    摘要： Described is noise reduction technology generally for speech input in which a noise-suppression related gain value for the frame is determined based upon a noise level associated with that frame in addition to the signal to noise ratios (SNRs). In one implementation, a noise reduction mechanism is based upon minimum mean square error, Mel-frequency cepstra noise reduction technology. A high gain value (e.g., one) is set to accomplish little or no noise suppression when the noise level is below a threshold low level, and a low gain value set or computed to accomplish large noise suppression above a threshold high noise level. A noise-power dependent function, e.g., a log-linear interpolation, is used to compute the gain between the thresholds. Smoothing may be performed by modifying the gain value based upon a prior frame's gain value. Also described is learning parameters used in noise reduction via a step-adaptive discriminative learning algorithm.

    摘要： The present invention disclosed a method and system of replacing smart cards. It uses a new identification device (a new SIM) to replace an old one (an old SIM) associated with a user account. The new identification device has an identification number (ICCID). The new identification device is activated in the following manner. The old identification device communicates with an identification-management center through a communication interface (mobile telephone). And the identification-management center recognizes the old identification device. The identification number of the new identification device is sent to the identification-management center through the communication interface. The identification-management center checks the identification number. If the identification number is correct, the user account will be assigned to the new identification device by the identification-management center.
