A voice user interface (VUI) may be deployed for controlling network components and devices 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 an action command for performing a task with respect to network components or devices of the telecommunications network. The action command may be executed via a controller interface of the telecommunications network with respect to the network components or the devices of the telecommunication network.
