1. A computer-implemented method comprising:
- turning on a command recognition functionality for a listening horizon based at least in part on a probability a user would desire to engage in dialog given a particular computational state, wherein turning on a command recognition functionality for a listening horizon comprises determining a length of the listening horizon; and
, turning off the command recognition functionality after the listening horizon has expired.

Abstract
Conversational dialog with a computer or other processor-based device without requiring push-to-talk functionality, wherein computer-implemented methods probabilistically determines a user desire to engage in a dialog, and/or the context of the desire. Based thereon the method either turns on a speech recognition functionality for a period of time referred to as a listening horizon, or facilitates the user'"'"'s desire. Upon the listening horizon expiring, the method turns off the speech recognition functionality.

10. A system for controlling portions of an application, comprising:
-
a listening component to receive user commands; and
an application component that invokes the listening component in order to process the user commands, the application component having one or more listening segments contained therein, the listening segments associated with a dynamically determined listening horizon having a beginning time and an ending time, wherein the listening segments invoke the listening component automatically based on a determined probability that a user will issue a command. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A system for receiving responses to a query, comprising:
-
means for determining a listening segment having a dynamically determined delay time;
means for automatically turning on the listening segment during at least one portion of a computer process in order to receive the user input based on a determined probability that a user will issue a command; and
means for turning off the listening segment after the delay time.
