Gadsup is a Kainantu language spoken by the people of the same name in Papua New Guinea.

• /ɸ, β, s, ɾ, x/ become plosives [p, b, t, d, k] when preceded by /N, ʔ/, but initially and medially they are [/ɸ, β, s, ɾ, x, ɾ].^[3]

The phonology of Akuna Gadsup is similar to Ontena Gadsup, except voiceless plosives don't lenite initially, but they do medially.^[3]

/ɐ/ can also be heard as [ʌ̈].^[5]
