Synthetic and Recorded Vocals: A Careful Listening Framework
Listen for relationships, not isolated imperfections.

A structured vocal pass
Compare breaths with phrase length, consonants with surrounding ambience, vibrato with musical emphasis and repeated lines with one another. A single strange syllable is weak evidence; a pattern across independent moments is more informative.
Why the cues disappear
Pitch correction, comping, denoising, saturation and lossy encoding reshape human vocals. Generated voices can be re-sung or layered. Language, genre and deliberate vocal effects also change what a listener expects.
The important questions may be non-acoustic
Voice likeness raises consent and identity issues whether a whole song is generated or not. Ask for permissions, performer credits and session material. A whole-mix detector cannot establish that a specific person's voice was cloned.
