Articulatory phonetics aims to describe the features of specific phones based on their production features (Bauman Waengler, 2020)
Vowels are produced with an open vocal tract, allowing for an unobstructed airflow from the vocal folds to the lips, making them "open" sounds. They are categorized by front or back, high or low positions of the tongue and lips as shown in the vowel quadrilateral chart below.

"Three phonetic categories are used to characterize consonants: voicing features, place of articulation, and manner of articulation."
"Voicing is the term used to denote the presence or absence of simultaneous vocal fold vibration."
"Place of articulation describes where the constriction or narrowing occurs for the various consonant productions."
"Manner of articulation refers to the type of narrowing that the articulators produce for the realization of a particular consonant."
