Rendering visual components on applications in response to voice commands

A method of rendering visual components on applications, comprising:

• maintaining, by a data processing system having one or more processors, a plurality of action-inventories for a plurality of applications, at least one of the plurality of action-inventories indicating to render a user interface component for one of the plurality of applications in executing an action;
• receiving, by the data processing system, a data packet comprising an input audio signal detected by a sensor of a client device, the client device displaying a graphical user interface of a first application in a foreground process on the client device;
• parsing, by the data processing system, the input audio signal of the data packet to identify a request;
• selecting, by the data processing system, from the plurality of action-inventories, an action-inventory that executes the action corresponding to the request by a second application of the plurality of applications, the second application installed on the client device and not the foreground process;
• generating, by the data processing system, an action data structure in accordance with the action-inventory;
• providing, by the data processing system, the action data structure to the second application to cause the second application to parse the action data structure and execute the action to generate an output;
• determining, by the data processing system, that the output of the second application from execution of the action is authorized to be presented with the graphical user interface of the first application based on an authorization policy of the second application;
• identifying, by the data processing system, the user interface component of the second application for the action-inventory selected from the plurality of action-inventories, responsive to the determination the output of the second application is authorized to be presented with the first application;
• and
• displaying, by the data processing system, on the client device, the user interface component including the output from the second application with the graphical user interface of the first application authorized to be presented with the second application.
