The song of Coppery-chested Jacamar is similar to that of other species of Galbula; it is described as "a series of gradually rising pee notes that seem (unlike many other Galbula) usually not to end in a chipper" (Ridgely and Greenfield 2001b) and as "a rising series of wee notes, sometimes ending in a descending rattle" (Lane, in Schulenberg et al. 2010).

The call is "a sharper peeyk" (Ridgely and Greenfield 2001b) or "a weet note, singly or in a series" (Lane, in Schulenberg et al. 2010).
