1. A computer-implemented method comprising:
- determining that a user desires to engage in a dialog based at least upon inferring a probability that the user desires an automated service;
upon determining that the user desires to engage in a dialog, turning on a speech recognition functionality for a listening horizon, wherein the length of the listening horizon is determined as a function of at least an inferred probability that the user desires automated service; and
,turning off the speech 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. In one embodiment, a computer-implemented method first determines that a user desires to engage in a dialog. Based thereon the method turns on a speech recognition functionality for a period of time referred to as a listening horizon. Upon the listening horizon expiring, the method turns off the speech recognition functionality.

15. A computer-implemented method comprising:
-
determining that a user desires to engage in a dialog based at least upon inferring a probability that the user desires an automated assistant; upon determining that the user desires to engage in a dialog, engaging the user with a question; displaying an automated assistant asking the question; turning on a speech recognition functionality for a listening horizon; during the listening horizon, detecting an utterance from the user; determining a confidence level of the utterance, wherein the automated assistant indicates understanding of the utterance if the confidence level is above a predetermined threshold; and
,no later than after expiration of the listening horizon, removing the automated assistant; turning off the speech recognition functionality. - View Dependent Claims (16, 17)

18. A machine-readable medium having instructions stored thereon for execution by a processor to cause performance of a method comprising:
-
determining that a user desires to engage in a dialog based at least upon inferring a probability that the user desires an automated agent; upon determining that the user desires to engage in a dialog, turning on a speech recognition functionality for a listening horizon, wherein the length of the listening horizon is determined as a function of at least an inferred probability that the user desires automated service; and
,turning off the speech recognition functionality after the listening horizon has expired.
