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:
Features of the voiced alveolar sibilant affricate:
Its manner of articulation is sibilantaffricate, which means it is produced by first stopping the air flow entirely, then directing it with the tongue to the sharp edge of the teeth, causing high-frequency turbulence.
The stop component of this affricate is laminalalveolar, 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 [z] 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 [ʒ] or laminal [ʐ].
Its phonation is voiced, which means the vocal cords vibrate during the articulation.
It is a central consonant, which means it is produced by directing the airstream along the center of the tongue, rather than to the sides.
Contrasts aspirated and unaspirated versions. The unaspirated is represented by ज, which also represents [d͡ʒ]. The aspirated sound is represented by झ, which also represents [d͡ʒʱ]. There is no marked difference for either one.
The fricative component varies between dentalized laminal and non-retracted apical. In the latter case, the stop component is laminal denti-alveolar. See Italian phonology
Laminal; varies between retracted and non-retracted. Phonemically, it is a stop–fricative sequence. The example word also illustrates [s̠]. See West Frisian phonology

Features
Its manner of articulation is affricate, which means it is produced by first stopping the airflow entirely, then allowing air flow through a constricted channel at the place of articulation, causing turbulence.
