Abstract: A communication system actively monitors a conversation between users in an environment. Once a threshold condition occurs (e.g., client device within a threshold distance of a room where the conversation is occurring, the user enters a chatroom via the client device), the client device receives a summary from the communication system. The communication system may customize the summary in accordance with user preferences. User preferences may include level of detail in summary or time range associated with summary. The client device then presents the summary to the user. The summary may be audio or text. In some embodiments, the summary may be historical audio that is overlaid over current audio at faster speed and higher volume, and stops once the historical audio reaches real time.

Abstract: A method of tracking sound sources in an environment by monitoring the local area with a primary sensor system comprising a microphone array. The location of sound sources in the local area are tracked using the monitored sound. If an ambiguity is determined in the tracked location of the sound source, a secondary sensor system is activated. The secondary sensor system has a larger power draw than the primary sensor system. The secondary sensor system determines the updated location of the sound source. The tracked location of the sound sources is updated to be the updated location. Once the location is updated, the secondary sensor system is deactivated.

Abstract: A method to combine contact and acoustic microphones in a headset for voice wake and voice processing in immersive reality applications is provided. The method includes receiving, from a contact microphone, a first acoustic signal, determining a fidelity and a quality of the first acoustic signal, receiving, from an acoustic microphone, a second acoustic signal, and when the fidelity and quality of the first acoustic signal exceeds a pre-selected threshold, combining the first acoustic signal and the second acoustic signal to provide an enhanced acoustic signal to a smart glass user. A non-transitory, computer-readable medium storing instructions to cause a headset to perform the above method, and the headset, are also provided.

Abstract: A system controls the audio focus for a user in a virtual conference call. The system retrieves sound parameters associated with participants in the virtual conference call with the user from a user profile of the user. The sound parameters define volume adjustments to be applied to audio data received from the participants for generating an audio mix customized to the user. The system receives the audio data from client devices of the participants, and for each of the participants, adjusts the audio data of the participant using the associated sound parameter of the participant. The system adds the adjusted audio data of the participants to the audio mix for the user and provides the audio mix to a client device of the user.

Abstract: Determination of a set of acoustic parameters for a headset is presented herein. The set of acoustic parameters can be determined based on a virtual model of physical locations stored at a mapping server. The virtual model describes a plurality of spaces and acoustic properties of those spaces, wherein the location in the virtual model corresponds to a physical location of the headset. A location in the virtual model for the headset is determined based on information describing at least a portion of the local area received from the headset. The set of acoustic parameters associated with the physical location of the headset is determined based in part on the determined location in the virtual model and any acoustic parameters associated with the determined location. The headset presents audio content using the set of acoustic parameters received from the mapping server.

Abstract: The disclosed computer-implemented method may include receiving, from a third party, a portion of data or computer-executable logic that is part of a specified model. Each model may include various portions of independently verifiable computer-executable logic. The method may further include receiving data at a processing engine. The processing engine may be configured to apply the specified model to the received data. The method may then execute the specified model at the processing engine to modify the received data and send the modified data to an application that is configured to process the modified data. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A method for audio beam steering, tracking, and audio effects for an immersive reality application is provided. The method includes receiving, from an immersive reality application, a first audio waveform from a first acoustic source to provide to a user of a headset, identifying a perceived direction for the first acoustic source relative to the headset based on a location of the first acoustic source, and providing, to a first speaker in a client device, an audio signal including the first audio waveform, wherein the audio signal includes a time delay and an amplitude of the first audio waveform based on the perceived direction. A non-transitory, computer-readable medium storing instructions which, when executed by a processor, cause a system to perform the above method, and the system, are also provided.

Abstract: An electronic system is described that is responsive to non-verbal commands. The system may include a display component for presenting visual content to a user and an audio system, such as an in-ear or over-the-ear speaker system. The speaker system may be equipped with a bone conduction sensor or in-ear microphone that generates data associated with vibrations of a facial region of the user. The system may use the data to detect non-verbal command in the form of grunts, hums, coughs, tongue clicks, and the like. The system may perform various predetermined operations based on the detected vibrations.

Abstract: An audio system presents enhanced audio content to a user of a headset. The audio system detects sounds from the local area, at least a portion of which originate from a human sound source. The audio system obtains a voice profile of an identifies human sound source that generates at least the portion of the detected sounds. Based in part on the voice profile, the audio system enhances the portion of the detected sounds that are generated by the human sound source to obtain enhanced audio. The audio system presents the enhanced audio to the user.

Abstract: The disclosed computer-implemented method may include applying, via a sound reproduction system, sound cancellation that reduces an amplitude of various sound signals. The method further includes identifying, among the sound signals, an external sound whose amplitude is to be reduced by the sound cancellation. The method then includes analyzing the identified external sound to determine whether the identified external sound is to be made audible to a user and, upon determining that the external sound is to be made audible to the user, the method includes modifying the sound cancellation so that the identified external sound is made audible to the user. Various other methods, systems, and computer-readable media are also disclosed.
