    • A system and method for speaker recognition speaker modelling whereby prior speaker information is incorporated into the modelling process, utilising the maximum a posteriori (MAP) algorithm and extending it to contain prior Gaussian component correlation information. Firstly a background model (10) is estimated. Pooled acoustic reference data (11) relating to a specific demographic of speakers (population of interest) from a given total population is then trained via the Expectation Maximization (EM) algorithm (12) to produce a background model (13). The background model (13) is adapted utilising information from a plurality of reference speakers (21) in accordance with the Maximum A Posteriori (MAP) criterion (22). Utilizing MAP estimation technique, the reference speaker data and prior information obtained from the background model parameters are combined to produce a library of adapted speaker models, namely Gaussian Mixture Models (23).
    • 一种用于说话者识别扬声器建模的系统和方法,其中先前的说话者信息被并入到建模过程中,利用最大后验(MAP)算法并将其扩展为包含先前的高斯分量相关信息。 首先估计一个背景模型(10)。 然后通过期望最大化(EM)算法(12)训练与给定总人口的特定人群(兴趣人群)有关的汇集的声学参考数据(11)以产生背景模型(13)。 背景模型(13)根据最大后验(最大后验)(MAP)标准(22)利用来自多个参考扬声器(21)的信息。 利用MAP估计技术,将从背景模型参数获得的参考说话者数据和先验信息相结合,以产生适应的说话者模型库,即高斯混合模型(23)。

    • Absorbent structures are disclosed which may be incorporated into liquid absorbent products, such as diapers, adult incontinence products, feminine hygiene products, and the like. The absorbent structures are made from a fibrous material and include a pair of opposing lateral flaps. The lateral flaps are folded onto the fibrous web. By folding the lateral flaps onto the fibrous web, greater basis weight areas may be formed on the absorbent structure. By varying the width of the lateral flaps, the basis weight differential may be increased and decreased. The lateral flaps also form the widest portion of the web material for facilitating folding during a continuous process. Through the system and process of the present invention, a fibrous web having a substantially uniform basis weight may be converted into absorbent structures having a differential basis weight with little or no waste produced. Further, the absorbent structures may be formed without having to subject the fibrous web to a scarfing process.
    • 公开了吸收结构,其可以并入液体吸收产品中,例如尿布,成人失禁产品,女性卫生产品等。 吸收结构由纤维材料制成并且包括一对相对的侧翼。 侧片折叠在纤维网上。 通过将侧翼折叠到纤维网上,可以在吸收结构上形成更大的基重区域。 通过改变侧翼的宽度,可以增加和减小基重差。 横向翼片也形成幅材材料的最宽部分,以便于在连续过程中折叠。 通过本发明的系统和方法,具有基本均匀基重的纤维网可以转化成具有差异基重的吸收结构,很少或不产生废物。 此外,可以形成吸收结构,而不必将纤维网进行剥皮处理。
