Abstract: Techniques for voice-based interactions are described. In an example, a device presents a user interface on a display. The device starts an operational mode of the device. The operational mode restricts voice-based interactions with the user interface to a set of commands. The set of commands is defined in a language model that is stored on the device. Further, the device receives, at a microphone of the device, audio data corresponding to a natural language utterance and generates, from the audio data, text data that corresponds to the natural language utterance. The device determines, based at least in part on the language model, that semantics of the text data correspond to a command from the set of commands and presents, on the display, an outcome of performing the command.
