本研究探讨了年龄相关的差异，在使用动态声学信息（共振峰转换的形式），以确定元音质量的CVC。两个版本的61个自然产生的，常见的，单音节的英语单词被创建：一个控制版本（未修改的整个单词）和一个沉默的中心版本（其中约62%的中间元音被替换为沉默）。一组听力正常的年轻人（19-25岁）和老年人（61-75岁）识别出了这些标记。研究发现，老年受试者比年轻受试者在识别中间元音和初始和最后的辅音在沉默的中心条件下显着较差。这些结果支持了一个假设，年龄相关的递减处理能力的动态感知线索的感知元音质量。
This study examined age-related differences in the use of dynamic acoustic information (in the form of formant transitions) to identify vowel quality in CVCs. Two versions of 61 naturally produced, commonly occurring, monosyllabic English words were created: a control version (the unmodified whole word) and a silent-center version (in which approximately 62% of the medial vowel was replaced by silence). A group of normal-hearing young adults (19–25 years old) and older adults (61–75 years old) identified these tokens. The older subjects were found to be significantly worse than the younger subjects at identifying the medial vowel and the initial and final consonants in the silent-center condition. These results support the hypothesis of an age-related decrement in the ability to process dynamic perceptual cues in the perception of vowel quality.
