摘要： The present disclosure presents a useful metric for assessing the relative difficulty which non-native speakers face in pronouncing a given utterance and a method and systems for using such a metric in the evaluation and assessment of the utterances of non- native speakers. In an embodiment, the metric may be based on both known sources of difficulty for language learners and a corpus-based measure of cross-language sound differences. The method may be applied to speakers who primarily speak a first language speaking utterances in any non-native second language.
摘要翻译：本公开提供了一种用于评估非母语者在发音给定语音时面临的相对难度的有用指标，以及在评估和评估非母语者话语时使用这种度量的方法和系统。在一个实施例中，度量可以基于用于语言学习者的已知的困难来源和基于语料库的跨语言音差的度量。该方法可以应用于主要以任何非本地第二语言讲第一语言说话的扬声器。

摘要： A computer-implemented method, system, and computer program product for automatically assessing text difficulty. Text reading difficulty predictions are expressed on a scale that is aligned with published reading standards. Two distinct difficulty models are provided for informational and literary texts. A principal components analysis implemented on a large collection of texts is used to develop independent variables accounting for strong intercorrelations exhibited by many important linguistic features. Multiple dimensions of text variation are addressed, including new dimensions beyond syntactic complexity and semantic difficulty. Feedback about text difficulty is provided in a hierarchically structured format designed to support successful text adaptation efforts. The invention ensures that resulting text difficulty estimates are unbiased with respect to genre, are highly correlated with estimates provided by human experts, and are based on a more realistic model of the aspects of text variation that contribute to observed difficulty variation.
摘要翻译：一种用于自动评估文本难度的计算机实现的方法，系统和计算机程序产品。文本阅读难度预测以与公布的阅读标准相一致的规模表达。为信息和文学文本提供了两个不同的难题模型。使用大量文本进行的主要组成分析来开发独立变量，以衡量许多重要语言特征所表现的强相互关联。解决文本变体的多个维度，包括超越句法复杂性和语义难度的新维度。关于文本难度的反馈以分层结构的格式提供，旨在支持成功的文本适应工作。本发明确保所得到的文本难度估计对于类型是不偏不倚的，与人类专家提供的估计高度相关，并且基于有助于观察到的难度变化的文本变化方面的更现实的模型。
