The disclosed is a method to perform an automatic phone screening based on the caller's voice. It involves two steps, a registration step and an identification step. The first call from, for example, a telemarketer is received by the callee. By talking to the telemarketer, the callee decides to not accept further calls from this telemarketer. The callee can initiate the registration of this telemarketer's voice into the voice print database.

This will enable the callee to reject the call based on who is making the call instead of where the call is made from. The disclosed method can be implemented on an intelligent device either attached to a telephone or embedded within a telephone. Here are the steps for the device to answer a call. Step 1: The device will pick up the call before ringing the phone. Step 2: The device plays back a pre-recorded message to invite the caller to say something. Step 3: The device performs the comparison of the caller's voice against the built in voice print database. Step 4: If a match is found, the device plays back a pre-recorded message to the caller rejecting the call. The telephone will not ring. Step 5: If no match is found, the device will ring the phone. Step 6: The callee picks up the phone and talks to the caller. Once the callee decides th...
