Similar worries. Different starting points.
Online discussion often starts with pitch and jumps straight to puberphonia. Clinicians start more broadly: what does the voice sound and feel like, how does it function and what does examination show?
A→B→C→D→
Distinctly persistent falsetto
The speaking voice remains clearly falsetto or prepubertal in character after puberty.
Higher adult male voice
The voice is recognisably adult and male, but sits higher than the speaker wants.
Another voice problem
Strain, weakness, breaks, pain or inconsistency may point toward another functional, structural or neurological issue.
Distress about a typical voice
Recordings, comparison and masculinity concerns can create real distress even when the voice itself is typical.
