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.

Abstract: In some implementations, a method is performed by computing devices, and includes receiving a first message indicating that an improper voice command has been detected by a first device, identifying a user account associated with the first device based on the first message, identifying a second device associated with the user account, and, in response to receiving the first message indicating that the voice command detected by the first device is improper, sending a second message to the second device, the second message indicating that the voice command should not be performed.
