Since vowels are produced with an open vocal tract, the point where their production occurs cannot be easily determined. Therefore, they are not described in terms of a place of articulation but by the relative positions in vowel space. This is mostly dependent on their formant frequencies and less on the specific tongue position and lip rounding.
Vowels are unique in that their main features do not contain differences in voicing, manner, or place (articulators). Vowels differ only in the position of the tongue when voiced. The tongue moves vertically and horizontally within the oral cavity. Vowels are produced with at least a part of their vocal tract obstructed. [3]
Most vowels are voiced (i.e. the vocal folds are vibrating). Except in some marginal cases, the vocal tract is open, so that the airstream is able to escape without generating fricative noise. Variation in vowel quality is produced by means of the following articulatory structures:
The vocal cords are composed of twin infoldings of 3 distinct tissues: an outer layer of flat cells that do not produce keratin (squamous epithelium). Below this is the superficial layer of the lamina propria , a gel-like layer, which allows the vocal fold to vibrate and produce sound.
There are two complementary definitions of vowel, one phonetic and the other phonological.. In the phonetic definition, a vowel is a sound, such as the English "ah" / ɑː / or "oh" / oʊ /, produced with an open vocal tract; it is median (the air escapes along the middle of the tongue), oral (at least some of the airflow must escape through the mouth), frictionless and continuant. [4]
Voiceless sonorants are rare; they occur as phonemes in only about 5% of the world's languages. [3] They tend to be extremely quiet and difficult to recognise, even for those people whose language has them. In every case of a voiceless sonorant occurring, there is a contrasting voiced sonorant.
In Uyghur, the phoneme /ʁ/ occurs with a back vowel. In the Mongolian language, /x/ is usually followed by /ŋ/. [45] The Tuu and Juu (Khoisan) languages of southern Africa have large numbers of guttural vowels. These sounds share certain phonological behaviors that warrant the use of a term specifically for them.
The vibration produced is an essential component of voiced consonants as well as vowels. If the vocal folds are drawn apart, air flows between them causing no vibration, as in the production of voiceless consonants. [6] The glottis is also important in the Valsalva maneuver. Voiced consonants include /v/, /z/, /ʒ/, /d͡ʒ/, /ð/, /b/, /d/, /ɡ ...
