The stops /p k t/ are sometimes phonetically aspirated in coda: /pɨtit/ ‘one’. The approximant /j/ surfaces as preceding one of /ɨ̃ ĩ/, as in /mpɔ-jĩ/ ‘meat’, /pa mũ jɨ̃/ ‘I sat down’. /n/ is optionally assimilated to before /k/, as in ~ ‘small’. The voiced labial fricative and the glottal stop have been attested in one word each, ‘bird’ and ‘hen’.
Available complex onsets include /pɾ kɾ mp/ (and possibly others). The maximum syllable in Kỳikatêjê is /CCVC/.
