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.[clarification needed]
