Voxeo announced an initiative last week for voice biometrics which means being able to authenticate a caller based on their voice.
I gave it a spin using PerSay and after sorting out a tiny problem with the VXML referencing the wrong IP address the demo application worked exactly as specified. If anyone wants to try it out it can be reached on sip:email@example.com
when /^234$/ then sys.Dial("sip:firstname.lastname@example.org") # PerSay voice biometrics application.
The flow of the application is:
Ideally I’d like to have a voice biometrics application that didn’t need a numeric ID and could authenticate based on arbitrary conversation. That would make the process quicker and more flexible and open up applications such as being able to translate calls on the fly and associate each caller to a known identity.
