The overarching goal of the proposed research is to provide much-needed evidence forthe impact of hearing loss on speech communication in children whose dominant language is Spanish (SL2). Due to their language background, even SL2 listeners with normal hearing are known to face more challenges than native listeners in adverse listening conditions. However, if they are considered proficient in English, typically-developing non-native children with normal hearing receive no accommodations in schools. The intervention services offered to non-native children with hearing loss are identical to those for their native peers, even though little is known about the impact of hearing loss on speech communication for any non-native population. The Specific Aims in the proposed research project are to establish the bases for speech perception in SL2 listeners with normal hearing (Aim 1) and hearing loss (Aim 2). By comparing the speech-perception ability in adult and child native English listeners and SL2 listeners with and without hearing loss, studies under each aim will evaluate the individual and conspiring influences of listeners' language background, hearing status, and age on phoneme perception in commonly encountered challenging listening environments. Using speech materials varying in the amount of contextual cues, the role of top-down and bottom-up processing will be examined. Data will be analyzed using a new approach that specifically quantifies the influence of above factors on confusion patterns for consonants. The data obtained as part of this proposed research will serve as a basis to determine whether poor speech perception in SL2 listeners is due to language background or to hearing loss. This, in turn, will have a positive impact on evaluation processes, academic outcomes, and cost effectiveness of services offered to non-English-speaking children under The Individuals with Disabilities Education Act and help them succeed academically and economically. This significant aspect of the proposed research is also consistent with the objective under "Hearing and Other Sensory or Communication Disorders" in Healthy People 2020.

拟议的研究的总体目标是为急需的证据提供证据 听力损失对主导语言为西班牙语（SL2）的儿童语音交流的影响。 由于他们的语言背景，即使是正常听力的SL2听众也会面对更多 在不利的听力条件下，挑战比本地听众面临的挑战。但是，如果他们被认为熟练 英语，通常是开发出正常听力的非本地儿童，在学校没有住宿。 提供给有听力损失的非本地儿童提供的干预服务与他们的干预服务相同 本地同龄人，即使对听力损失对任何对任何人的言语交流的影响知之甚少 非本地人口。 拟议的研究项目的具体目的是在SL2中建立语音感知的基础 听力正常（AIM 1）和听力损失（AIM 2）的听众。通过比较语音感知能力 成人和儿童本地英语听众和SL2听众，有无听力损失，每个人都在 AIM将评估听众语言背景，听力状态的个人和阴谋影响 以及常见的音素感知年龄，通常会遇到具有挑战性的听力环境。使用 语音材料在上下文提示，自上而下和自下而上的处理的角色上有所不同 将被检查。将使用一种新方法对数据进行分析，该方法专门量化 关于辅音混乱模式的上述因素。 作为这项拟议的研究的一部分获得的数据将作为确定语音差的基础 SL2听众中的感知是由于语言背景或听力损失所致。反过来，这将有一个 对所提供的服务的评估过程，学术成果和成本效益的积极影响 在《残疾人教育法案》中，非英语儿童的非英语儿童并帮助他们成功 在学术和经济上。拟议研究的这一重要方面也与 2020年健康人中的“听力和其他感觉或沟通障碍”的目标。
