大多数关于第二语言阅读理解的研究表明，98%的词汇覆盖率可以提供足够的书面语篇理解。这个数字已经转移到听力理解，并已被用来设定词汇量的目标，为第二语言学习者。本研究直接调查听力理解中的覆盖率，以确定这种迁移是否合理。四个口语非正式的叙事段落的覆盖范围进行了操纵，和参与者（36名母语和40名非母语人士）的事实信息的听力理解进行了测量。结果表明，大多数本地和非本地的参与者可以充分理解的口语文本只有90%的覆盖率，虽然非本地人在这个水平上表现出相当大的变化。在95%的覆盖率下，非本地参与者也表现出相对较好的理解能力，但差异要小得多。根据95%的覆盖率，语言使用者需要知道2,000至3,000个单词家族才能充分理解听力，而Nation（2006）根据98%的数字计算出6000至7000个家族。
Most research on L2 reading comprehension has indicated that 98 per cent lexical coverage provides adequate comprehension of written text. This figure has been transferred to listening comprehension and has been used to set vocabulary size targets for L2 learners. This study directly investigates coverage in regard to listening comprehension, to determine whether such transfer is reasonable. The coverage of four spoken informal narrative passages was manipulated, and participants’ (36 native and 40 non-native speakers) listening comprehension of factual information was measured. Results showed that most native and non-native participants could adequately comprehend the spoken texts with only 90 per cent coverage, although the non-natives showed considerable variation at this level. At 95 per cent coverage, non-native participants also demonstrated relatively good comprehension, but with much less variation. Based on a 95 per cent coverage figure, language users would need to know between 2,000 and 3,000 word families for adequate listening comprehension, compared with Nation’s (2006) calculation of 6,000–7,000 families based on a 98 per cent figure.
