The system receives audio input representing a plurality of telephone calls. For at least a portion of the telephone calls, the system analyzes the received audio based on a voice biometrics detection model to identify one or more biometric indicators characterizing a speaker in the analyzed telephone call. The system generates and stores a voice fingerprint characterizing the speaker based on the biometric indicators, and a time of the analyzed telephone call. The system analyzes stored voice fingerprints and times corresponding to speakers in the analyzed telephone calls to determine a frequency of occurrence of each voice fingerprint within an analyzed timeframe. If the frequency of occurrence of a voice fingerprint exceeds a threshold call quantity within the analyzed timeframe, the voice fingerprint is characterized as being associated with a robocaller."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detecting robocalls using biometric voice fingerprints","description":"The disclosed system and method detect robocalls using biometric voice fingerprints.
