Abstract: Systems and methods for managing multiple voice assistants are disclosed. Audio input is received via one or more microphones of a playback device. A first activation word is detected in the audio input via the playback device. After detecting the first activation word, the playback device transmits a voice utterance of the audio input to a first voice assistant service (VAS). The playback device receives, from the first VAS, first content to be played back via the playback device. The playback device also receives, from a second VAS, second content to be played back via the playback device. The playback device plays back the first content while suppressing the second content. Such suppression can include delaying or canceling playback of the second content.

Abstract: While operating in a first mode, a computing device transmits, to playback devices of a synchrony group, (i) media content and (ii) respective playback timing information for synchronous playback of the media content. After a first playback device with a different capability than at least one other playback device of the synchrony group has joined the synchrony group, the computing device begins to operate in a second mode for causing one or more of the playback devices of the synchrony group to modify playback of the media content based on a respective playback device capability. While operating in the second mode, the computing device (i) determines a modified sample rate for the first playback device to maintain synchrony of playback of the media content between the playback devices of the synchrony group, and (ii) causes the first playback device to play back the media content at the modified sample rate.

Abstract: In one aspect, a user's intent can be inferred based on voice analysis during a communications session, and prompts can be presented, or other actions taken, at least partly in response to the inferred intent. For example, a network microphone device (NMD) having one or more microphones can capture voice input and transmit the voice input to remote computing device(s) for a communication session (e.g., a videoconference). The NMD can analyze the voice input to detect one or more utterances. Based on the utterance(s), the NMD can cause a user prompt to be displayed via a display device communicatively coupled to the NMD. The particular prompt can depend at least in part on one or more context parameters associated with the communication session (e.g., a microphone state of one or more users, a screen share state of one or more users, or a recording status of the session, etc.).

Abstract: An implementation of portable playback device power management involves launching a power coordinator background process, the power coordinator background process having multiple client programs and establishing respective inter-process communication (IPC) mechanisms between the multiple client programs and the power coordinator background process. The implementation further involves receiving, via the established IPC mechanisms from the multiple client programs, messages indicating that the respective client program is ready to suspend, and determining that each client program of the multiple client programs is ready to suspend. The implementation further includes sending instructions to the operating system to kernel suspend. While in kernel suspend, the playback device detects a particular trigger to kernel resume and in response, performs a kernel resume.

Abstract: Examples described herein involve selecting a group coordinator device for a zone group. An example implementation includes: receiving an instruction to form a zone group comprising the first media device and the second media device; comparing a first one or more communication parameters corresponding to a network connection of the first media device to a second one or more communication parameters corresponding to a network connection of the second media device; identifying the first media device as a group coordinator of the zone group based on at least the indication that the first media device communicates with the router over the first communication frequency band; and configuring the first media device to provide data indicating audio content and audio content playback timing information to the second media device to facilitate synchronous playback of the audio content as the group coordinator of the zone group.

Abstract: A control device receives one or more first user inputs associating a particular playback mode with one or more playback devices and one or more user-defined acoustic parameters for particular media content that is associated with the particular playback mode. The control device associates a particular trigger condition with the particular playback mode. The particular trigger condition comprises a condition that causes the particular playback mode to be executed. The control device receives one or more second user inputs to activate a particular routine that is associated with the particular playback mode. After receiving the one or more second user inputs, the control device transmits a message that causes the one or more playback devices to play back the particular media content according to the one or more user-defined acoustic parameters.

Abstract: Turntable control systems are disclosed. A playback device can include an analog audio source component such as a turntable. The playback device is configured to cause playback of first audio based on analog audio signals generated by the analog audio source component. Based on an indication that analog audio signals are no longer being generated, the playback device requests, via a network interface, audio content from one or more remote computing devices. The request can include identifying related content based on the first audio. The playback device receives, via the network interface, second audio content from, and causes playback of second audio based on the second audio content.

Abstract: Example techniques facilitate calibration of a playback device. An example implementation involves a computing device capturing, via a microphone, data representing multiple iterations of a calibration sound as played by a playback device. The computing device identifies multiple sections within the captured data. Two or more sections represent respective iterations of the calibration sound as played by the playback device. Based on the multiple identified sections, the computing device determines a frequency response of the playback device, the frequency response of the playback device representing audio output by the playback device and acoustic characteristics of an environment around the playback device. Based on the frequency response of the playback device and a target frequency response, the computing device determines one or more parameters of an audio processing algorithm and sends, to the playback device, the one or more parameters of the audio processing algorithm.
