Abstract: A method for improving speech recognition by a speech recognition system includes obtaining a voice sample from a speaker; storing the voice sample of the speaker as a voice model in a voice model database; identifying an area from which sound matching the voice model for the speaker is coming; providing one or more audio signals corresponding to sound received from the identified area to the speech recognition system for processing.

Abstract: A method of enabling speech commands in an application includes identifying, by a computer processor, a user interaction element within a resource of the application; extracting, by the computer processor, text associated with the identified user interaction element; generating, by the computer processor, a voice command corresponding to the extracted text; and adding the generated voice command to a grammar associated with the application.

Abstract: Systems, methods, devices, and computer program products are described for using context-aware recommendation techniques to facilitate content discovery on a mobile device platform. In particular, the context-aware recommendation techniques evaluate both a current device context and a social context to generate application relevance scores for each of a number of applications downloaded to a mobile device. Application representations on a graphical user interface (GUI) of the mobile device are rearranged, resized, and/or otherwise affected according to their respective application relevance scores. In certain configurations, one or more applications are pinned, thereby altering (e.g., reducing or eliminating) how changes in their respective application relevance scores affect display of their respective application representations on the GUI of the mobile device.

Abstract: A targeted-content-message-related profile for use with wireless access terminals (W-ATs) may be generated by one or more usage-related rules on the W-AT itself. The usage generate rules may be used by the W-AT to generate a user profile, with the usage-related rule providing a dynamic property to the user profile. All or part of the user profile may then be used as a targeted-content-message-related profile for targeting content messages.

Abstract: Methods and systems for determining a suitability for a mobile client to display information are disclosed. A particular exemplary method includes generating a first value for a first targeted content message based on at least a first weighted sum of first user profile attributes, a user profile attribute being a numeric quantity relating to at least one of a preference and a demographic of a user of the mobile client, comparing the first value with a stored list of second values related to respective stored messages in a cache memory of the mobile client to produce a comparison result; and updating the cache memory based on the comparison result by storing the first targeted content message in the cache memory if the comparison result indicates a higher desirability of the first targeted content message over at least one stored message.

Abstract: Methods and systems for determining a suitability for a mobile client to display information are disclosed. A particular exemplary method includes maintaining on the mobile client a list of first attributes relating to message cache misses of a cache memory located on the mobile client, receiving on the mobile client a set of target attributes associated with a target message, performing on the mobile client one or more matching operations between the first attributes and the target attributes to produce a matching result, and storing the target message in a cache in the mobile client dependant upon the matching result.

Abstract: Methods and systems for determining a suitability for a mobile client to display information are disclosed. For example, a method for determining a suitability for a mobile client to receive a targeted content message includes generating user profile data by the mobile client, receiving a set of target profile data associated with the targeted content message, the set of target profile data being descriptive of the targeted content message, comparing the user profile data with the target set of profile data to produce a set of confidence-level data, a target set of profile data describing the content of a respective targeted-content message, and storing the targeted content message in the mobile client based upon the set of confidence-level data.

Abstract: A targeting-message profile may be obtained by a wireless access terminal (W-AT) by receiving a rule for establishing a user profile, synthesizing at least one profile attribute based on user behavior, and determining a need for further information based on the at least one profile attribute. Then, the W-AT may request the further information from an apparatus external to the W-AT, such as a server containing census information, receive the further information from the apparatus, and generate the profile based on the profile attributes and the further information.
