Gimi, also known as Labogai, is a Papuan language spoken in the Eastern Highlands Province in Papua New Guinea. 23,000 speakers (2000 cited) speak the Gimi language.

Gimi has 5 vowels and 12 consonants.^[2] It has voiceless and voiced glottal consonants where related languages have /k/ and /ɡ/. The voiceless glottal is simply a glottal stop [ʔ]. The voiced consonant behaves phonologically like a glottal stop, but does not have full closure. Phonetically it is a creaky-voiced glottal approximant [ʔ̞].^[3]

/p/ occurs word initially only in loanwords.

/b/ can surface as either [b] or [β] in free variation.

/z/ becomes [s] before /ɑ/.

/t/ and /ɾ/ tend to fluctuate with one another word initially.

The syllable structure is (C)V(G), where G is either /ʔ/ or /ʔ̞/.

The final vowel of a word takes either a level or falling tone. The falling tone is written with an acute accent.

Gimi uses the Latin script.^[2]
