PROJECT SUMMARY Infants who are hard-of-hearing (IHH) are at significantly increased risk for poor auditory development and speech perception (e.g., perceiving cat versus hat), despite early hearing detection and intervention. For infants with normal hearing (INH), the first year of life is a seminal period for refining speech perception abilities shaped by exposure to language. During this early developmental period, perceptual skills become more narrowly tuned to spectral and temporal features, or cues, that favor discrimination of behaviorally relevant information. Thus, early perceptual skill development is driven by the dynamic interplay between language experiences and the concurrent maturation of auditory sensory pathways. Because refinement of speech discrimination abilities depends on an infant's exposure to speech sounds, IHH are susceptible to atypical development during this period. What remains poorly understood is the impact of inconsistent auditory cue access and poor speech perception among IHH. There is a critical need to map auditory development among IHH and to understand the long-term impacts of auditory cue processing on speech perception abilities. Filling this need will lay the foundation for developing clinical tools that will aid in personalization of intervention strategies. Our overall objectives in this application are to 1) map the emergence of speech perception among IHH compared to a cohort of age-matched INH; 2) describe the effects of auditory speech cue access on speech discrimination in noise, and 3) to assess the relationship between attunement of speech perception and functional auditory skills. By comparing these groups at 3, 6, and 12 months of age, we can describe the extent to which maturation and experience contribute to the emergence and attunement of speech perception abilities. To document speech perception development, we will use scalp-recorded electroencephalography (EEG) measured in response to native and non-native speech sounds. Our hypotheses are: 1) INH will demonstrate attunement for vowel and consonant speech sounds, but IHH will not; 2) speech perception abilities measured at 12 months of age will be positively correlated with discrimination abilities; and 3) auditory development scores will be higher for infants who demonstrate attunement to English consonant sounds. Results will inform our understanding of speech perception and auditory skill development among IHH. Our long-term goal is to improve speech and language outcomes in children with hearing loss. This project is relevant to NIDCD's mission of understanding the mechanisms of hearing loss which impact the emergence of speech perception and functional auditory skill development.

项目摘要 听力障碍（IHH）的婴儿有明显增加听觉发展和不良的风险 尽管有早期的听力检测和干预，但语音感知（例如，感知到猫与帽子）。为了 患有正常听力（INH）的婴儿，生命的第一年是精炼语音感知能力的开创性时期 通过接触语言来塑造。在这个早期的发育时期，感知技能变得更加 狭义地调整为偏爱歧视行为相关的光谱和时间特征或提示 信息。因此，早期的感知技能发展是由语言之间的动态相互作用驱动的 经验和听觉感觉途径的同时成熟。因为演讲的完善 歧视能力取决于婴儿的语音传播，IHH容易受到非典型的影响 在此期间的发展。仍然不了解的是听觉提示不一致的影响 IHH之间的访问和言语不佳。迫切需要绘制听觉发展 IHH并了解听觉提示处理对语音感知能力的长期影响。填充 这种需求将为开发临床工具奠定基础，以帮助个性化干预 策略。 我们在本应用程序中的总体目标是1）映射IHH之间的语音感知的出现 与年龄匹配的INH队列相比； 2）描述听觉语音提示访问对语音的影响 在噪声中歧视，3）评估语音感知和 功能性听觉技能。通过在3、6和12个月大的时候比较这些组，我们可以描述 成熟和经验有助于语音感知的出现和调整 能力。为了记录语音感知的发展，我们将使用头皮录制的脑电图 （脑电图）响应天然和非本地语音的响应。我们的假设是：1）INH会 展示元音和辅音语音的调整，但不会； 2）语音感知 在12个月大时测量的能力将与歧视能力呈正相关； 3）听觉 对于表现出对英语辅音声音的调整的婴儿，开发分数将更高。 结果将为我们对IHH之间的语音感知和听觉技能发展的理解提供信息。我们的 长期目标是改善听力损失儿童的言语和语言结果。这个项目是 与NIDCD了解听力损失机制的使命有关 语音感知和功能性听觉技能发展。
