Apparatus and associated methods relate to a web-enabled mobile device operating voice assistant manager software configured and programmed to receive a request for a web-enabled operation, construct a voice command configured to implement the operation using a device-level voice assistant, and provide a voice indication of the operation result when the voice assistant is activated with the constructed voice command. In an illustrative example, the requested operation may be user designated in a web-enabled device visual interface. The operation may be an action, including, for example, user actions recorded from the visual interface, including text selection, form input, taps, or clicks, permitting construction of a voice command configured to implement the actions. In some examples, the operation may be a data retrieval operation providing a result vocalized to the user through the web-enabled device. Various examples may advantageously provide improved interoperability and enhanced ease of access between users, the user's web-enabled devices, software applications operating on the user's web-enabled devices, and various diverse device-level voice assistant implementations.
