Title: PREVENTING OF AUDIO ATTACKS
Abstract:
In some implementations, a method includes receiving, at a processing module of a device, output audio data that represents audio output by the device, receiving, by the processing module, input audio data that represents audio detected by a microphone, determining, by the processing module, that the output audio data includes a representation of a hotword, wherein the hotword is a word or phrase previously designated to precede a voice command, and, based on determining that the output audio data includes the representation of the hotword, blocking, by the processing module, use of the input audio data to initiate a command.
