Abstract
An HVAC controller may be controlled in response to a natural language audio message that is not recognizable by the HVAC controller as a command, where the natural language audio message is translated into a command recognizable by the HVAC controller. Voice recognition software identifies a trigger phrase included in the natural language audio message and in response the HVAC controller performs an action. In response to identifying a trigger phrase at the HVAC controller, the HVAC controller may establish a single duplex connection with a remote server having a voice interaction module. An end user may then have a continuous dialog with the voice interaction module via the HVAC controller over the established single duplex connection. The voice interaction module may allow for an end user to interrupt the dialog at any time, as desired.
