Selected languages: Usan
UPSID number: 8630
Alternate name(s): N/A
Classification: Papuan, Trans-New Guinea
The languages has 20 segments
Frequency index: N/A
Sounds: [ⁿb] [p] [b] [ⁿd] [t] [d] [ⁿɡ] [ɡ] [ʔ] [s] [w] [j] [m] [n] [i] [u] [ɛ] [ɔ] [ʌ] [ä]
Comments:

Usan is spoken in the Adelbert Ranges, Madang
Province, Papua New Guinea. Plain and prenasalized voiced
plosives only contrast in medial and final position., /d/
is [d] initially but an alveolar flap elsewhere. A
considerable number of vowel sequences "with one mora
timing" occur; these are interpreted nonetheless as vowel
sequences.
