Project LISTEN (Literacy Innovation that Speech Technology ENables) at Carnegie Mellon University. It has been supported by National Science Foundation under IERI〔(IERI )〕 and ITR〔(ITR )〕 programs, but currently it is supported by the U.S. Department of Education’s Institute of Educational Sciences〔(Institute of Educational Sciences )〕 under Grants R305B070458, R305A080157 and R305A080628, and by the Heinz Endowments.〔(Heinz Endowments )〕 The Project is an initiative to create a novel tool to improve literacy. It works like an automated Reading Tutor which displays stories on computer screen and simultaneously listens to children read loud. This project is described as ‘an automated reading Tutor’.〔(【引用サイトリンク】title=Project LISTEN A Reading Tutor That Listens )〕 The project is headed by David 'Jack' Mostow, Ph.D. It has used the cepstral N-gram stochastic and language-level models of CMU Sphinx to evaluate oral reading and speaking proficiency and provide literacy tutelage. This project contributes to and provides unique opportunities for educational data mining. It is not a commercial project yet, but has been used by hundreds of children as part of its research and testing.〔(【引用サイトリンク】title=Project LISTEN A summary )〕 In 2005, the LISTEN reading tutor was pilot-tested in Ghana, launching Project Kané.〔(Project Kané )〕 ==How it works== To make the user experience authentic and pleasant in assisted reading,〔(assisted reading )〕 a story can be selected by the child from a menu listing interesting stories from the Weekly Reader or another sources which also includes user authored stories. Further, a tutor listens to the children read aloud using Carnegie Mellon’s Sphinx – II Speech Recognizer〔(【引用サイトリンク】title= CMU Sphinx Speech Recognition Toolkit )〕〔(【引用サイトリンク】title= CMU Sphinx-II User Guide )〕 to process and interpret the student's oral reading. When a student makes mistakes, gets stuck or clicks for help then the tutor intervenes in the process.〔(【引用サイトリンク】title= Project Listen Description )〕 Then, the tutor responds with assistance modeled in part after expert reading teachers adapted to the limitations and capability of technology. The Reading Tutor dynamically updates the estimate data of student’s reading level, and picks stories a bit harder according to their level; this approach allows the tutor to focus on the zone of proximal development. It also scaffolds key processes in reading. It explains unfamiliar word sand concepts by presenting short factoids (comparison to other words). It also provides spoken and graphical assistance when it notices student click for help, get stuck, skip a word, misread word or make a mistake. Visual speech of the tutor makes use of talking mouth video clips of phonemes. It assists word identification by previewing new words and reading hard words aloud. It also motivates students by praising their good performance. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Project LISTEN」の詳細全文を読む スポンサード リンク
