在本文中，我们报告了我们最近的努力，收集语料库的口语演讲材料，这将使研究导向快速，准确，方便地访问讲座内容。到目前为止，我们已经收集了270小时的演讲语料库，来自各种本科课程和研讨会。我们报告的初步分析，在这些数据和词汇的使用模式在三个课程的自发语音现象。最后，我们研究了从书面和口头材料训练的语言模型困惑，并描述了一个课程的初步识别实验。
In this paper we report on our recent efforts to collect a corpus of spoken lecture material that will enable research directed towards fast, accurate, and easy access to lecture content. Thus far, we have collected a corpus of 270 hours of speech from a variety of undergraduate courses and seminars. We report on an initial analysis of the spontaneous speech phenomena present in these data and the vocabulary usage patterns across three courses. Finally, we examine language model perplexities trained from written and spoken materials, and describe an initial recognition experiment on one course.
