Allophone of /d/ before /i, ĩ/ (like [dʒ ~ dʑ], even when [i, ĩ, j] is not actually produced), or as a result of vowel elision leading to sandhi of unstressed /e ~ ɨ ~ i/, even past the development of the [dʒ ~ dʑ] allophony. Use in Brazil is in current expansion.
The voiced alveolar fronted sibilant affricate (commonly called voiced dental sibilant affricate) is a type of consonantal sound, used in some spokenlanguages. In the International Phonetic Alphabet it's commonly represented as ⟨d̪͡z̪⟩ and ⟨d͡z̪⟩, combinations of the letter for the voiced alveolar sibilant affricate and a diacritic (or two) indicating dental articulation. However, teeth actively participate in the articulation only in case of the stop component, which is laminal denti-alveolar. The fricative component, the features of which are used to describe the affricate is laminal alveolar fronted (post-dental). Therefore, a notation ⟨d̟͡z̟⟩ and ⟨d͡z̟⟩ (combinations of the letter for the voiced alveolar sibilant affricate and a diacritic (or two) indicating fronted articulation) would be more appropriate. This article uses ⟨d̪͡z̪⟩ for simplicity.
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.
