Within the science known as linguistics we find a very important branch that is known as phonetics. Phonetics is dedicated to studying the sounds emitted by the human voice, its formation and its variants depending on the position of the different parts of the speech system that include from the tongue to the most internal organs in the throat.
When one learns a non-native language, phonetics is always a fundamental piece of the learning process since it is the part of the language that allows us to pronounce each sound, each word in the correct way, leaving aside the typical intonation of the language that one possessed from birth and pronouncing words just as natives do.
Phonetics is especially interested in analyzing how the human being produces the different sounds that are later used in speech. In this sense, phonetics creates different symbologies that seek to represent each of these sounds in order to make them easier to recognize and analyze.
Thus, each word is made up of a specific set of sounds that are generally represented by different symbols than those represented by the letters of the alphabet. To understand them, phonetics also seeks to understand how each sound is produced by the different parts of the mouth and the vocal cord system in order to easily repeat them later.
Phonetics has several sub-branches that have to do with different applications and ways of carrying out the use of the language. Thus, some of the existing branches within phonetics are experimental, articulatory and acoustic phonetics. All of them try to analyze the physical phenomenon of speech within different parameters that have to do with how sound is produced, but also with how sound is sent abroad.
