Furthermore, the different techniques that parrots and budgeri-
gars employ for imitating the human voice are most effective. Like
humans, parrots have thick tongues that enable them to produce
sounds resembling ours. Sound is produced by blowing air through
two separate places in their syrinx, and at the same time producing
the independent sounds required to produce consonants. The initial
sound from the syrinx is shaped with the help of the throat, and then
in the mouth with the tongue. In their research studies with grey
parrots, Dianne Patterson and Irene Pepperberg reached important
conclusions on vowel production: Due to the radically different
anatomy of this parrot’s vocal organ, even though they lack teeth
and lips, they can produce sounds that closely resemble sounds pro-
duced by humans.

Indeed, parrots and budgerigars can quite clear-
ly imitate sounds such as “m” and “b,” which we normally
produce with the help of our lips.
Budgerigars, however, due to their small size, are not
able to use the same technique as par-
rots. Using their syrinx to create fre-
quencies from 2,000 to 3,000 Hz, they
then add on a second vibration. This
