Sulcalization (from Latin: sulcus 'groove'), also called internal rounding, in phonetics, is the pronunciation of a sound, typically a sibilant consonant, such as English /s/ and /z/, with a deep groove running along the back of the tongue that focuses the airstream on the teeth, producing a more intense sound. This is accomplished by raising ...
Its manner of articulation is sibilant fricative, which means it is generally produced by channeling air flow along a groove in the back of the tongue up to the place of articulation, at which point it is focused against the sharp edge of the nearly clenched teeth, causing high-frequency turbulence.
[citation needed] Its sound is between [s] and . The voiceless alveolar non-sibilant fricative [θ̠] or [θ͇], using the alveolar diacritic from the Extended IPA, [1] is similar to the th in English thin. It occurs in Icelandic as well as an intervocalic and word-final allophone of English /t/ in dialects such as Hiberno-English and Scouse.
In the vowel diagram, convenient reference points are provided for specifying tongue position. The position of the highest point of the arch of the tongue is considered to be the point of articulation of the vowel. The vertical dimension of the vowel diagram is known as vowel height, which includes high, central (mid), or low vowels.
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.

Schematic mid-sagittal section. Features of the voiced retroflex sibilant: Its manner of articulation is sibilant fricative, which means it is generally produced by channeling air flow along a groove in the back of the tongue up to the place of articulation, at which point it is focused against the sharp edge of the nearly clenched teeth, causing high-frequency turbulence.
The voiced alveolar trill is a type of consonantal sound used in some spoken languages. The symbol in the International Phonetic Alphabet that represents dental, alveolar, and postalveolar trills is r , and the equivalent X-SAMPA symbol is r. It is commonly called the rolled R, rolling R, or trilled R.
In phonetics, palatalization (/ ˌ p æ l ə t ə l aɪ ˈ z eɪ ʃ ən / ⓘ, US also /-l ɪ-/) or palatization is a way of pronouncing a consonant in which part of the tongue is moved close to the hard palate.
