A voiced alveolar affricate is a type of affricate consonant pronounced with the tip or blade of the tongue against the alveolar ridge (gum line) just behind the teeth. This refers to a class of sounds, not a single sound. There are several types with significant perceptual differences:
The voiced alveolar fricatives are consonantal sounds. The symbol in the International Phonetic Alphabet that represents these sounds depends on whether a sibilant or non-sibilant fricative is being described. The symbol for the alveolar sibilant is z , and the equivalent X-SAMPA symbol is z.
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 ...
the grooved alveolar consonants (e.g., [s z]), such as the s and z occurring in English words like sip and zip; The first three types of sounds above have a convex tongue shape, which gives them an additional secondary articulation of palatalization. The last type has a groove running down the center line of the tongue, which gives it a strong ...
Typically the position of the sound within a word is considered and targeted. The sound appears in the beginning of the word, middle, or end of the word (initial, medial, or final). Take for example, correction of an "S" sound (lisp). Most likely, a speech language pathologist (SLP) would employ exercises to work on "Sssssss."
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.
[citation needed] To native speakers, the English alveolar /t/ and /d/ sound more like the corresponding retroflex consonants of their languages than like dentals. [ citation needed ] Spanish /t/ and /d/ are denti-alveolar , [ 2 ] while /l/ and /n/ are prototypically alveolar but assimilate to the place of articulation of a following consonant.
Nonetheless, there are a few languages that lack them. A few languages on Bougainville Island and around Puget Sound, such as Makah, lack nasals and therefore [n] but have [t]. Colloquial Samoan, however, lacks both [t] and [n] but has a lateral alveolar approximant /l/. (Samoan words written with t and n are pronounced with [k] and [ŋ] in ...
