Abstract
A speech-processing system may provide access to one or more virtual assistants via a voice-controlled device. The system may be activated by detecting a wakeword in speech received by a microphone of the device. The system may process the speech and provide a response in the form of synthetic speech. When a speaker of the device synthetic emits the speech, the microphone may detect some or all of the speech. If the synthetic speech includes a wakeword or words or phrases similar to the wakeword, a wakeword detection component of the device may detect the wakeword and activate an assistant, resulting in a self-wake or cross-wake. Self- or cross-wake may interrupt an action or response currently in progress, which may frustrate the user and result in a poor user experience. This disclosure thus proposes systems and methods for preventing cross-wake and self-wake in a voice-controlled device.
