Shame there's some disquiet over the issue of male and female vocal chords. Shame, as no one seems to meaning to cause offence. Shantel, Kelly the Trans Rebel and Alice in Genderland are all right, you're all on the same team!
Male vocal chords tend to be larger than female vocal chords upon hitting puberty, however there is (like with other sexually diamorphic traits) the propensity for overlap. From what I've read, the female vocal chord size when at its largest is the smallest that an adult natal male's can be. I've noticed that petite or very slim women also have more visible vocal chords simply because they are skinnier around the neck.
So equally valid to say that -Having prominent vocal chords & larynx will not neccesarily "out" you as MAAB, if you happen to be within the female range and/or have many other facial attributes well within female range.
However, larger vocal chords, Adam's apple and larynx, can be seen as a masculine trait and therefore if there's any doubts to whether your a cis-female - the chords can give you away. Its definitely something that people seem to look for. Vast majority of the public WILL see larger vocals chords and become suspicious, IF there is reason to make them doubt the birth sex in the first place. This is not a generalisation either, this is what happens in practice. Doesn't have to define whether people will see you as a cis-female or not though, but it can go a long way for their basing their opinion, potentially.
Quotei heard you can have your adams apple raised up which not only hides it but also increases the pitch of your voice
That's very intriguing Lucy! Never heard of that before. Please do tell... :-)
