Abstract
A system, computer-readable medium, and method for automatically determining a topic of a conversation and responding to the topic determination are provided. In the method, an active topic is defined as a first topic in response to execution of an application. The first topic includes first text defining a plurality of phrases, a probability of occurrence associated with each of the plurality of phrases, and a response associated with each of the plurality of phrases. Speech text recognized from a recorded audio signal is received.
