Nonexplosive Stop

In phonetics and phonology, nonexplosive stops are non-pulmonic (called "non-obstruent") stop consonants that lack the pressure build-up and burst release associated with pulmonic stops. They are reported to occur in Ikwere, an Igboid (Niger–Congo) language of Nigeria.

Ikwere's two nonexplosive stops, transcribed as voiced ⟨ḅ⟩ and pre-glottalized ⟨ʼḅ⟩, correspond to labial-velars /k͡p/ and /ɡ͡b/, respectively, in most other Igboid languages, and implosives /ɓ̥/ and /ɓ/ in some varieties of Igbo. Ikwere's stops resemble both, in that they are velarized and have a non-pulmonic airstream mechanism.
