Microsoft's Acoustic Caller ID Patent
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."
People don't pay attention because usually they get a bunch of shit and have already been ignoring a lot of hold music / hold advertisments by the time they get to talk to someone.
