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!
