摘要： Techniques are provided to improve identification of a person using speaker recognition. In one embodiment, a unique social graph may be associated with each of a plurality of defined contexts. The social graph may indicate speakers likely to be present in a particular context. Thus, an audio signal including a speech signal may be collected and processed. A context may be inferred, and a corresponding social graph may be identified. A set of potential speakers may be determined based on the social graph. The processed signal may then be compared to a restricted set of speech models, each speech model being associated with a potential speaker. By limiting the set of potential speakers, speakers may be more accurately identified.

摘要： Transmit power for an access point is controlled based on information received by the access point (106). For example, an access point may employ one or more algorithms that use messages received from nearby access terminals (102, 104) to maintain an acceptable tradeoff between providing an adequate coverage area for access point transmissions and mitigating interference that these transmissions cause at nearby access terminals (104). Here, the access point may employ a network listen-based algorithm upon initialization of the access terminal to provide preliminary transmit power control until sufficient information is collected for another transmit power control algorithm (e.g., an access terminal assisted algorithm). Also, the access point may employ an active access terminal protection scheme to mitigate interference the access point may otherwise cause to a nearby access terminal (104) that is in active communication with another access point (108).
摘要翻译：基于由接入点（106）接收的信息来控制接入点的发射功率。例如，接入点可以使用一个或多个算法，其使用从附近的接入终端（102,104）接收的消息来维持在为接入点传输提供足够的覆盖区域和减轻这些传输在附近接入造成的干扰之间的可接受的折中端子（104）。这里，接入点可以在接入终端初始化时采用基于网络侦听的算法，以提供初始的发射功率控制，直到为另一发射功率控制算法（例如，接入终端辅助算法）收集足够的信息。此外，接入点可以采用主动接入终端保护方案来减轻接入点可能导致与另一接入点（108）主动通信的附近接入终端（104）的干扰。

摘要： Transmissions by a first access point (e.g., a femto cell) are restricted upon detecting an access terminal in the vicinity of the first access point in the event the access terminal is communicating with a second access point (e.g., a macro cell). Upon detection of such an access terminal, the access terminal restricts transmission (e.g., beacon transmission) on a downlink carrier frequency on which the access terminal is actively receiving information from the second access point. This restriction of transmission by the access point may involve, for example, temporarily reducing transmit power, reducing the periodicity of transmission, or ceasing transmission.
摘要翻译：在接入终端与第二接入点（例如，宏小区）进行通信的情况下，在检测到第一接入点附近的接入终端时，第一接入点（例如，毫微微小区）的传输受到限制。在检测到这样的接入终端时，接入终端限制在接入终端主动接收来自第二接入点的信息的下行链路载波频率上的传输（例如信标发送）。接入点的这种传输限制可能涉及例如临时降低发射功率，减少传输周期或停止传输。

摘要： Systems and methods herein enable a mobile device to detect that a user is traveling in association with a vehicle based at least on motion data. In some embodiments, accelerometer data is used. Motion data is leveraged in combination with various observations regarding vehicular movement to determine whether or not a mobile device is located in or on the vehicle. For instance, before entering the state of vehicular movement, it can be determined that the user is first in a walking state (e.g., walking to the car, bus, etc., and entering it). Likewise, after exiting the state of vehicular movement, the user re-enters the walking state (e.g., after stepping out of the car, bus, etc., the user again begins walking). Further, it can be determined that when the user is in the walking state, the accelerometer signals appear different to any accelerometer signals seen in the vehicular movement state.

摘要： Techniques are provided to recognize a speaker's voice. In one embodiment, received audio data may be separated into a plurality of signals. For each signal, the signal may be associated with value/s for one or more features (e.g., Mel-Frequency Cepstral coefficients). The received data may be clustered (e.g., by clustering features associated with the signals). A predominate voice cluster may be identified and associated with a user. A speech model (e.g., a Gaussian Mixture Model or Hidden Markov Model) may be trained based on data associated with the predominate cluster. A received audio signal may then be processed using the speech model to, e.g.,: determine who was speaking; determine whether the user was speaking; determining whether anyone was speaking; and/or determine what words were said. A context of the device or the user may then be inferred based at least partly on the processed signal.

摘要： Techniques are disclosed for using the hardware and/or software of the mobile device to obscure speech in the audio data before a context determination is made by a context awareness application using the audio data. In particular, a subset of a continuous audio stream is captured such that speech (words, phrases and sentences) cannot be reliably reconstructed from the gathered audio. The subset is analyzed for audio characteristics, and a determination can be made regarding the ambient environment.
