Phonetics is the study of sounds

make in the production of human language. • • Articulatory phonetics describes how sounds are shape in the vocal tract. This is what we study in LIN 1. • •In order to characterise vowels satisfactorily the cardinal vowel system was introduce at the beginning of the 20th century by the English phonetician Daniel Jones. The basic principle is that extreme positions for the articulation of vowels are take as reference points and all other possible vowel articulations are  in relation to them.
The vowel quadrangle use for the representation.

It is  of vowels is derive from a side view of the oral cavity with the face turn to the left, that is the position of /i/ is maximally high and front, the position of /u/ is maximally high and back while the low vowels /a/ and /ɑ/ are maximal low front and low back respectively. Acoustic phonetics uses physics to describe the sound waves. This is most thoroughly cover in LIN 112. If you are curious, the diagram illustrates this but we will not cover this material in LIN 1. Connecting back to language varieties. The  Each language variety has a unique set of sounds associated with it. The  Linguists analyze phonetics to study language variation, and also. It is  linguistic identities; this is call sociophonetics. • Workplace discrimination. This is  against people due to what they “sound like” e.g, their “foreign accent” (etc.) is discrimination based on phonetics.
