Abstract: Examples described herein include distributed computing systems having a system traffic analyzer. The system traffic analyzer may receive sampled packets sent to a network from a number virtual machines hosted by computing nodes in the distributed computing system. The packets may be sampled, for example, by network flow monitors in hypervisors of the computing nodes. The system traffic analyzer may request co-location of virtual machines having greater than a threshold amount of traffic between them. The request for co-location may result in the requested virtual machines being hosted on a same computing node, which may in some examples conserve network bandwidth.

Abstract: An audio capture device that incorporates a beamformer and beam-specific trigger word detection. Audio data from each beam is processed by a low power trigger word detector, such as a neural network or other trained model to detect if audio data (such as an audio frame or feature vector corresponding thereto) likely includes part of a trigger word. The beam that either most strongly represents a trigger word portion or represents a trigger word portion most early in time may be selected for further processing such as speech processing or confirmation by a more robust power intensive trigger word detector.

Abstract: A wearable computer is configured to use beamforming techniques to isolate a user's speech from extraneous audio signals occurring within a physical environment. A microphone array of the wearable computer may generate audio signal data from an utterance from a user's mouth. A motion sensor(s) of the wearable computer may generate motion data from movement of the wearable computer. This motion data may be used to determine a direction vector pointing from the wearable computer to the user's mouth, and a beampattern may be defined that has a beampattern direction in substantial alignment with the determined direction vector to focus the microphone array on the user's mouth for speech isolation.

Abstract: A beamformer system that can isolate a desired portion of an audio signal resulting from a microphone array. A combination of beamformers is used to dampen undesired noise, whether diffuse or coherent. A fixed beamformer is used to dampen diffuse noise while an adaptive beamformer is used to cancel directional coherent noise. The adaptive beamformer isolates and weights audio from various directions. The weights may vary depending on the isolated desired audio signal, dynamically adjusting the step-size adjustments to the weights.

Abstract: An acoustic interference cancellation system that combines acoustic echo cancellation and an adaptive beamformer to cancel acoustic interference from an audio output. The system uses a fixed beamformer to generate a target signal in a look direction and an adaptive beamformer to generate noise reference signals corresponding to non-look directions. The noise reference signals are used to estimate acoustic noise using an acoustic interference canceller (AIC), while reference signals associated with loudspeakers are used to estimate an acoustic echo using a multi-channel acoustic echo canceller (MC-AEC). The system cancels the acoustic echo and the acoustic noise simultaneously by adding the estimate of the acoustic noise and the estimate of the acoustic echo to generate an interference reference signal and cancelling the interference reference signal from the target signal. The system jointly updates adaptive filters for the AIC and the MC-AEC logic to improve a robustness of the system.
