'Eavesdropping device' is well-known for picking up sounds and voices in concealment. It is commonly used in approaches such as surveillance in police‟s investigation or security purposes. Even though it is readily available in the market, it is difficult to identify and focus on a specific group‟s conversation when there are a lot of noise and interference involved. Hence, this project hopes to address this problem by creating a highly intelligent system to automatically filter out unnecessary noise and information whenever a target is fixed.
