A robocall is a phone call that uses a computerized auto-dialer to deliver a pre-recorded message, as if from a robot. Robocalls are often associated with political and telemarketing phone campaigns. Some robocalls use personalized audio messages to simulate an actual personal phone call. Criminals and dishonest robocallers often alter or spoof the calling number of their outbound telephone calls in order to deceive a called party. This deception increases the chance that the called party will answer a robocall. In other cases, the spam calls may be more malicious. This proposal provides an artificial intelligence (AI)-based interactive and intelligent technique that utilizes a voicebot to detect spam calls by analyzing various answer/response patterns (or contexts) of callers in order to add such callers to a deny list without any user intervention.
