  • Publication number: 20240282301
    Abstract: An electronic device may capture a voice command from a user. The electronic device may store contextual information about the state of the electronic device when the voice command is received. The electronic device may transmit the voice command and the contextual information to computing equipment such as a desktop computer or a remote server. The computing equipment may perform a speech recognition operation on the voice command and may process the contextual information. The computing equipment May respond to the voice command. The computing equipment may also transmit information to the electronic device that allows the electronic device to respond to the voice command.

  • Publication number: 20240161721
    Abstract: Systems, devices, and methods for motion-based output of audio content are provided. The motion-based output of audio content may include synchronizing a tempo and a phase of audio content being output with a cadence and a phase of a cyclic movement of a user of an electronic device. The motion-based output can be performed by a system-level process such that synchronizations to motion cadence and phase can be provided for local audio content and/or audio content from any of various content streaming sources. The motion-based output can also account for algorithmic and/or transmission latencies, to output beats of the audio content in sync with user footfalls, including in implementations in which wireless headphones or earbuds are used. Tempo and phase matching can also be provided across a delay or interval in which there is no output of audio content, such as during the gap between adjacent songs in a playlist.

  • Patent number: 11979734
    Abstract: A system and method is described for determining whether a loudspeaker device has relocated, tilted, rotated, or changed environment such that one or more parameters for driving the loudspeaker may be modified and/or a complete reconfiguration of the loudspeaker system may be performed. In one embodiment, the system may include a set of sensors. The sensors provide readings that are analyzed to determine 1) whether the loudspeaker has moved since a previous analysis and/or 2) a distance of movement and/or a degree change in orientation of the loudspeaker since the previous analysis. Upon determining the level of movement is below a threshold value, the system adjusts previous parameters used to drive one or more of the loudspeakers. By adjusting previous parameters instead of performing a complete recalibration, the system provides a more efficient technique for ensuring that the loudspeakers continue to produce accurate sound for the listener.

  • Patent number: 11736862
    Abstract: An audio system and method of using the audio system to augment spatial audio rendition is described. The audio system can include a device to receive user inputs designating positions on an augmented reality view of a listening environment. Sound source icons can be presented in the augmented reality view at the designated positions. The sound source icons can visually represent sound sources at locations in the listening environment that correspond to, but are different than, the positions. One or more processors of the audio system can apply head-related transfer functions, which correspond to the locations in the listening environment, to audio input signals to generate binaural audio signals. The audio system can include a headset that uses the binaural audio signals to render spatialized audio localizing sounds to the locations in the listening environment. Other aspects are also described and claimed.

  • Patent number: 11715483
    Abstract: Aspects of the subject technology relate to a device including a microphone, a filter and a processor. The filter receives an audio signal including ambient noise and a voice of a user of the device from the microphone. At least a portion of ambient noise is filtered from the audio signal. The processor determines a level of the ambient noise in the received audio signal and dynamically adjusts a gain applied to the filtered audio signal based on the level of the ambient noise.

  • Patent number: 11683632
    Abstract: An automatic speech recognition (ASR) triggering system, and a method of providing an ASR trigger signal, is described. The ASR triggering system can include a microphone to generate an acoustic signal representing an acoustic vibration and an accelerometer worn in an ear canal of a user to generate a non-acoustic signal representing a bone conduction vibration. A processor of the ASR triggering system can receive an acoustic trigger signal based on the acoustic signal and a non-acoustic trigger signal based on the non-acoustic signal, and combine the trigger signals to gate an ASR trigger signal. For example, the ASR trigger signal may be provided to an ASR server only when the trigger signals are simultaneously asserted. Other embodiments are also described and claimed.

  • Publication number: 20220020387
    Abstract: Implementations of the subject technology provide systems and methods for determining whether to interrupt a user of an audio device that is operating in a noise-cancelling mode of operation. For example, the user may desire to be interrupted by one or more pre-designated contacts that are identified at an associated electronic device as interrupt-authorized contacts, or by a person who speaks a designated keyword to the user.

  • Patent number: 10825480
    Abstract: A method for automatically producing a video and audio mix at a first portable electronic device. The method receives a request to capture video and audio, performs a network discovery process to find a second portable electronic device, and sends a message to the second device indicating when to start recording audio for a double system recording session. The method initiates the recording session, such that both devices record concurrently. In response to the first device stopping the recording of audio and sound, signaling the second device to stop recording for the identified recording session. In response to the first device receiving a first audio track from the second device that contains an audio signal recorded during the recording session, automatically generating a mix of video and audio, such that one of the audio signals from the first and second tracks is ducked relative to the other.

  • Patent number: 10764670
    Abstract: A system having a head-mounted display (HMD) mount and a mobile device, are described. A processor of the system can determine whether the mobile device is mounted on the HMD mount and handle an audio signal communicated from the mobile device to a wireless headphone based on whether the mobile device is mounted on the HMD mount. When the mobile device is not mounted on the HMD mount, the mobile device or the wireless headphone may operate in a first audio mode. When the mobile device is mounted on the HMD mount, the mobile device or the wireless headphone may operate in a second audio mode. The second audio mode can reduce audio signal latency between the mobile device and the wireless headphone and increase motion-to-sound quality. Other embodiments are also described and claimed.
