When the vocal cords are stretched tight and close together, they vibrate rapidly, and their vibration produces voice we hear in articulating vowels and voiced consonants.

In the production of voiceless consonants the vocal cords are relaxed and apart. When we speak, our lungs push air up past the vocal cords and through the rest of the vocal tract (the space in the throat, mouth and nose where sound is produced). The most important organs of speech include the lips, teeth, tongue, alveolar ridge, hard palate, soft palate (or velum), uvula and glottis. In order to pronounce the sounds of English correctly, you should have a general notion of organs of speech (or articulators) and know what position they take in producing different sounds.
