  • Patent number: 10848201
    Abstract: A cloud based echo canceller is set forth for recreating an estimate of a lost packet or data at a server without requiring redundant data over the network or freezing operation of the echo canceller. In an exemplary embodiment, the echo cancelling function is not located in a single device, but is shared between the end-point and a cloud service, where the function of the end-point is to provide a time synchronized copy of the signal from the end-point loudspeaker and the signal received by the end-point microphone. Consequently, the high CPU intensive operations can be offloaded to a server such as a cloud server. In addition, several users can share the echo canceller, thereby reducing the cost of the overall function. According to an additional aspect, a further synchronization block is provided, in the form of a packet estimator, to compensate for packet or data loss in the send direction.

  • Patent number: 10848887
    Abstract: Detection of a blocked microphone involves receiving microphone signals from a plurality of microphones. A plurality of signal feature measures are derived from the microphone signals. The signal feature measures are normalised. The normalised signal feature measures are variably weighted in response to detected environmental conditions in the microphone signals. The variably weighted normalised signal feature measures are combined to produce an output indication of whether a microphone is blocked.

  • Patent number: 10841703
    Abstract: Embodiments of the present disclosure relate to methods and apparatus for peripheral device discovery, the detection of orientation of a connector having multiple degrees of rotational symmetry, and the provision of appropriate signal paths between a host device and a peripheral device. Some embodiments provide a characteristic impedance within the peripheral device that is coupled between rotationally symmetric contacts of the connector and thus enables detection of the connector orientation. The value of the characteristic impedance may be used in some embodiments to determine the type or model of peripheral device. Some embodiments are concerned with the enablement of appropriate signal paths to a peripheral device having a transducer (e.g. a loudspeaker) coupled only to rotationally symmetric contacts of the connector, such as headphones implemented in a “balanced” configuration.

  • Patent number: 10834256
    Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for delivering content to a client device placed on hold. A communication system establishes a communication session between a client device placed on hold and a content delivery service, during which the content delivery service streams content to the client device via the established communication session. The communication session between the client device that initiated the hold and the client devices that are placed on hold is terminated, thereby allowing the client device that initiated the hold to establish communication sessions other client devices if so desired. A unique identifier generated to reference the hold is provided to the client device that initiated the hold, which the client device may then use to reference the hold to execute a desired action, such as ending the hold, terminating the communication session, retrieving a status of the hold, etc.
