Aspects of the disclosure relate to voice activity detection (VAD) on wearable and other resource-constrained devices, to classify speech recorded by a microphone of the device as belonging to a wearer of the device versus another speech source. A computing device can include a microphone and an inertial measurement unit (IMU). The wearable device can use signals measured by the IMU for providing motion-tracking features, such as head tracking for augmented reality or virtual reality applications. Aspects of the disclosure provide for a device for leveraging existing data collected for these motion-tracking features for use in VAD. A device can pre-process data streamed from an IMU to use only signals predetermined to be indicative of whether or not a wearer of the device is speaking.

Speech detection using multiple acoustic sensors

Methods, systems, devices, and computer-readable storage media for activity detection of a user of a computing device, using multi-modal sensing. A device can be configured to receive sensor data corresponding to multiple modalities and process the sensor data to predict an activity performed by a user of a computing device. The device in response to the detected activity can perform a response action, such as muting or pausing audio playback from the computing device. Different modalities can be combined, such as body vibration data, air vibration data, and image data, which can be processed to distinguish user activity, e.g., speaking versus not speaking, to allow the computing device to perform the correct corresponding action.

Activity detection on devices with multi-modal sensing

To organize configuration parameters for rendering map features on digital maps, a data structure storing multiple nodes is generated. Respective sets of map feature attributes and configuration parameters are assigned to the nodes. The configuration parameters specify visual attributes for rendering map features. Indications of relationships between the nodes are generated, where at least several of the nodes include several child nodes. An indication of one or more map feature attributes to which a certain map feature belongs is received, and the data structure is traversed according to the indicated relationships between the nodes to generate a set of configuration parameters for rendering the map feature. Traversing the data structure includes comparing the indicated map feature attribute or map feature attributes to sets of map feature attributes at some of the nodes, such that the generated set of configuration parameters includes configuration parameters from at least two of the nodes.

Systems and methods for efficiently organizing map styling information

The subject matter of this specification can be implemented in, among other things, a computer-implemented method for accessing map tiles. The method includes receiving a first request from a computing device for a portion of a map. The portion of the map includes combined map tiles that are a combination of corresponding ones of first map tiles from a first type of map and second map tiles from a second type of map. The method further includes providing first tile version identifiers and second tile version identifiers to the computing device in response to receiving the first request. The method further includes providing instructions to the computing device for using the first tile version identifiers and the second tile version identifiers to request the combined map tiles.

Accessing map tiles

Systems and methods for applying one or more route-based modifications to a map are provided. In some aspects, a system includes a pathfinder module configured to determine a primary route from a beginning point to a destination point on the map. The pathfinder module is further configured to generate one or more primary modifications to the map based on the primary route. The system also includes a restyling module configured to apply the primary route and the one or more primary modifications to the map. The one or more primary modifications include at least one of a) adding a first object to the map that would otherwise be excluded from the map if the primary route is not applied to the map and b) excluding a second object from the map that would otherwise be added to the map if the primary route is not applied to the map.
