DESCRIPTION (provided by applicant): The goal of this project is to develop and test a computer-automated treatment for individuals with aphasia using a virtual clinician. We propose to combine the research findings resulting from a program of work focused on treatment of post-stroke agrammatism, for which there are considerable available efficacy data, i.e., Treatment of Underlying Forms (TUF) (Thompson et al. 2003), with a well-developed and tested interactive computer system that enables face-to-face communication with an intelligent animated agent developed at the Center for Spoken Language Research (CSLR) at the University of Colorado. Although the components for this work are in place, they have never been combined and thus represent innovative research. We propose to develop a "virtual aphasia clinician" that will be capable of delivering stimuli for aphasia treatment. The automated system will be evaluated for its potential independent use by aphasic individuals to further their progress in language recovery beyond what might be expected to result from the limited clinical contact available under current healthcare policy. If successful, this project will lay the groundwork for a next step - to develop speech recognition software permitting the virtual clinician to evaluate aphasic users' verbal responses. In Phase I of the project we will develop the system using presently available TUF protocols for training syntactically complex sentences. Phase 2 will implement and experimentally assess the effectiveness of the automated TUF-tutor (TUF-T) protocols developed in Phase 1. We propose to compare traditional, clinician-delivered TUF to two TUF-T conditions, one with and one without clinician mediation. The working hypothesis is that TUF-T will be more effective than, or equally effective as, clinician-administered TUF when time and clinician-cost restraints, as well as language improvement are considered. If successful, this work will result in new directions for the management of speech and language disorders that incorporate and take advantage of advances in computer technology.

描述（由申请人提供）：该项目的目的是针对使用虚拟临床医生为失语症患者开发和测试计算机自动化的治疗方法。我们建议将重点是治疗后击球后的工作计划引起的研究结果结合，为此，有大量可用的疗效数据，即对基本形式的治疗（TUF）（Thompson等，2003），以及A和A经过良好开发和测试的交互式计算机系统，可以与科罗拉多大学口语研究中心（CSLR）开发的智能动画代理进行面对面的交流。尽管这项工作的组成部分已经到位，但它们从未合并过，因此代表了创新的研究。我们建议开发一个“虚拟失语症临床医生”，该临床医生将能够提供刺激以进行失语治疗。自动化系统的潜在独立用途将被评估，该系统的潜在独立使用，以进一步发展其语言恢复的进步，超出了当前医疗保健政策可获得有限的临床接触所产生的预期。如果成功，该项目将为下一步提供基础 - 开发语音识别软件，允许虚拟临床医生评估失语症用户的口头反应。在该项目的第一阶段，我们将使用目前可用的TUF协议来开发系统，以训练句法复杂的句子。第2阶段将在第1阶段开发的自动化TUF Tutor（TUF-T）方案的有效性并在实验中评估。我们建议将传统的，临床医生交付的TUF与两个TUF-T进行比较，这是两个TUF-T条件，一种没有临床医生调解。工作假设是，在时间和临床医生成本的约束以及语言改善时，TUF-T将比临床医生管理的TUF更有效或同样有效。如果成功，这项工作将为融合并利用计算机技术进步的语音和语言障碍的管理提供新的方向。
