Reading Remediation Using Computer Speech Recognition

在我们的学校里，阅读障碍的发生率高得令人无法接受，导致严重而广泛的社会、政治和经济问题。尽管有有效的教学计划，这种情况还是会发生。不幸的是，教师往往没有必要的培训或时间来实施这些计划。此外，有时将这些项目与规模较小或分散的学生项目一起使用并不划算。该项目将把先进的语音识别技术与计算机提供有效的、经过研究验证的阅读程序相结合，以有效和经济的方式向小学重拨和有风险的学生传授基本阅读技能。在第一阶段，使用我们的工作人员为当地方言培训的语音识别器对表现不佳的学生进行了前十节课的评估，并对类似的学生进行了“标准护理”。在一项随机试验中，治疗对象在音素分割方面的改善明显高于对照组。在第二阶段，我们将为小学生开发完整的100语音识别辅导阅读计划。该计划将包括一个对美国方言地区敏感的语音识别引擎，教学内容的完整多媒体呈现，印刷材料和所有必要的硬件。该计划的有效性将在随机对照试验中进行测试。建议的商业应用：这个项目将为小学低年级的学生制作一个100节课的辅导计划。该产品将吸引那些没有得到服务的表现不佳、处于危险之中、有补习能力和学习障碍的读者的学校以及国内市场。

Reading failure occurs in our schools at unacceptably high levels, causing serious and widespread social, political, and economic problems. This occurs despite the availability of effective instructional programs. Unfortunately, teachers often do not have the necessary training or time to implement these programs. In addition, it is sometimes not cost effective to use these programs with small or scattered student programs. This project will incorporate advanced speech recognition technology with the computer delivery of an effective, research-proven reading programs to effectively and economically teach basic reading skills to elementary redial and at-risk students. In Phase I, the first ten lessons were produced and evaluated with low- performing students using a speech recognizer trained by our staff for local dialect and similar students receiving "standard care." In a randomized trial, the treatment subjects improved significantly more than controls on phonemic segmentation. In Phase II, we will develop the complete 100 speech recognition remedial reading program for elementary students. The program will include a speech recognition engine that is sensitive to the dialect regions of the United States, complete multimedia presentation of instructional content, printed materials and all necessary hardware. The effectiveness of the program will be tested in a randomized control trial. PROPOSED COMMERCIAL APPLICATIONS: This project will produce a 100-lesson remedial program for students in the early elementary grades. The product will be attractive to schools with unserved low-performing, at-risk, remedial, and learning disabled readers, as well as to the home market.
