Abstract: Example techniques involve a control hierarchy for a “smart” home having smart appliances and related devices, such as wireless illumination devices, home-automation devices (e.g., thermostats, door locks, etc.), and audio playback devices, among others. An example home includes various rooms in which smart devices might be located. Under the example control hierarchy described herein and referred to as “home graph,” a name of a room (e.g., “Kitchen”) may represent a smart device (or smart devices) within that room. In other words, from the perspective of a user, the smart devices within a room are that room. This hierarchy permits a user to refer to a smart device within a given room by way of the name of the room when controlling smart devices within the home using a voice user interface (VUI) or graphical user interface (GUI).

Abstract: In some embodiments, a method comprises receiving a first signal indicative of a current emotional state of one or more users, receiving a second signal corresponding to a desired emotional state, and causing a playback device to play back generative audio. The method can further comprise, after receiving the first signal and the second signal, adjusting one or more audio characteristics of the generative audio to provide at least (i) a first portion of media content having a first parameter corresponding to the current emotional state, (ii) a second portion of media content having a second parameter different than the first parameter, and (iii) an nth portion of media content having an nth parameter corresponding to the desired emotional state.

Abstract: Examples involve a control device using a social networking service to facilitate registration of a streaming media service with a media playback system. An example implementation receives (i) data indicating login credentials for a given account of a social networking service, and (ii) input data to configure streaming media services with a media playback system. Based on receiving the input data to configure the media playback system, the implementation queries the social networking service for streaming media services associated with the given account, and in response to the query, receives data indicating a first streaming media service associated with the given account. The implementation configures the media playback system to playback audio content from the first streaming media service that is associated with the given account and causes the media playback system to playback audio content from the first streaming media service.

Abstract: Disclosed herein are example techniques to support multiple voice assistant services. An example implementation may involve a playback device capturing audio from the one or more microphones into one or more buffers as a sound data stream monitoring the sound data stream for a wake word associated with a specific voice assistant service and monitoring the sound data stream for a wake word associated with the media playback system. The playback device generates a second wake-word event corresponding to a voice input when sound data matching the wake word associated with the media playback system in a portion of the sound data stream is detected. The playback device determines that the voice input includes sound data matching one or more playback commands and sends sound data representing the voice input to a voice assistant associated with the media playback system for processing of the second voice input.

Abstract: Example techniques involve a calibration state variable. An example implementation receives, via a network interface, an indication that the first playback device is calibrated. Based on receiving the indication that the first playback device is calibrated, the example implementation updates a calibration state variable to indicate that the first playback device is calibrated, wherein the calibration state variable is stored in the data storage. The example implementation sends, via the network interface, an indication of the updated calibration state variable to a second device.

Abstract: Example techniques may involve tuning a music discovery dial. An implementation may include displaying, on the touch-sensitive circular graphical display, a circular graphical user interface including multiple wedge-shaped selectable regions arranged around the circumference of the circular graphical user interface, each wedge-shaped selectable region corresponding to a respective streaming audio channel. The implementation may include detecting a touch input in a circular motion to the touch-sensitive circular graphical display and causing a paired playback device to play back an audio content snippet corresponding to each selectable regions that the touch input enters. The implementation may further include switching the playback device from playing back a given pre-cached audio content snippet to playing back the full audio track from one or more servers of a streaming audio service.

Abstract: Examples described herein relate to transitioning a playback session between portable playback devices such as “smart” headphones, earbuds, and handheld speakers with playback devices of a zone-based media playback system. Exemplary techniques facilitate continuity of playback when transitioning between locations (e.g., from at home to on-the-go or vice versa) or between listening paradigms (e.g., personal or out-loud playback of audio content). An example implementation includes detecting a swap trigger, determining the source playback device(s) and target playback device(s), and performing a playback session swap between the source playback device(s) and target playback device(s).

Abstract: Example techniques relate to calibration interfaces that facilitate calibration of a playback device. An example implementation may involve outputting a sequence of prompts to guide calibration of a playback device during a calibration sequence comprising (i) a spatial calibration component and (ii) a spectral calibration component. Outputting the sequence of prompts includes outputting one or more first audio prompts representing a guide to perform the spatial calibration component of the calibration sequence. The spatial calibration component involves calibration of the playback device for a particular location within an environment. Outputting the sequence of prompts also includes outputting one or more first second prompts representing a guide to perform the spectral calibration component of the calibration sequence. The spectral calibration component involves calibration of the playback device for the environment.

Abstract: Generative media content (e.g., generative audio) can be played back across multiple playback devices concurrently. A coordinator device can receive a multi-channel stream of media content, with at least some channels comprising generative media content. The coordinator device transmits each of the channels to a plurality of playback devices. A first playback device plays back a first subset of the channels according to first playback responsibilities and a second playback device plays back a second subset of the channels according to second playback responsibilities. The first and/or second playback responsibilities can be dynamically modified over time, for example in response to one or more input parameters.

Abstract: Example techniques involve a calibration state variable. An example implementation receives, via a network interface, an indication that the first playback device is calibrated. Based on receiving the indication that the first playback device is calibrated, the example implementation updates a calibration state variable to indicate that the first playback device is calibrated, wherein the calibration state variable is stored in the data storage. The example implementation sends, via the network interface, an indication of the updated calibration state variable to a second device.

Abstract: Examples disclosed herein relate to playback device calibration. A calibration state variable may represent a calibration state of a playback device. A control device may display an indications of the calibration state. For instance, in a first instance, the control device may display an indication that a first playback device is in an uncalibrated state. Further, in a second instance, the control device may display an indication that the first playback device is in an calibrated state, perhaps after instructing the first playback device to initiate calibration.
