US Patent 10496363 Voice user interface for data access control

A voice user interface (VUI) may be deployed for accessing data that are stored in databases of a telecommunications network. A voice command received at a voice interface device connected to a telecommunications network may be converted into a persistent data representation via a speech interpretation engine. The persistent data representation is sent to an intent mapping service that maps persistent data representations to intermediate command representations. In turn, a command interpreter of the telecommunications network may receive the intermediate command representation from the intent mapping service. The command interpreter may translate the intermediate command representation into a database function command via a command interpreter of the telecommunications network. The database function command may be executed on data stored in a database of the telecommunications network via a database interface to generate at a synthesized speech output presented by the voice interface device or a visual output presented by a display device.
