汉语语音识别中区分性声调模型及最优集成方法     

黄浩  朱杰 《东南大学学报》2007,23(2):174-178

提出了2种解决汉语语音识别中声调问题的方法:利用区分性方法对基于隐马尔可夫模型(HMM)的声调模型进行训练;提出将区分性训练的声调模型加入大词汇量连续语音识别系统的最优方法,该方法根据最小音子错误的训练准则以及利用扩展Baum-Welch算法区分性训练与模型相关的概率权重,对声学模型以及声调模型概率进行加权.实验结果表明区分性训练的声调模型能够显著地提高连续语音声调识别率以及大词汇量语音识别系统的识别率,同时区分性的模型权重训练能够在区分性声调模型加入连续语音识别系统之后进一步提高系统的识别性能.  相似文献   

基于CDS的4G移动通信实验教学系统构建     

陈万通  冯青  王续乔  吴志军 《教育教学论坛》2020,(14):385-387

移动通信是通信工程专业与行业紧密结合的一门专业必修课,但多数高校面临“商用4G-学校2G”的尴尬局面。文章针对课程实验教学与现行4G网络结合较差的问题,基于LTE无线网络测试软件CDS和移动终端设计4G移动通信实验课程。该方案易实施、投入小,有助于学生深刻掌握LTE系统信令流程,培养网络数据采集与分析等工程能力,对高等院校实施工程教育以及4G实验室建设具有重要参考价值。  相似文献   

Designing learning experiences for outdoor hybrid learning spaces     

Kadri Mettis  Terje Väljataga 《British journal of educational technology : journal of the Council for Educational Technology》2021,52(1):498-513

With the support of various personal and institutional mobile technologies, numerous physical and virtual spaces can be turned into interesting and motivating hybrid learning settings. By its nature, outdoor mobile learning happens on the move is connected to specific locations and settings inviting learners to study their surroundings, inquire about natural phenomena and solve complex real-life problems. This poses challenges for teachers to design meaningful, contextualized and comprehensive learning experiences. The paper aims to explore what kind of mobile learning scenarios K-12 teachers create and what are the limitations and development perspectives of these scenarios. Content analysis of 25 location-based outdoor learning tracks with 465 questions and tasks was carried out. The results demonstrate that designing and implementing learning activities outside the safe, familiar classroom environment in new hybrid learning spaces is a challenging task for the teachers on many different levels. Taking Bloom’s revised taxonomy, types of contextualization and integrated learning models as frameworks for content analysis of the learning scenarios, the study shows that the teachers do not perceive the potential hybrid spaces and mobile technologies offer in order to design consistent learning experiences that emphasize higher order thinking levels, encompass contextual information and integrate knowledge from multiple disciplinary sources. The paper concludes that there is a need for more teacher training and systemic interventions into current teaching practices that encourage teachers to step outside of their existing teaching paradigms to acknowledge the pedagogical potential of hybrid learning spaces as well as the technological affordances.  相似文献

Effect of gender differences on 3-on-3 basketball games taught in a mobile flipped classroom     

Tosti Hsu-Cheng Chiang  Chengjiu Yin 《Interactive Learning Environments》2019,27(8):1093-1105

ABSTRACT

Physical education emphasizes learning sports skills, which is why it is usually conducted in a face-to-face manner. Instructors focus on explaining rules and demonstrating moves, which the learners are required to repeat and imitate. Flipped classrooms have become a trend; thus, the present study investigated their influence on physical education. A mobile application for novice and advanced basketball players was developed and tested in a course teaching 3-on-3 basketball and various teaching methods were implemented to test for the effects of gender differences on learning outcome. The participants were students enrolled in the aforementioned course in a university in central Taiwan. 326 participants were included in the study, of whom 238 were male and 88 were female. The duration of the experiment was 5 weeks between May and June 2017, during which the correctness of moves, maneuverability, teamwork, sense of balance, and adaptability of the participants were evaluated and graded as their learning outcome. The research team observed the participants each week to gather empirical data for analysis. The results indicate that a mobile flipped classroom is the optimal teaching strategy, followed by projecting teaching; therefore, a mobile flipped classroom is the recommended approach to be integrated into physical education.  相似文献
