-# 1.2 音素(Phonemes)
+# # 1.2. 音素(Phonemes)
在自然语音中,不可继续分割的组成部分被称为**音素**(phonemes)。英语的音素分为**元音**和**辅音**。
In natural speech, indivisible sound segments are referred to as *phonemes*. English language categorizes these phonemes into two types: *vowels* and *consonants*.
-## 1.2.1 元音(Vowels)
+英文的**音素**用**音标**标注其发音。
-英语总计约有 20 个**元音**。
+In English, **phonemes** are annotated by **phonetic symbols** to indicate pronunciation.
-English approximately has 20 *vowels*.
+遗憾的是,英文音标标注方式并不统一。我们在这里采用了 [Cambridge English Pronouncing Dictionary](https://dictionary.cambridge.org/pronunciation/) 的音标标注体系。
-元音可以被分为短元音(*short vowels*)和**长元音**(*long vowels*);与此同时,它们也可以分为**单元音**(*monophthongs*)和**双元音**(*diphthongs*)。
+Unfortunately, there's no universal standard for English phonetic notation. Here, we use the notation system from the [Cambridge English Pronouncing Dictionary](https://dictionary.cambridge.org/pronunciation/).
-Vowels can be classified into *long* and *short* vowels, or alternatively, they can also be grouped as *monophthongs* and *diphthongs*.
+> [!Note]

+> CEPD 的英式英语的音标是 D.J. 音标体系;而它的美式英语的音标采用的是国际音标体系(IPA);其详细说明请参考 CEPD 的官方网址[^1]:

+> The phonetic notation for British English in CEPD uses the D.J. system, while for American English, it adopts the International Phonetic Alphabet (IPA). For a detailed explanation, please refer to the official CEPD website:

-| Monophthongs | | Diphthongs |
-| ------------ | ---------------------------- | --------------------------------------- |
-| Short vowels | `ʌ` `e` `ə` `ɪ` `ʊ` `ɒ` | |
-| Long vowels | `ɑː` `æ` `əː` `iː` `uː` `ɔː` | `aɪ` `eɪ` `ɔɪ` `aʊ` `oʊ` `eə` `ɪə` `ʊə` |
+## 1.2.1. 元音(Vowels)
-严格意义上来讲,`æ` 是半长元音,即,它比长元音短一点,但比短元音长一点。
+| Vowels | Examples |
+| ------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| `ʌ` | c**u**p `/kʌp/` |
+| `ɑː` | f**a**ther `/ˈfɑː·ðɚ/` |
+| `e` | h**ea**d `/hed/` |
+| `æ` | h**a**t `/hæt/` |
+| `ə` | **a**bove `/əˈbʌv/` |
+| `ɚ` | moth**er** `/ˈmʌð·ɚ/` |
+| `ɝː` | b**ir**d `/bɝːd/` |
+| `ɪ` | sh**i**p `/ʃɪp/` |
+| `iː` | sh**ee**p `/ʃiːp/` |
+| `i` | happ**y** `/ˈhæp·i/` |
+| `ɔː` | h**or**se `/hɔːrs/` |
+| `ʊ` | f**oo**t `/fʊt/` |
+| `uː` | bl**ue** `/bluː/` |
+| `u` | sit**u**ation `/fʊt/` |
+| `eɪ` | d**ay** `/deɪ/` |
+| `aɪ` | **eye** `/aɪ/` |
+| `ɔɪ` | b**oy** `/bɔɪ/` |
+| `oʊ` | n**o**se `/noʊz/` |
+| `aʊ` | m**ou**th `/maʊθ/` |
+| `ɪr` | ear `/ɪr/` |
+| `er` | h**air** `/her/` |
+| `ʊr` | p**ure** `/pjʊr/` |
+| `aɪr` | f**ire** `/faɪr/` |
+| `aʊr` | **hour** `/aʊr/` |
-To put it strictly, `æ` is a mid-length vowel. That means it's a bit shorter than long vowels but longer than short vowels.
+**注**:这个列表中,没有英音 `ɒ` 的对应音 `ɑ`,比如,*hot* `/hɑt/`。在 CEPD 中,*hot* 直接被标注为 `/hɑːt/`,实际上,*hot* 中的 `ɑ` 并没有那么长,虽然它比其它短元音相对更长一些。
-## 1.2.2 辅音(Consonants)
+**Note**: In this list, the American English counterpart to the British English sound `ɒ`, as in *hot* `/hɑt/`, is not included. In CEPD, *hot* is directly marked as `/hɑːt/`. In reality, the `ɑ` sound in *hot* is not that long, although it is relatively longer than other short vowels.
-英文总计 28 个辅音。
+## 1.2.2. 辅音(Consonants)
-English approximately has 28 *consonants*.
+| Consonants | Examples |
+| ---------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| `p` | **p**en `/pen/` |
+| `b` | **b**ook `/bʊk/` |
+| `t` | **t**own `/taʊn/` |
+| `t̬` | cu**tt**ing `/ˈkʌt̬·ɪŋ/` |
+| `d` | **d**ay `/deɪ/` |
+| `k` | **c**at `/kæt/` |
+| `g` | **g**ive `/ɡɪv/` |
+| `f` | **f**ish `/fɪʃ/` |
+| `v` | **v**ery `/ˈver·i/` |
+| `s` | **s**ay `/seɪ/` |
+| `z` | **z**oo `/zuː/` |
+| `θ` | **th**ink `/θɪŋk/` |
+| `ð` | **th**is `/ðɪs/` |
+| `ʃ` | **sh**e `/ʃiː/` |
+| `ʒ` | vi**si**on `/ˈvɪʒ·ən/` |
+| `h` | **h**and `/hænd/` |
+| `tʃ` | **ch**eese `/tʃiːz/` |
+| `dʒ` | **j**ump `/dʒʌmp/` |
+| `m` | **m**oon `/muːn/` |
+| `n` | **n**ame `/neɪm/` |
+| `ŋ` | si**ng** `/sɪŋ/` |
+| `l` | **l**ook `/lʊk/` |
+| `r` | **r**un `/rʌn/` |
+| `w` | **w**e `/wiː/` |
+| `j` | **y**es `/jes/` |

+# 1.3. 口音(Accents)
+
+英语也许是地球上地方口音最多的语言,除了英式英语和美式英语之外,还有加大大英语、澳大利亚英语、苏格兰英语、新西兰英语…… 即便是在英国之内,也有很多不同的口音,甚至伦敦南部和东部的口音都有可能并不相同。同样,在美国,各个区域的口音事实上有很大区别。
+
+English may well be the language with the most regional accents on Earth. It's not just about British English and American English; there's also Canadian English, Australian English, Scottish English, New Zealand English, and so on. Even within the UK, there are countless different accents. You might find that the accent in South London is different from that in East London. Likewise, in the United States, accents can significantly vary depending on the region.

+In reality, heavy regional accents can even stump native English speakers. Check out this [YouTube link](https://www.youtube.com/watch?v=1jHfY0dDZxA) for a humorous example.

+很多人在学英语的时候,对口音的选择异常纠结。其实大可不必,只要想想你最能最常听到的口音是什么就可以了 —— 显然,对绝大多数人来说,在这个视听媒体格外发达的时代,人们更常听到的可能是美式英语。

+Many people find themselves particularly torn when deciding on an accent to adopt while learning English. However, it's not as big of a deal as it seems. Simply consider the accent you hear most frequently - it's clear that for the majority of people, in this age where audio and visual media are abundantly prevalent, the *American English* accent is perhaps the one most often heard.

-## 1.3.2. D.J. 音标(D.J. Phonetics)
-
-在上一节中,大致讲解英语音素的时候,所采用的实际上是 D.J. 音标体系 —— 不过,它最初是为了标注英式(标准)英语而设计的,无法完整标注美式英语发音。
-
-[Daniel Jones](https://en.wikipedia.org/wiki/Daniel_Jones_(phonetician)) 于 1917 年发布 *English Pronouncing Dictionary* (*EPD*, 英语发音词典),并在其后的多年里反复修订。最终它被剑桥接手,更名为 *Cambridge English Pronouncing Dictionary* (*CEPD*, 剑桥英语发音词典) 。*CEPD*于 1997 年发布第 *15* 版,与**国际音标**(IPA)统一,增加了一些符号用以同时标注美式发音。目前的 *CEPD* 已经是[第 *18* 版](https://www.cambridge.org/gb/cambridgeenglish/catalog/dictionaries/cambridge-english-pronouncing-dictionary-18th-edition)。
-
-## 1.3.3. 国际音标(IPA)
-
-国际音标(IPA)最初由法国语言学家 Paul Passy 带领的一群英法语言教师于 1886 年设计并提出。此后经过多次改版,以下是 2020 年的 IPA 官方字符集:
-
-
-
-CEPD (18^th^) 实际上采用的就是 IPA。在我们的教程里,采用的音标,是 [Cambridge Pronouncing Dictionary](https://dictionary.cambridge.org/pronunciation/) 的**美式注音**。音标符号详解可以参照 CEPD 的官方链接:

-
-## 1.3.4. 美式英语音素及音标(American Phonemes and Phonetics)
-
-英语的地方口音绝大多数体现在**元音**的不同。
-
-以下是美式英语的元音(及其重新分类):
-
-| Monophthongs | | Diphthongs |
-| ---------------- | ------------------------ | --------------------------------------- |
-| Short vowels | `ʌ` `e` `ə` `ɚ` `ɪ` `ʊ` | |
-| Half long vowels | `æ` `i` `ɑ` | |
-| Long vowels | `ɑː` `ɝː` `iː` `uː` `ɔː` | `aɪ` `eɪ` `ɔɪ` `aʊ` `oʊ` `er` `ɪr` `ʊr` |
-
-不太一样的地方主要在于:
-
-* `æ` 在美式英语里是**半长元音**,即,比短元音长一点,比长元音短一点。式比较一下 *apple* `/ˈæp·əl/` 的英式发音和美式发音。
-* `ə`
- * 非儿化短元音 `ə`,在美式英语中,被称作 *schwa*,非重读央元音 —— 即,只出现在非重读音节中。比如,*ago* `/əˈɡoʊ/` 或者 *develop* `/dɪˈvel·əp/`。在 CEPD 里,非重读音节的 `ɪ` 往往都直接被标注为 `ə`。比如,*individual*,英式音标为 `/ˌɪn·dɪˈvɪdʒ·u·əl/`, 但,美式音标是 `/ˌɪn·dəˈvɪdʒ·u·əl/`。
- * `ə` 儿化音版本被标注为 `ɚ`。比如,*harder* `/hɑːrdɚ/` 或者 *teacher* `/ˈtiː·tʃɚ/`。
- * `ə` 对应的长元音 `əː` 写作 `ɜː`;但,在美式英语中,这个长元音总是被儿化,所以写作 `ɝː`。比如,*server* `/ˈsɝː·vɚ/` 或者 *worker* `/ˈwɝː·kɚ/`。
-* `i`,在英语中其实有三个版本,短元音 `ɪ`,半长元音 `i`,以及长元音 `iː`。半长元音 `i` 常常出现在词汇末尾,比如,*city* `/ˈsɪt·i/`, *happy* `/ˈhæp·i/`。
-* 在美式英语中,短元音 `ɒ` 被读成半长元音 `ɑ`,在 CEPD 里干脆加上了长元音符号,比如,hot `/hɑːt/`。而长元音 `ɔː` 也常常被标注为 `ɑː`,比如,*water* `/ˈwɑː·t̬ɚ/`。但,美国人也不会把 *war* 读成 `/wɑːr/`,还是读作 `/wɔːr/` —— 只是比英式发音多了一个儿化的习惯。
-* 在美式英语中,双元音 `eə`、`ɪə`、`ʊə` 中的 `ə` 都会被儿化,所以都直接相应地被标注成了 `er`、`ɪr`、`ʊr`。
-* 另外,英式英语中还有两个**三元音**: `aɪə` 比如,*fire* `/faɪə/`;*hour* `/aʊə/`。在美式英语中,这两个三元音被简化为双元音的更为明显的儿化音,`aɪə` → `aɪr`,比如,*fire* `/faɪr/`, *hour* `/aʊr/`。
-
-来自辅音的主要区别是 `t`。
-
-在美式英语里,家在两个元音之间的 `t` 会被浊化,形成弹舌音,用 `t̬` 来标注,比如,*water*,英式发音是 `/ˈwɔː·tə/`,美式发音是 `/ˈwɑː·t̬ɚ/`。

+
+To sum up, it's an interesting feature of American English: the sound `ʌ` actually has three versions. You've got the short vowel `ʌ` as in *but* `/bʌt/`, the half-long vowel `ɑ` as in *hot* `/hɑt/`, and the long vowel `ɑr` as in *card* `/kɑːrd/`.
