A method to be performed by a playback device forming part of a media playback system including a controller device, the playback device comprising at least one microphone configured to detect sound, the method comprising:

• receiving a message from the controller device indicative of a user interaction via a controller application on the controller device, wherein the user interaction does not relate to activating a voice input;
• responsive to the message, opening an input detection window for a given time period;
• while the input detection window is open:
• receiving an input sound data stream from the at least one microphone before the input detection window ends, wherein the input sound data stream represents sound detected by the at least one microphone;
• analyzing the input sound data stream for a plurality of keywords supported by the playback device;
• determining, based on the analysis, that the input sound data stream includes voice input data comprising a keyword from among the plurality of keywords supported by the playback device;
• and
• responsive to the determining that the input sound data stream includes voice input data comprising a keyword, causing a command corresponding to the keyword to be performed.

One or more tangible, non-transitory computer-readable media having instructions stored thereon that are executable by one or more processors to cause a playback device to perform operations, the playback device forming part of a media playback system including a controller device, the playback device comprising at least one microphone configured to detect sound, the operations comprising:

• receiving a message from the controller device indicative of a user interaction via a controller application on the controller device, wherein the user interaction does not relate to activating a voice input;
• responsive to the message, opening an input detection window for a given time period;
• while the input detection window is open:
• receiving an input sound data stream from the at least one microphone before the input detection window ends, wherein the input sound data stream represents sound detected by the at least one microphone;
• analyzing the input sound data stream for a plurality of keywords supported by the playback device;
• determining, based on the analysis, that the input sound data stream includes voice input data comprising a keyword from among the plurality of keywords supported by the playback device;
• and
• responsive to the determining that the input sound data stream includes voice input data comprising a keyword, causing a command corresponding to the keyword to be performed.
