Multi-resolution audio activity tracker based on acoustic scene recognition

Abstract

A method and apparatus for recognizing an activity of a monitored individual in an environment are described including receiving a first acoustic signal, performing audio feature extraction on the first acoustic signal in a first temporal window, classifying the first acoustic signal by determining a location of the monitored individual in the environment based on the extracted features of the first acoustic signal in the first temporal window, receiving a second audio signal, performing audio feature extraction of the second acoustic signal in a second temporal window and classifying the second acoustic signal by determining an activity of the monitored individual in the location in the environment based on the extracted features of the second acoustic signal in the second temporal window.

Dependencies are inferred from the claim text.
