说话人识别中基于音素分类的数据选择方法

在说话人识别中,有效语音数据的选择是一个重要的预处理环节.常用的数据选择方法根据能量信息的强弱对有效数据进行提取,但在实际情况中能量的高低与语音数据并无必然联系.本文在对传统方法进行分析比较的同时引入语言学知识,提出基于辅音信息的有效数据选择方法.该方法通过对活动语音检测结果中音素识别结果进行分析,保留所有元音,对辅音进行筛选,去除无益于说话人识别的干扰辅音音素,从而实现对有效语 音数据的选取.实验表明,应用该方法得到的说话人识别结果,明显优于传统的基于能量的数据选择算法,如基于G.723.1标准的活动语音检测算法和近期提出的基于交叉熵顺序统计滤波的端点检测算法.     

Negotiating contradictions in developing teacher identity during the EAL practicum in Australia

This paper reports on how Maria (pseudonym), a non-native English speaker (NNES) and preservice teacher (PST) of English as an additional language (EAL), developed her professional identity during the practicum in an Australian secondary school. Drawing on activity theory, the study identified contradictions in Maria’s practicum activity and examined how Maria’s professional identity developed through her negotiation of the contradictions. Data included interviews with Maria before, during and after the practicum, her reflections, an interview with her school mentor (Ms Davies, pseudonym), and relevant documents. The findings reveal that Maria experienced contradictions between her multiple identities of NNES, student, becoming teacher, and classroom teacher, between her mentor’s teaching approach and that of her own, and between her practice and rules. The findings provide implications for researching teacher identity and supporting preservice EAL teachers in developing productive teacher identities during the practicum.

Exploring knowledge management perspectives in smart city research: A review and future research agenda

There is a growing body of literature calling for work on the emerging role of smart cities as information hubs and knowledge repositories. This article reviews the existing smart city literature and integrates knowledge management perspectives to provide an overview of future research directions. By demonstrating the multi-stakeholder relationships involved in smart city development, it takes a crucial step towards looking into the role of knowledge management in future smart city research. Eighty-two peer-reviewed publications were analyzed covering smart city studies in various research domains. The systematic review identifies five different themes: strategy and vision, frameworks, enablers and inhibitors, citizen participation, and benefits. These themes form the basis for developing a future research agenda focused on knowledge sharing and co-learning among cities via three research directions: socio-technical approaches, knowledge sharing perspectives and organizational learning capabilities. The paper also proposes a series of knowledge-driven policy recommendations to contribute towards the UN Sustainable Development Goals.
