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）：该项目的目标是开发和测试一种使用虚拟临床医生对失语症患者进行计算机自动化治疗的方法。我们建议将联合收割机的研究结果结合起来，这些研究结果来自一项专注于治疗中风后语法缺失的工作计划，该计划有相当多的有效性数据，即，基础形式的治疗（TUF）（Thompson et al. 2003），具有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。虽然这项工作的组成部分已经到位，但从未合并，因此是创新性研究。我们建议开发一个“虚拟失语症临床医生”，将能够提供刺激失语症治疗。将对自动化系统进行评估，以确定失语症患者是否有可能独立使用该系统，以进一步促进他们在语言恢复方面的进展，超出当前医疗保健政策下有限的临床接触所预期的结果。如果成功的话，这个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协议开发系统，用于训练语法复杂的句子。第2阶段将实施和实验性评估第1阶段开发的自动TUF导师（TUF-T）协议的有效性。我们建议比较传统的，临床医生提供的TUF两个TUF-T条件，一个与临床医生调解和一个没有。工作假设是，TUF-T将更有效，或同等有效，临床医生管理的TUF时，时间和临床医生的成本限制，以及语言的改善被认为是。如果成功的话，这项工作将为语音和语言障碍的管理带来新的方向，并利用计算机技术的进步。
