摘要
Disclosed in some examples, are methods, systems, and machine-readable mediums for preventing unintended activation of voice command processing of a voice activated device. A first audio signal may be an audio signal that is to be output to a speaker communicatively coupled to the computing device. A second audio signal may be input from a microphone or other audio capture device. Both audio signals are input to a keyword detector to check for the presence of activation keywords. If the activation keyword(s) are detected in the second audio signal but not the first audio signal the voice command processing of the device is activated as this is likely a command from the user and not feedback from the loudspeaker.
