US Patent 10417385 Methods and systems for audio call detection

Systems and methods allow caregivers, central monitoring, and/or other persons to monitor whether a patient or another person has generated a call, such as an audio call. The systems and methods work by detecting audio within one or more audio detection zones, which are predefined areas surrounding the patient or other person to be monitored. The systems and methods detect when a command/keyword is spoken in the audio detection zone and generate an appropriate alert to an appropriate role.
