Voice: The Allpahuayo antbird's song is "a moderately paced, slightly decelerating series of monotone whistles usually with a stuttered, higher-pitched introductory note: hi'hi hew-hew-hew-hew-hew-hew-hew". Its calls include "a descending whine or whistle, a harsher tchah, a rising, melodic k'lee? and a musical, rising-falling sputtering rattle: pur'E'E'E'e'e'rr".
