Diphthongs
The diphthongs are long vowels – as has already been explained – in which there is a noticeable movement of the tongue. In English the movement of the tongue has three possible directions: either higher towards the front of the roof of the mouth, that is, in the general direction towards the / I / or / i: / vowel; or higher towards the back, that is, in the general direction towards the / U / or / u: / vowel; or towards a central area, that is, in the general direction of the / V / or / 3: / vowel. These three directions are called front closing, back closing, and centring, respectively.
There are three front closing diphthongs in Southern English Standard Pronunciation; they occur in the following words and name: lake, like and Lloyd.
In the first one, lake, the tongue does not move a great deal, but you can nevertheless feel the movement as you imitate the vowel sound by itself "a….e". Its symbol is a double one, indicating the positions of the tongue at the beginning and at the end of the movement: / eI /. The [ e ] indicates a tongue position a little closer than the English / e / and more like the vowel in the French word thé (German Tee, etc). And the second part [ I ] indicates the position of the tongue at the end of the diphthongal movement.
Say the vowel slowly, to give yourself time to feel the movement of the tongue: [ eeeII ]. Thus, lake is transcribed
l e I k
You can now transcribe: bake, take, cake, make, sake, hake, wake, rake

In the North of England, Scotland and Wales, an alternative standard pronunciation is heard, in which there is no diphthongal movement at all, but a long monophthong – just like the vowel in the French word thé, German Tee, etc. This vowel would be transcribed as / e: /. Listen to it in the following few examples:
| lake | bake | take | great/grate | brake/break | stake/steak | Wales |
| /le:k/ | /be:k/ | /te:k/ | /gre:t / | /bre:k / | /ste:k / |
The second front closing diphthong appears in the word like. The symbol has already been mentioned: / aI /, which indicates a beginning position of the tongue like the / æ / and an ending like / I /. Say the word I / eye / aye in slow motion again: / aaaII /. Thus like is transcribed
l a I k
An easy way to draw the [ a ] symbol is to start at the top
left point and draw a rising curve to the right followed immediately by a steep
descent. Then you return halfway up the descent and draw a rising curve to the
left, and complete a circle to the base of the original descent
The homophones I, eye, aye are transcribed simply as / aI /.
Now you can transcribe: pike, bike, wipe, bite, wide, rhyme, nice

and these: lie, tie, die, pie, my, sty, cry, why, spry

and these with < igh >: high, light, bright, might, plight, height, tight

rite / write / right / wright ____
And these names: Mike, Di, Diane, Clive ___________________________
The third front closing diphthong occurs in the name Lloyd. In this case, not only does the tongue move, but the lips change shape too. The tongue moves from the position for the / O: / vowel to the position for the / I /. Thus, the symbol is / OI / and Lloyd is transcribed
l OI d
You can now transcribe: void, voice, noise, coin, quoit

There are just two back closing diphthongs: they occur in the words load and loud.
The first one, as in load, has a number of variations, but the main one in Southern English Standard Pronunciation has the tongue beginning in a central position and finishing like / U / or / u: /. The IPA symbol for the initial position of the tongue is like an upturned, inverted < e >: [ @ ]; this symbol is called shwa. To draw it, you start from the top left point, draw a reverse < c > symbol, and then loop back to the middle.

The whole symbol is / @U /. Load is thus transcribed as
l @U d
Now you can transcribe: toad, oats, boat, goat, float, gloat, bloat, roam

and the words: go, foe, low, slow, snow, grow

and the words: own, stone, bone, poke, rogue, stove, stroke, comb

Now the homophones rode / road ____
There is an important variation to the / @U
/ vowel in Southern English Standard Pronunciation, before the consonant / l
/. In this case, the tongue begins in the position for the / Q
/ vowel, and moves to / U
/. Listen to the two pronunciations of the word OLD: the standard
/ @U l d / and the
alternative / QU
l d /. This variation in the pronunciation of the vowel occurs only before
the consonant / l / in the same syllable. Transcribe the two versions of the
following words: cold, bolt, toll
____________________________________

and the homophones: hole / whole ____ ____
In addition to this variation in Southern English Standard, a quite different sound to this vowel is heard in Northern English, Scottish and Welsh Standard pronunciations and sounds like the long monophthong in the French word chaud (‘hot’), German so, Welsh lôn. It is transcribed in IPA as the letter <o> with length marks: / o: /. Listen to the following few examples:
| load | go | stone | comb | stroke |
| /lo:d/ | /go:/ | /sto:n/ | /ko:m/ | /stro:k/ |
The other back closing diphthong, as in loud, has a tongue movement which begins close to the beginning of / aI / but moves in the direction of / U / or / u:/. Thus its symbol is / aU / and loud is transcribed as
l aU d
In some descriptions, the other kind of <a> letter is used, but in practical terms, this makes very little difference in English.
Now transcribe: proud, cloud, crowd, scout, sprout, house, found, count

Notice the two pronunciations of these homographs, which rhyme either with prow or with crow: transcribe the two possibilities

Finally, the three centring diphthongs, which appear in the words, leer, lair and moor. In the first case, the tongue begins near the / I / or / i: / position and moves to the central area; the symbol is a combination of / I / and shwa: / I@ /. Thus, leer is transcribed
l I@
And now you can transcribe: ear, gear, near, rear, mere, sneer, queer, beard

and the homophones: peer / pier ____
The word YEAR has two pronunciations; listen and transcribe them both: year.
____ ____
Transcribe the names: Nia, Ian / Iain ____ ____
The second centring diphthong, as in lair, has the tongue in the position for the vowel / e / before it moves to the central area. The symbol is a combination of / e / and shwa: / e @ /. Thus lair is transcribed
l e @
When we first introduced the short vowel / e /, as in leg, we noted that some dictionaries employ the more familiar letter < e > of the Roman alphabet; those dictionaries also employ that letter in the transcription of this diphthong, as / e@ /.
Using the Greek letter / e / and schwa / @ /, transcribe:
air, dare, care, rare, square, prayer _________________________________
and the homophones fair / fare ____
and the two pronunciations of the homograph TEAR; transcribe them both.
____ ____
A noticeable change in the pronunciation of this vowel is taking place in England and Wales, particularly among the younger generation who otherwise speak with a standard accent; the diphthongal pronunciation is giving way to a long monophthongal / e : /. Listen to the difference between the traditional diphthong and this modern variation in the word LAIR: / l e @ / and / l e : /. Here are some more examples; transcribe them in both ways:
dare, square, care ____ ____ ____
and the name Clare / Claire ____ ____
Compare and transcribe these pairs of words:
The third centring diphthong, as in moor, has the tongue in the position for
/ U /, before it moves to the central area. The symbol is a combination of / U / and / @ /: / U@ /. Thus, moor is transcribed
m U@
You can now transcribe: poor, tour, boor, dour _____________________
However, there is a very strong tendency among the younger generation to replace this diphthong entirely – mainly by substituting it with the long monophthong / O: /. Thus moor becomes homophonous with more, poor with paw / pour / pore, tour with tore, and boor with bore. Similarly the word SURE is now much more commonly pronounced as homophonous with shore, rather than with the diphthong / U@ /.
However, the alternative pronunciation of dour does not follow this pattern; it is not / d O: / (‘door’), but / d aU @ / and produces a homophone with DOWER.
In rhotic accents, the centring diphthongs do not exist as such, since the final letter < r > is pronounced. In these accents the words leer, lair and moor are pronounced with an equivalent short vowel and a final / r / as / l I r /, / l e r / and / m U r /.
