    摘要： The acoustic speech signal is decomposed into wavelets arranged in an asymmetrical tree data structure from which individual nodes may be selected to best extract local features, as needed to model specific classes of sound units. The wavelet packet transformation is smoothed through integration and compressed to apply a non-linearity prior to discrete cosine transformation. The resulting subband features such as cepstral coefficients may then be used to construct the speech recognizer's speech models. Using the local feature information extracted in this manner allows a single recognizer to be optimized for several different classes of sound units, thereby eliminating the need for parallel path recognizers.

    摘要翻译： 声学语音信号被分解成以不对称树数据结构排列的小波，根据需要可以选择各个节点以最佳地提取局部特征，以模拟特定类别的声音单元。 小波包变换通过积分进行平滑，并进行压缩，以在离散余弦变换之前应用非线性。 所得到的子带特征如倒谱系数可以用于构建语音识别器的语音模型。 使用以这种方式提取的局部特征信息允许为多个不同类别的声音单元优化单个识别器，从而消除对并行路径识别器的需要。

    摘要： A noise robustness method operates jointly in a signal domain and a model domain. For example, energy is added in the signal domain for frequency bands where an actual noise level of an incoming signal is lower than a noise level used to train models, thus obtaining a compensated signal. Also, energy is added in the model domain for frequency bands where noise level of the incoming signal or the compensated signal is higher than the noise level used to train the models. Moreover, energy is never removed, thereby avoiding problems of higher sensitivity of energy removal to estimation errors.

    摘要翻译： 噪声鲁棒性方法在信号域和模型域中共同操作。 例如，在信号域中增加能量，其中输入信号的实际噪声电平低于用于训练模型的噪声电平，从而获得补偿信号。 此外，在模型域中增加能量，其中输入信号或补偿信号的噪声电平高于用于训练模型的噪声电平的频带。 此外，能量永远不会被去除，从而避免了能量去除对估计误差的更高灵敏度的问题。

    摘要： A system and method for identifying a user of a handheld device is herein disclosed. The device implementing the method and system may attempt to identify a user based on signals that are incidental to a user's handling of the device. The signals are generated by a variety of sensors dispersed along the periphery or within the housing. The sensors range may include touch sensors, inertial sensors, acoustic sensors, pulse oximiters, and a touchpad. Based on the sensors and corresponding signals, identification information is generated. The identification information is used to identify the user of the handheld device. The handheld device may implement various statistical learning and data mining techniques to increase the robustness of the system. The device may also authenticate the user based on the user drawing a circle, or other shape.

    摘要： An embedded device for playing media files is capable of generating a play list of media files based on input speech from a user. It includes an indexer generating a plurality of speech recognition grammars. According to one aspect of the invention, the indexer generates speech recognition grammars based on contents of a media file header of the media file. According to another aspect of the invention, the indexer generates speech recognition grammars based on categories in a file path for retrieving the media file to a user location. When a speech recognizer receives an input speech from a user while in a selection mode, a media file selector compares the input speech received while in the selection mode to the plurality of speech recognition grammars, thereby selecting the media file.

    摘要： The handheld case of the remote control unit includes at least one touchpad, and other sensors, such as acceleration sensors, case perimeter sensors, pressure sensors, RF signal sensors. These sensors provide a rich array of sensory inputs that are classified by a pattern recognizer to generate control commands for both the consumer electronic equipment and the remote control unit itself. A power management system to conserve unit battery power is also responsive to the pattern recognizer to allow intelligent power management control. The control system uses the display of the consumer electronic equipment to provide instructions to the user, and the behavior of the remote control system uses what is displayed on the display as context information for pattern recognition.

    摘要： A remote control unit selectively transmits a control signal for remotely controlling an electronic device. The unit defines an imaginary cut plane that substantially bisects the unit. The unit includes a plurality of input features collectively disposed symmetrically with respect to the imaginary cut plane. The input features include a first and second input feature. The first and second input features are disposed on opposite sides of the cut plane. Furthermore, the unit includes a sensor that detects a first and second holding position of the unit. The first holding position and the second holding position are substantially opposite to each other. Moreover, the unit includes a controller that associates the control signal with the first input feature when the sensor detects the first holding position, and the controller associates the control signal with the second input feature when the sensor detects the second holding position.
