This disclosure describes techniques to augment the built-in grammar of a general-purpose voice-activated virtual assistant with custom commands and actions that are specific to a particular make and model of a device such as an in-vehicle system. The techniques enable the virtual assistant to service implicit commands that make no reference to vehicular make by providing custom, make-specific responses. A single, consistent grammar enables the general-purpose virtual assistant to handle device-specific commands without the user having to provide a query that includes a device-specific invocation phrase.
