摘要： The present invention provides a dispersion compensator which utilizes a Virtually Imaged Phased Array (VIPA), gratings, and birefringent wedges to moderate chromatic dispersion, dispersion slope and polarization mode dispersion, and a method and system for testing such a dispersion compensator. The dispersion compensator in accordance with the present invention propagates the composite optical signal in a forward direction; separates the wavelengths in the band of wavelengths in each of the plurality of channels, where each of the wavelengths in the band is spatially distinguishable from the other wavelengths in the band; spatially separates each band of wavelengths in the plurality of channels; spatially separates each wavelength of each separated band of wavelengths into a plurality of polarized rays; and reflects the plurality of polarized rays toward a return direction, where dispersion is added to the reflected plurality of polarized rays such that the unwanted chromatic dispersion, dispersion slope, and PMD are compensated. The dispersion compensator provides simultaneous tunable compensation of these various dispersions utilizing a single apparatus. A system which utilizes the compensator is thus cost effective to manufacture. Systems may be provides which determines the operating and performance parameters for the compensator, and measures the spectrum outputted by the compensator.

摘要： The disclosure describes methods for synthesis of accurate visible speech using transformations of motion-capture data. Methods are provided for synthesis of visible speech in a three-dimensional face. A sequence of visemes, each associated with one or more phonemes, are mapped onto a three-dimensional target face, and concatentated. The sequence may include divisemes corresponding to pairwise sequences of phonemes, wherein the diviseme is comprised of motion trajectories of a set facial points. The sequence may also include multi-units corresponding to words and sequences of words. Various techniques involving mapping and concatenation are also addressed.

摘要： System and methods for robust multiple speaker segmentation in noisy conversational speech are presented. Robust voice activity detection is applied to detect temporal speech events. In order to get robust speech features and detect speech events in a noisy environment, a noise reduction algorithm is applied, using noise tracking. After noise reduction and voice activity detection, the incoming audio/speech is initially labeled as speech segments or silence segments. With no prior knowledge of the number of speakers, the system identifies one reliable speech segment near the beginning of the conversational speech and extracts speech features with a short latency, then learns a statistical model from the selected speech segment. This initial statistical model is used to identify the succeeding speech segments in a conversation. The statistical model is also continuously adapted and expanded with newly identified speech segments that match well to the model. The speech segments with low likelihoods are labeled with a second speaker ID, and a statistical model is learned from them. At the same time, these two trained speaker models are also updated/adapted once a reliable speech segment is identified. If a speech segment does not match well to the two speaker models, the speech segment is temporarily labeled as an outlier or as originating from a third speaker. This procedure is then applied recursively as needed when there are more than two speakers in a conversation.
摘要翻译：提出了在嘈杂会话语音中强大的多个说话人分割的系统和方法。应用鲁棒的语音活动检测来检测时间语音事件。为了获得鲁棒的语音特征并在噪声环境中检测语音事件，使用噪声跟踪应用降噪算法。在降噪和语音活动检测之后，进入的音频/语音最初被标记为语音段或静音段。在没有对扬声器数量的先验知识的情况下，系统在对话语音开头附近识别出一个可靠的语音段，并且以较短的等待时间提取语音特征，然后从所选语音段学习统计模型。该初始统计模型用于识别会话中的后续语音段。统计模型也通过与模型匹配的新识别语音段不断适应和扩展。具有低可能性的语音片段用第二扬声器ID标记，并从中学习统计模型。同时，一旦识别出可靠的语音段，这两个训练有素的扬声器模型也被更新/调整。如果语音段与两个说话者模型不匹配，则语音段被临时标记为异常值或者来自第三扬声器。当会话中有两个以上的扬声器时，根据需要递归地应用该过程。
