are controlled by the glottis and this helps us to make various sounds as well. The tongue taps and even touches the alveolar ridge and the hard palate inside our mouth when we are speaking and making different noises in that process.

    I have no idea how familiar you are with what I’m about to say you didn’t give any info about how good you are so if you aldeary know this stuff, just ignore it. One of the most important things with singing is being able to use your diaphram. The diaphram is the muscle right where your “abs” are. This muscle is aboslutely required if you want to sing or play an instrument well. You use it mostly to push air out of your lungs.Before you sing anything make sure to take a DEEP breath (this is more complicated than most people think. First, fill up the bottom of your lungs with as much air as you can hold. You should make a deep, gasping for air sound when you do this. Next, fill up the top of your lungs. When you do that, you should be making a higher-pitched air sound. You’ll get the hang of it eventually.)Next, when you sing a note, push out the air with your diaphram. Pretty much just suck in your stomach slowly, so you’re forcing a lot of air out of your lungs. Chance are, you won’t notice much of a difference at first, but once you get the hang of it, you’ve taken a big leap. Remember, there aren’t any over-night tips that are going to suddenly make you sing better. The only way to get better is practice-practice-practice.
