Abstract
Disclosed is an apparatus and method for prevention of interferences from speech sounds in telephony. The apparatus comprises a cipher generation unit, an automatic speech sound sending digital processor and an incoming call filter unit. When a receiver receives an incoming call from a sender, a cipher is generated. Next, the receiver sends a speech sounded cipher to the sender based on the generated cipher. Responsive to the speech sounded cipher, the sender inputs a response cipher with reference to the speech sounded cipher. Finally, the inputted cipher and the cipher generated at the receiver end are compared, so that the receiver may determine if the incoming call is a voice-over-internet protocol (VOIP) SPAM and should be answered.

An apparatus for prevention of interferences from speech sounds in telephony, comprising:
- a cipher generation unit adapted to generate a cipher based on an incoming call from a sender end;
- an automatic speech sound sending digital processor adapted to play a cipher speech sound to the sender end;
- and
- an incoming call filter unit adapted to compare a cipher inputted by the sender end with the cipher generated at the receiver end, wherein the compared result is used for a determination as to if the incoming call should be answered.
A method for prevention of interferences from speech sound in telephony, comprising the steps of:
- generating a cipher at a receiver end in response to an incoming call made from a sender end;
- sending a speech sounded cipher from the receiver end to the sender end based on the generated cipher;
- inputting a response cipher based on the speech sounded cipher at the sender end;
- and
- comparing if the response cipher be matchable with the cipher generated at the receiver end so that the receiver end may determine if the incoming call should be answered.
