Microsoft's Acoustic Caller ID Patent

Posted by samzenpus on from the who-do-you-sound-like-today dept.

theodp writes "A new patent granted to Microsoft Tuesday for automatic identification of telephone callers based on voice characteristics covers constructing acoustic models for telephone callers by identifying words or subject matter commonly used by callers and capturing the acoustic properties of any utterance. Not only that, it's done 'without alerting the caller during the call that the caller is being identified,' boasts Microsoft in the patent claims."

    The only difference here (aside from what agencies have been doing since the 1960's) is that this analysis seems to be done in real time, rather than offline? I mean, haven't monitoring people been able to tell who is speaking based on sound synthesis since forever?

    What's the purpose of caller ID after I've picked up the phone?

    If someone had acquired some of your personal information, and then tried to impersonate you, an automated voice recognition system could be useful by raising an alarm, or at least giving a percentage of how much their voice is like yours.

    It could be true, too.
