Abstract
Systems and methods for detecting and tracking conversations of interest in crowded areas. The system includes a plurality of body worn portable public safety communication devices, each including a plurality of microphones and an electronic processor. The electronic processor is configured to generate, using the plurality of microphones, a plurality of beams and scan in parallel, using the plurality of beams, a plurality of simultaneous audio conversations. The electronic processor is configured to identify and isolate a plurality of conversations of interest from among the audio conversations based on predetermined characteristics indicative of a potential threat. The electronic processor is configured to determine that at least two of the plurality of conversations of interest are potentially linked to a single potential threat, compile them for playback or transcription, and generate an alert indicating the availability of the linked conversations of interest.
