针对非平稳噪声环境下的语音活动检测问题,提出了基于在线单类SVM的自适应语音活动检测算法。该算法采用单类SVM对多种特征信息进行在线学习与综合,为非平稳背景噪声建模,并采用双层决策机制,能有效提高语音活动检测的稳健性。在语音识别系统中的实验结果表明,算法在多种噪声环境和信噪比条件下有效,并明显提高了在非平稳噪声环境下的识别率。 相似文献

底层文学已成为新世纪文学创作的一种趋向,作为一种异质性的文学创作逐渐引起批评界和理论界的关注。关注底层求生者,关注底层求生者的生存焦虑和身份焦虑,也成为底层写作者抒写的一种范式,注重从心灵的探讨以期寻求人性的思考,在关注底层求生者生存境况的前提下更注重从心理去捕捉他们希望的追寻与失落。 相似文献

This research investigated the relationships among symptoms associated with attention‐deficit/hyperactivity disorder (ADHD), perceived stress, and resilience in college students. In our study of 558 college students (175 men, 383 women), we confirmed the hypothesis that the relationship between ADHD symptoms and perceived stress is mediated by protective factors associated with resilience. The relationships were not significantly moderated by sex. Implications for increasing resilience in college students and lowering perceived stress for college students are discussed. 相似文献

Many teachers are sporadic in using evidence-based practice (EBP) concerning students with autism spectrum disorder (ASD). Numerous reasons have been posited for this. However, no single study has worked to understand the relative importance of identified criteria in the EBP decision-making processes of teachers. Through the development of a new survey tool, the Evidence-Based Practice Innovation Survey (EBPIAS), an exploration of the decision-making process of Australian teachers in their adoption and cessation of EBP was undertaken. Teachers rated the perception that an EBP would meet the needs of their students as the most important criteria in determining their use of EBP. Conversely, the judgement that an EBP did not meet the needs of their student was the most important criteria in their decision to cease use. In comparing the relevant importance of identified criteria, teachers rated the perception of training as the second-lowest consideration in their decision to adopt and cease using EBP. Consequently, there may need to be greater promotion of, or information concerning, the training required by teachers for effective implementation supporting a more balanced and holistic approach in assessing criteria impacting the adoption of EBP by teachers in the first instance, potentially lowering cessation rates. 相似文献

“没”和“了”同现的句子存在多种结构、语义类型。对相关语言事实的充分观察是合理解释的前提。选择解释的角度需要充分考虑系统性和易接受性。表达“异于常态”的意义、处于不相邻层次,这两个因素对于分析“没”、“了”同现句可以有较强的解释力。汉语的“异常态”表达系统有待系统研究。 相似文献

Children in their final year of primary school (Year 6) were asked about their experiences of transition to high school so far. This multi‐method study included questionnaires, discussion, drawing and writing. The children raised a range of issues including mixed feelings; friends; bullying; getting lost; race; being the only child from their primary school; teachers; growing up; and school choice. Learning issues were rarely raised, suggesting that the social aspects of the move are most important for children at the end of Year 6. Most students wanted as much experience of their new school as possible, before they start attending there as a pupil. A key finding from this study is that children can be a very valuable resource in improving transition. Given accessible opportunities, which need not take up large amounts of time or resources, all children can inform the transition process and contribute to ongoing improvement. 相似文献

汉英双语属于不同的语系。在语言结构、表意方法上都有很大差异,这就决定了英汉翻译应以表意为基础不能刻意追求形式对等。在处理不对等时,应以变通手段来应对。本文主要就英汉被动语态的不对等情况,提出一些变通方法,如意译、成分转换等。 相似文献
