Korebaju (ISO639-3: coe) [́kòrèβàhɨ́] is a tonal language spoken in the foothills of the Colombian Amazon. Three field surveys carried out between 2017 and 2019 with six native speakers (3 females and 3 males) from the same village provide a set of glottal productions at both phonetic and phonological levels. This study focuses on the four types of glottal units we have found in this language: A set of vowels /aʔ/, /eʔ/, /oʔ/, [iʔ] and [ɨʔ] including 3 phonemes; the glottal stop [ʔ] and the consonant [*] transcribed and described as a creaky voiced glottal approximant by [1]. Both consonants occurred in intervocalic contexts and can be analyzed as a suprasegmental feature [constricted glottis] which marks the syllable onset. Finally, we have also found a clear and systematic burst which accompanies the release of the nasal consonants [mʔ, nʔ, ɲʔ]. No change was found in the EGG signal for these consonants suggesting an abrupt release of the aeroacoustic pressure.
