A method on a mobile device for a wireless network is described. An audio input is monitored for a trigger phrase spoken by a user of the mobile device. A command phrase spoken by the user after the trigger phrase is buffered. The command phrase corresponds to a call command and a call parameter. A set of target contacts associated with the mobile device is selected based on respective voice validation scores and respective contact confidence scores. The respective voice validation scores are based on the call parameter. The respective contact confidence scores are based on a user context associated with the user. A call to a priority contact of the set of target contacts is automatically placed if the voice validation score of the priority contact meets a validation threshold and the contact confidence score of the priority contact meets a confidence threshold.

Method and device for audio input routing

A method on a mobile device for processing an audio input is described. A trigger for the audio input is received. At least one parameter is determined for an audio processor based on at least one input characteristic for the audio input. The audio input is routed to the audio processor with the at least one parameter.

A disclosed method of operation includes generating a first resolution geographic descriptor that identifies a first size geographic grid area. The first size geographic grid area includes a specific location identified by mobile device location data but does not identify the specific location. The method proceeds with adjusting the first resolution geographic descriptor to a second resolution geographic descriptor, by increasing or decreasing the resolution to correspondingly decrease or increase, respectively, the corresponding geographic grid area to a second size geographic grid area that includes the specific location. An information update is then sent to a server. The information update includes the second resolution geographic descriptor but does not provide the mobile device location data, in order to preserve the mobile device user's anonymity.

Method and apparatus for enforcing tiered geographical anonymity in a mobile device

Implementations relate to systems and methods for generating compensated speed values for a Doppler-enabled device. A portable wireless device can contain a GPS navigation engine () to capture position data () and Doppler speed data () from positioning satellites. The device can also generate position-based speed values from successive position readings and time intervals, to determine the current speed independently of the Doppler-based speed values. During degraded signal conditions, the Doppler-based speed values can drop to invalid levels. The device incorporates a combiner module () which compares the position-based and Doppler-based speed values and performs combination operations on those quantities to produce a compensated speed value (). By selecting the maximum or otherwise combining those values, extreme excursions in speed values are avoided and accuracy promoted.
