Women also undergo voice change, just less pronounced.

Now the problem turns into being able to tell men from women.

EDIT: this of course isn't a serious proposition.

Then again I wonder what effect this would have implemented on e.g. a porn site. Women also watch porn, but with enough tuning I think it shouldn't produce too many false positives - if only due to the demographic of the users.

Surely the vocal cords and larynx of an adult woman are on average larger than those of a 10yo boy?

The AGEWARDEN system is ^^ agnostic and answers a simple question only: Is this human over or under 18?

From my research, each person is incredibly unique :)
