-Note that `/ʌl/` doesn't have the schwa (`ə`) sound added, since `/ʌ/` and `ə` are already very similar. For instance, *ultimate* `/ˈəltəmət/`<span class="speak-word-inline" data-audio-us-male="/audios/us/ultimate-us-male.mp3" data-audio-us-female="/audios/us/ultimate-us-female.mp3"></span>, or *result* `/rɪˈzəlt/`<span class="speak-word-inline" data-audio-us-male="/audios/us/result-us-male.mp3" data-audio-us-female="/audios/us/result-us-female.mp3"></span>. Also, pay attention to `/iːl/` in natural speech. For example, while *reveal* is indeed pronounced as `/rɪˈviːəl/`<span class="speak-word-inline" data-audio-us-male="/audios/us/reveal-us-male.mp3" data-audio-us-female="/audios/us/reveal-us-female.mp3"></span>, with the schwa sound, *revealing* is pronounced as `/rɪˈviːlɪŋ/`<span class="speak-word-inline" data-audio-us-male="/audios/us/revealing-us-male.mp3" data-audio-us-female="/audios/us/revealing-us-female.mp3"></span>, without the schwa. This change might be due to the fact that the `l` sound has been moved to form a third syllable with `ɪŋ` as `/lɪŋ/`.

 `l` 在语言学里有个专门的称呼，叫做**音节辅音**，就是因为它的发声动作如果完整的话，前面就会自然附加着一个轻微的元音 `ə` 的音色。比如，*little* `/ˈlɪtl̩/`<span class="speak-word-inline" data-audio-us-male="/audios/us/little-us-male.mp3" data-audio-us-female="/audios/us/little-us-female.mp3"></span> —— `l` 下面多出的那一个点 `l̩` 的意思是说，这里的 `l̩` 是个**音节辅音**，相当于 `/ᵊl/`…… 当然，很多词典干脆就直接标注成了 `/ˈlɪtᵊl/` 或者 `/ˈlɪtəl/`。CEPD 里标注的是 `/ˈlɪt̬əl/`，因为 `t` 夹在两个元音之间，变成了弹舌音 `t̬`。
