In one embodiment, history-based key phrase suggestions are provided for voice control of a home automation system. A host controller builds a history database that maintains a history of events, each event indicating one or more services activated, one or more scenes activated or one or more types of media content presented by the home automation system. A predictions process on the host controller selects a subset of the events of the history database based on a present condition of the home automation system to produce a predication dataset. A grammar process on a remote control or mobile device selects one or more intentions from a list used by a voice recognition engine, based on the prediction dataset. Each intention includes a key phrase paired with an action. A voice user interface (UI) process suggests key phrases from the one or more selected intentions in a voice control UI on the remote control or mobile device.
