The changeable hawk-eagle is often largely silent but in breeding season it may readily call, both from their perch or on the wing. Like many diurnal raptors, their calls are a form of high-pitched scream. The shrill ringing and loud call of the changeable hawk-eagle is various described in pattern of ''yeep-yip-yip-yip'', rising ''kwip-kwip-kwip-kwee-ah'' and penetrating ''klee-leeuw'' (for birds from the [[Sunda islands]]). Ascending ''kri-kri-kri-kree-ah'' and ''kreeee-krit'' with much stress on the elongated first syllable are similar. From western birds  from [[India]] and [[Sri Lanka]], the call is a slightly different ''ki-ki-ki-ki-ki-ki-ki-keee'', beginning short, rising in crescendo and ending in long, drawn-out scream. In northern [[India]] and [[Malaysia]], the calls of this species have variously been compared to those of the [[Eurasian curlew]] (''Numenius arquatus'') and the [[crested serpent eagle]] (''Spilornis cheela'').<ref name= Ferguson-Lees/><ref name= Naoroji/><ref name="Grimmett">{{Cite book |last1=Grimmett, R. |title=Birds of the Indian Subcontinent: India, Pakistan, Sri Lanka, Nepal, Bhutan, Bangladesh and the Maldives |last2=Inskipp, C. |last3=Inskipp, T. |publisher=Bloomsbury Publishing |year=2013}}</ref>
