The song of Black-girdled Barbet is "a steadily accelerating series of hollow boo notes (ca. 7-8 s) that is similar to that of Striated Antthrush (Chamaeza nobilis) but lacking the distinctly slowed woop woop woop woop terminal notes" of the song of the antthrush (Zimmer et al. 1997).

Calls of Black-girdled Barbet include "a staccato series of rough notes that could be translated as rerk erk erk erk erk or rok rok ock ock and which is frequently given by foraging birds" (Zimmer et al. 1997); and "a peculiar grating rattle (with the quality of tearing thick cardboard) often given by foraging birds when they make longer flights (as in crossing the road or in leaving a given area)" (Zimmer et al. 1997).
