Duest and dialogues (verbal, whistle, verbal-species-specific, and ver
bal-behavioral) between humans and captive birds are considered (Commu
nication between a man and bird including nonverbal signals made by at
least one partner is defined here as a duet). Three-dimensional graph
s are provided for the speech replicas of the man and bird and for the
species-specific response signals of birds. KAPROS-01 software was us
ed as an acoustic analyzer, It has been proposed that acoustic communi
cation between biocoenosis members and, specifically, antiphonal singi
ng is a prototype of duets and dialogues between humans and captive bi
rds, It has also been proposed that associative relations between soun
d signals and corresponding situations are inherent in birds in nature
, and this markedly facilitates formation of focused, improvised and m
atched dialogues with nonfixed replicas between humans and captive bir
ds.
