The word phoneme comes from the Greek “φώνημα” which means “sound of the voice”, this alludes to the theoretical units of reasoning to learn leveling “phonic” which is relative to the voice or speech sounds, “phonological” means relative to her, of a human language.

The phoneme is each of the properties selected for the argument of a phonological system fixed to a set of phonetic features that can be defined by the sounds of the language, at the beginning it has no term for how good the difference that they compose can be. these characters, the phonological system is a pair of F= (F,R) in which F is a list of phonemes and R is a set of rules that, depending on the context of viewing the phonemes, define the phonetic characters and count with the sounds of a language.

In the consonant sounds as well as the point of articulation the following can be found: the labials, labiodentals, palatalals, velars, uvulars, pharyngeals, glottals and within the coronals are the interdental, dental, alveolar, postalveolar, retroflex.

Labial, they are coherent that are linked with both lips (bilabial union) or with the lower lip and its teeth (labiodental union).

Coronal, is the direction taken to the dental crown in which they are divided into apical, which is a sound produced that covers the passage of air through the apex of the tongue, the laminal is a flat front extension that is located behind the tip of the tongue that prevents the passage of air through the sheet.
