The disclosed embodiments include computerized methods, systems, and devices, including computer programs encoded on a computer storage medium, for integrating voice-based interaction and control into a native graphical user interface (GUI) of an executed application. For example, a communications device may receive audio data corresponding to an utterance spoken by a user, and may obtain structured data representative of the received audio data. The communications device may provide structured data to the executed application through a programmatic interface, and the executed application may perform the one or more operations in accordance with the structured data. The communications device may generate data indicative of an output of the one or more operations performed by the executed application, and may present at least a portion of the generated output data to a user through a corresponding interface.
