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)：这个项目的目标是开发和测试一种使用虚拟临床医生的计算机自动治疗失语症的方法。我们建议结合一项专注于卒中后语法障碍治疗的工作计划所产生的研究结果，对于该计划，有相当多的有效数据，即潜在形式的治疗(TUF)(Thompson等人)。2003)，具有经过良好开发和测试的交互式计算机系统，该系统能够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交流。尽管这项工作的组成部分已经到位，但它们从未结合在一起，因此代表着创新研究。我们建议开发一种“虚拟失语症临床医生”，它将能够为失语症治疗提供刺激。该自动化系统将由失语症患者评估其潜在的独立使用，以进一步推动他们在语言恢复方面的进展，而不是目前医疗政策下有限的临床接触可能导致的结果。如果成功，该项目将为下一步奠定基础-开发语音识别软件，允许虚拟临床医生评估失语症用户的言语反应。在项目的第一阶段，我们将使用目前可用的TUF协议开发该系统，用于训练句法复杂的句子。第二阶段将实施和实验评估在第一阶段开发的自动TUF-T(TUF-T)方案的有效性。我们建议将传统的、临床医生提供的TUF-T与两种情况进行比较，一种是有临床医生调解的，另一种是没有临床医生调解的。工作假设是，考虑到时间和临床医生成本的限制，以及语言的改善，TUF-T将比临床医生管理的TUF更有效，或者与临床医生管理的TUF同等有效。如果成功，这项工作将为言语和语言障碍的管理带来新的方向，纳入并利用计算机技术的进步。
