There are two linguistic strata in Taliabo, Central Maluku and Celebic, and it is not yet clear which group it belongs to, though Glottolog classifies it as Celebic.
The Soboyo dialect of Taliabo is notable for preserving Proto-Malayo-Polynesian*h, but only in word-initial position.
All stop sounds (except for /ʔ/) and fricatives /s,ʃ/, may also be prenasalized in both word-initial and word-medial positions as /ᵐb,ⁿd,ᶮdʒ,ᵑɡ/.[3][4]
