Patent number: 11689858Abstract: Example techniques relate to device spaces and default designations in a media playback system. A device space may create an association between a networked microphone device and one or more playback devices such that certain voice commands (e.g., playback commands) received by the networked microphone device are used to control the one or more playback devices (unless otherwise designated in the voice command). Furthermore, in bonded pairs and bonded groups of playback devices that include at least one NMD, certain playback devices within the bonded pair or group may be designated as default so as to avoid multiple responses to a voice input.Type: GrantFiled: May 23, 2022Date of Patent: June 27, 2023Assignee: Sonos, Inc.Inventors: Sein Woo, Andrew Lindley, Ryan Myers
