1. A method comprising:
identifying, at a client device, a wake word and a request in first audio data that is generated at the client device;
determining whether the first audio data is directed at a local security system by determining that the request identifies a local device that is locally connected to the local security system, and whether the request includes a command directed at the local device; and
in response to determining that the first audio data is directed at a server and not at the local security system, converting a text of the wake word and the request to second audio data, and providing the second audio data to the server.
