Schonell等人（1956）对澳大利亚英语口语的研究发现，2，000个单词家族提供了口语话语约99%的词汇覆盖率。在此基础上，学者们已经接受了大约2,000个词族提供的词汇资源，从事日常英语口语语篇。这项研究分析了一个现代口语语料库（CANCODE语料库），发现2,000个词族占不到95%的覆盖率。对CANCODE和英国国家语料库的口语部分进行了第二次分析，发现需要大约5，000个单词才能实现约96%的覆盖率。这些结果表明，更多的词汇是必要的，以从事日常口语话语比以前认为的。这意味着，作为口语/听力提高的一部分，更加重视词汇的发展是必要的。
The Schonell et al. (1956) study of Australian oral English found that 2,000 word families provided around 99 per cent lexical coverage of spoken discourse. Based on this, scholars have accepted that around 2,000 word families provide the lexical resources to engage in everyday spoken English discourse. This study analysed a modern spoken corpus (the CANCODE corpus) and found that 2,000 word families made up less than 95 per cent coverage. A second analysis was performed on the CANCODE and the spoken component of the British National Corpus, which found that around 5,000 individual words were required to achieve about a 96 per cent coverage figure. These results suggest that more vocabulary is necessary in order to engage in everyday spoken discourse than was previously thought. The implication is that a greater emphasis on vocabulary development is necessary as part of oral/aural improvement.
