At YouMail, our latest patent-pending innovation is called audio fingerprinting.
News 6 in Orlando did a great job explaining to their viewers what it is and why it matters.
What it does is simple. It lets us quickly compare a new voicemail against every “bad” voicemail that we’ve ever seen (like those left by robocallers). When we find a match, we know the number that left it is a bad guy. So now with a single call leaving a single “bad” message, we can protect our users against all further calls from that number.
That doesn’t solve the robocall problem, but every little bit sure helps!
