DESCRIPTION (provided by applicant): According to the MarkeTrak VII survey (Kochkin 2008), there are roughly 35 million individuals in the US with some degree of hearing loss. Of these, almost 10 million have hearing aids and 67,000 have cochlear implants. The goal of auditory (re)habilitation (AR) programs is to build the listening skills of individuals with hearing loss, so that they can comprehend the language in their environment. With appropriate hearing devices and AR, individuals with hearing loss can begin to discriminate and identify the speech sounds in the spoken language around them. In Phase I of this project we developed an adaptive computer-guided AR software program called the Sound Identification Tutor (SIT) that focused on sound identification and discrimination. For a video demonstration showcasing the SIT please visit http://www.biospeech.com/research/ar.html. The SIT provides an automated sequence of sound targets to be trained and it chooses the type of target depending on the performance of the user. It also chooses whether to present the target in auditory or audiovisual mode. The SIT uses natural human audiovisual recordings of all the word targets. It also uses child-friendly images of simple words to make this software suitable and fun for children. The results of an evaluation of the software with 24 children and adults showed that over a course of 10 sessions subjects significantly improved their sound identification skills. Children benefitted more from the automated lesson sequence than adults. Adults tended to prefer to choose their own sound targets to train on. In addition, we showed that subjects improved on specific sound targets they trained on, but problematic targets from the pre-test that were not trained on did not improve in the post-test. This showcases the fact that improvements were not caused by increased exposure to speech but by training specific sound targets. In this Phase II proposal, we will extend the SIT and develop it into a marketable product. The proposal consists of the following aims: (i) To Build a Spanish Version of the SIT; (ii) To Extend the SIT with Words Embedded in Sentences with Optional Background Noise and Multiple Speakers; (iii) To Extend the Open- Ended Training Module of the SIT; (iv) To Expand the SIT to Create a DVD installer, Interface with the Web, and Develop an In-home Login UI; (v) To Evaluate the Program Specifically for In-home Use; (vi) To Create a Built-in Assessment Protocol to Produce User-specific Listening Intervention Plans PUBLIC HEALTH RELEVANCE: In the United States, there are roughly 35 million individuals with some degree of hearing loss and of these, almost 10 million have hearing aids and 67,000 have cochlear implants who need intensive auditory (re)habilitation (AR) training to fully realize the potential benefit of their prostheses and attain intelligible speech. Face-to-face AR training with a specialist is expensive, not always covered by insurance and not always feasible because clients may not have access to a specialist, esp. if they speak a different language. The proposed project will expand upon an adaptive computer-guided software program (the Speech Identification Tutor, SIT) that focuses on learning phoneme discrimination and identification and will provide a Spanish version of the software, provide additional synthetic voices for open-ended training, provide an additional adaptive sentence task where individuals are exposed to words embedded in sentences, with background noise, and multiple speakers and will be evaluated for in-home use by a larger group of users.

描述(由申请人提供)：根据MarkeTrak VII调查(Kochkin 2008)，美国大约有3500万人患有不同程度的听力损失。在这些人中，近1000万人戴上了助听器，6.7万人安装了人工耳蜗。听力康复(AR)计划的目标是培养听力损失患者的听力技能，使他们能够理解所在环境中的语言。有了适当的听力装置和AR，听力损失的人就可以开始辨别和识别他们周围口语中的语音。在这个项目的第一阶段，我们开发了一个自适应的计算机引导的AR软件程序，称为声音识别导师(SIT)，专注于声音识别和辨别。欲观看展示现场的视频演示，请访问http://www.biospeech.com/research/ar.html.SIT提供要训练的声音目标的自动序列，并根据用户的表现选择目标的类型。它还选择是以听觉模式还是以视听模式呈现目标。SIT使用所有单词目标的自然人类视听录音。它还使用简单文字的儿童友好图像，使这款软件适合儿童，并为儿童带来乐趣。该软件对24名儿童和成年人的评估结果显示，在10个疗程中，受试者的声音识别技能显著提高。与成年人相比，孩子们从自动授课序列中受益更多。成年人倾向于选择自己的声音目标进行训练。此外，我们发现，受试者在他们训练的特定声音目标上有所进步，但没有接受过训练的前测中有问题的目标在后测中没有改善。这表明，改善并不是由于增加了讲话时间，而是通过训练特定的声音目标来实现的。在这个第二阶段的提案中，我们将扩展SIT并将其开发成适销对路的产品。该提议包括以下目标：(1)建立西班牙语版本的SIT；(2)扩展SIT，在句子中嵌入单词，可选的背景噪音和多人发言；(3)扩展SIT的开放式培训模块；(4)扩展SIT，创建DVD安装程序，与Web接口，并开发家庭登录用户界面；(5)评估该计划，专门供家庭使用；(6)创建内置评估协议，以制定用户特定的听力干预计划 公共卫生相关性：在美国，大约有3500万人患有不同程度的听力损失，其中近1000万人戴着助听器，6.7万人安装了人工耳蜗，他们需要强化听觉(恢复)训练，以充分实现其假体的潜在好处，并获得清晰的语音。与专家面对面的AR培训是昂贵的，并不总是由保险覆盖，并且并不总是可行的，因为客户可能无法接触到专家，特别是。如果他们说一种不同的语言。拟议的项目将扩展一个以学习音素辨别和识别为重点的自适应计算机指导的软件程序(语音识别导师，SIT)，并将提供该软件的西班牙语版本，为开放式培训提供更多的合成声音，提供额外的自适应句子任务，使个人接触到句子中嵌入的单词、有背景噪音和多个发言者，并将为更大的用户群体的家庭使用进行评估。
