1. A computer-implemented method, comprising:
receiving, at a device, first audio data corresponding to a first utterance;
determining the first audio data includes a first representation of a first wakeword corresponding to a first speech-processing system;
causing the first speech-processing system to perform processing with regard to the first utterance;
receiving, at the device, second audio data corresponding to a second utterance, wherein the second audio data includes a second representation of a second wakeword corresponding to a second speech-processing system and a third representation of the first wakeword, wherein the second representation appears in the second audio data prior to the third representation; and
based at least in part on the second representation appearing in the second audio data prior to the third representation, causing the second speech-processing system to perform processing with regard to the second utterance.
