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.

Abstract: Methods and systems for processing audio information captured by an interactive virtual assistant (IVA). An example method includes: converting sound received by a microphone into electrical signals; generating voiceprints corresponding to voices represented in the electrical signals; distinguishing signals representing background speech and signals representing voice commands directed at the IVA; and based on various signals representing background speech and voice commands, labeling each of the voiceprints with a tag selected from the group consisting of an IVA interactor occupant tag, an IVA non-interactor occupant tag, and a non-occupant tag. The method also includes transmitting, in response to a trigger event, a message with at least one of an estimated number of occupants in a geofenced area corresponding to the IVA and an alert reporting an indication of unlawful activity thereat.
