四个实验，所有这些都集中在元音的持续时间，评估中国被试的生产和感知的对比/t/和/d/的最后位置的英语单词。在第一个实验中，元音持续时间被测量为最小对。刺激自然编辑beat-bead和bat-bad连续，其中元音持续时间变化在20毫秒的步骤，然后提交给母语为英语和汉语的受试者在强迫选择测试，在实验中使用的方法调整，并在模仿任务。在所有四个实验中，在童年时期学习英语的非母语者与母语者非常相似。另一方面，三组在成年后将英语作为第二语言学习的非母语者与母语者不同。晚学习者在以/d/结尾的单词中产生的元音明显长于/t/。然而，晚学者的元音持续时间差异比本族语者小得多，并且与英语中的外国口音程度显着相关。在两个感知实验中，晚学习者在几个方面不同于本族语者，在模仿任务中也是如此。的模式显着和不显着的组间差异，但不是数据为个别科目，是一致的假设，即L2（第二语言）生产的准确性是有限的，在L2的声音的感知表征的充分性。
Four experiments, all of which focused on vowel duration, assessed Chinese subjects' production and perception of the contrast between /t/ and /d/ in the final position of English words. Vowel duration was measured in minimal pairs in the first experiment. The stimuli in natural-edited beat-bead and bat-bad continua in which vowel duration varied in 20-ms steps were then presented to native English and Chinese subjects in a forced-choice test, in an experiment using the method of adjustment, and in an imitation task. The non-natives who learned English in childhood closely resembled native speakers in all four experiments. Three groups of non-natives who had learned English as a second language in adulthood, on the other hand, differed from the native speakers. The late learners produced significantly longer vowels in words ending in /d/ than /t/. However, the late learners' vowel duration differences were much smaller than the native speakers', and were correlated significantly with degree of foreign accent in English. The late learners differed from the native speakers in several ways in the two perception experiments, and also in the imitation task. The pattern of significant and nonsignificant between-group differences, but not data for individual subjects, was consistent with the hypothesis that L2 (second language) production accuracy is limited by the adequacy of perceptual representations for sounds in the L2.
