Abstract
Methods, apparatus, systems and articles of manufacture to monitor tasks performed in an environment of interest are disclosed. One such apparatus is a task monitor that includes a signature comparator to compare a first signature to a second signature. The first signature is generated based on first audio collected in an environment of interest and the second signature is generated based on second audio collected during performance of a task in the environment of interest. The task monitor also includes an object identifier to identify an object corresponding to a location determined based on an angle of arrival of the first audio at a sensor. A task identifier is to identify the task as a cause of the first audio when the signature comparator determines the first signature matches the second signature and the object identifier identifies the object as a same object used to perform the task.
