How to detect cyborgs

Domu is bugging Pia by echoing everything she says using a robot intonation.  Pia is getting pretty annoyed:

Pia: DADDY! Domu is copying what I say!!!!

Dominic: Daddy..Pia..Is...Copying...What...I...Say.

Pia: STOP IT!!!!!!!!!!!!!!!!!!

Dominic: Stop...It.

Pia: You're not  a robot!

Dominic: You're...Not...A...Robot.

Pia: You're not a robot!  Robots aren't smelly!  No robot is smelly!
