Zhangzhou Southern Min employs the airstream mechanism of glottalic ingressive as a contrastive feature in its onset system. However, their realisations are highly diverse with eleven phonetic variants that can be derived from three implosive phonemes (/ɓ, ɗ, ɠ/). The allophonic variations are regressively motivated by three driving factors comprising the nasal [Ṽ], labial-velar [u, w], and palatal [i, j] characteristics of subsequent segments. Several processes that include labialisation, nasalisation, lenition, laminalisation, dentalisation and palatalisation have been found to trigger alternation on the airstream mechanism, manner of articulation, and place of articulation of related sounds, resulting in diverse phonetic outputs of the three implosives phonemes that can be captured using phonological rules.
