Under natural conditions, listeners use both auditory and visual speech cues to extract meaning from speech signals containing many sources of variability. However, traditional clinical tests of spoken word recognition routinely employ isolated words or sentences produced by a single talker in an auditory-only presentation format. The more central cognitive processes used during multimodal integration, perceptual normalization, and lexical discrimination that may contribute to individual variation in spoken word recognition performance are not assessed in conventional tests of this kind. In this article, we review our past and current research activities aimed at developing a series of new assessment tools designed to evaluate spoken word recognition in children who are deaf or hard of hearing. These measures are theoretically motivated by a current model of spoken word recognition and also incorporate "real-world" stimulus variability in the form of multiple talkers and presentation formats. The goal of this research is to enhance our ability to estimate real-world listening skills and to predict benefit from sensory aid use in children with varying degrees of hearing loss.
在自然条件下,听众会利用听觉和视觉言语线索从包含多种变异来源的言语信号中提取意义。然而,传统的口语单词识别临床测试通常采用单一说话者以仅听觉呈现格式说出的孤立单词或句子。在多模态整合、感知归一化和词汇辨别过程中使用的更为核心的认知过程,可能导致口语单词识别表现的个体差异,而在这类传统测试中并未得到评估。在本文中,我们回顾了我们过去和当前的研究活动,旨在开发一系列新的评估工具,以评估聋或重听儿童的口语单词识别能力。这些测量方法在理论上受到当前口语单词识别模型的推动,并且还以多个说话者和呈现格式的形式纳入了“现实世界”的刺激变异性。这项研究的目标是提高我们估计现实世界听力技能的能力,并预测不同程度听力损失儿童使用感官辅助设备的益处。
