1. A computer-implemented system that responds to human communications, comprising: a recognition component that dynamically monitors human communications for an apparent intent related to a task discussed by a user during a communication session with a human second party; a task component that receives, at least in part, an apparent intent from the recognition component and associates it with a task to form a candidate task for prompting a user; and a computer readable storage medium comprising data structures and sets of codes for causing a computer to execute the recognition and task components.
