Abstract
A central authority receives a wake word associated with a service request from a user of a client device. The central authority sends the received wake word to a set of wake word engines. The central authority receives a signal from a selected wake word engine indicating that an assistant associated with the selected wake word engine has been selected by the user based on the received wake word. The central authority transmits a signal blocking the remainder of the wake word engines from receiving additional wake words, and sends the service request to the assistant. Responsive to the assistant receiving the service request, the central authority transmits a signal unblocking the remainder of the wake word engines from receiving wake words.
