+# 3.1.7. `ɔ/ɔː`
+
+这一对元音在发声的时候，嘴唇动作非常明显，要在嘴唇形成一个小的圆形之后才开始发音。
+
+When pronouncing this pair of vowels, the lip movement is very noticeable. It's important to form a small circle with lips before beginning to vocalize.

+与英音相比，美音的 `ɒ` 会读得更长一点，听起来更像 `ɑ`。比如，*dog*, 英音是 `/dɒg/`, 美音却是 `/dɔːg/`；而 *God*, 英音是 `/gɒd/`，美音同样相对更长一点，`/gɔːd/` —— 有些词典（比如[朗文词典](https://www.ldoceonline.com/dictionary/dog)）为此直接添加了长音符号 `ː`。
+
+Compared to British English, the American pronunciation of `ɒ` is slightly *longer* and sounds more like `ɑ`. For instance, for the word *dog*, in British English, it's pronounced as `/dɒg/`, while in American English, it's pronounced as `/dɔːg/`. Similarly, for *God*, it's `/gɒd/` in British English, but in American English it's elongated to `/gɔːd/`. Some dictionaries, like the [Longman Dictionary](https://www.ldoceonline.com/dictionary/dog), directly add the lengthening symbol `ː` for this reason.
+
+另外，在重读音节里，`ɔː` 可能会被美国人儿化，读成 `ɔr` ，更像是双元音 `ɔər`。
+
+Additionally, in *stressed* syllables, `ɔː` might be rhotacized by Americans to sound like `ɔr`, resembling the diphthong `ɔər`.

+> D.J. 音标最初的时候短元音用 `ɔ`，长元音用 `ɔː`；但后来短元音 `ɔ` 开始使用笔划上闭口的 `ɒ`，而长元音依然使用带着长音符号且笔划上开口的 `ɔː`。
+>  
+> Initially, in the D.J. phonetic alphabet, short vowels used `ɔ`, and long vowels used `ɔː`. But later, the short vowel `ɔ` started being represented with a closing stroke on the upper part as `ɒ`, while the long vowel continued to use `ɔː` with the lengthening symbol and an open stroke on top.
