Voiced alveolar affricate
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 sibilant affricate  is the most common type, similar to the ds in English lads. The voiced alveolar non-sibilant affricate , or  using the alveolar diacritic from the Extended IPA, is found, for example, in some dialects of English and Italian. The voiced alveolar retracted sibilant affricate

Voiced alveolar sibilant affricate

The voiced alveolar sibilant affricate is a type of consonantal sound used in some spoken languages. The sound is transcribed in the International Phonetic Alphabet with  or  (formerly ). Features
Features of the voiced alveolar sibilant affricate:

The stop component of this affricate is laminal alveolar, which means it is articulated with the blade of the tongue at the alveolar ridge. For simplicity, this affricate is usually called after the sibilant fricative component. There are at least three specific variants of the fricative component:
 Dentalized laminal alveolar (commonly called "dental"), which means it is articulated with the tongue blade very close to the upper front teeth, with the tongue tip resting behind lower front teeth. The hissing effect in this variety of  is very strong. Non-retracted alveolar, which means it is articulated with either the tip or the blade of the tongue at the alveolar ridge, termed respectively apical and laminal. Retracted alveolar, which means it is articulated with either the tip or the blade of the tongue slightly behind the alveolar ridge, termed respectively apical and laminal. Acoustically, it is close to  or laminal . Occurrence
