No offense but this is probably worthless is an adversarial environment.
> I... told it in a higher then normal voice that I was a kid, and it said I was under 18...
Good. If you're pretending to be a kid, you should be blocked. The launch is for sites that allow adults only (should have made that more clear in the post).
Deep voiced teens are THE HARDEST. What I commented earlier about the amount of data available in a clip of audio, that's real - teens have unique signatures that only show in their cohort.
Thanks for testing!
You aren't going to be able to find a set of signatures that keeps out a useful number of <18s that doesn't also flag >18s
Politely disagree with "You aren't going to be able to find a set of signatures that keeps out a useful number..."
That's AGEWARDEN's job and the last year of my life has been diving deep into audio data to find those exact signals.
Good call out and thank you for the pushback :)
So what is a solution? Parents. What about those that don't have parents? Surely they have guardians. Adults who guide the next generation instead of delegating them to technology.
Voice actors, deep fakes, replay attacks (recordings from a TV/computer/phone) - mitigated. As in my earlier comment where teen voices have a signature, these all have unique signatures as well. The ongoing part is staying up-to-date with the latest synthetic (deep fakes/AI generated) as those are getting better each day.
There should exist frequencies impossible to reach for anyone but post-pubescent men.
Of course that would make it teen-age verification at best.
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?
From my research, each person is incredibly unique :)
Yes and no. Like geology, the more you dig into audio, the more is uncovered and available.
A child/teen with a deep voice has very unique perturbations that don't exist in other cohorts across feature sets. Adults may share some characteristics, but not at the levels found in specific age groups.
