Diphthong Sounds


Hi there, in this video we are going to be
looking at the Diphthongs sounds. I am Colin Munro and this is the English Language
Club. Diphthongs are the sounds represented by the
symbols in red. There are 8 of them on the phonetic chart
and these are the main ones that you need to know about.
So what is a Diphthong? Well a Diphthong is a type of vowel sound that is made up of a
combination of two single vowel sounds but within the same syllable.
Each column is arranged according to the second sound in the Diphthong.
In the first column each sound ends with /ə/ /ɪə/ /ʊə/ /ʊə/ and /eə/ In the second column each sound ends with an /i:/ sound. /eɪ/, /ɔɪ/, and /aɪ/ And in the third column each sound ends with a /ʊ/ sound. /əʊ/ and /aʊ/ Remember that the key to pronunciation is
physical, and the Diphthongs are a combination of 2 sounds. So your mouth will change
position as you say the sound. Lets look at the monophthongs again so you can
see you what i mean. First of all lets look at /ɪə/.
This is a combination of /ɪ/ and /ə/, but it’s pronounced within one syllable, /ɪə/. The main physical difference between the sounds on the top row and the sounds on the second
row, is that your mouth should be a little more open for the second row sounds. So as you say /ɪə/ your mouth should open a little bit.
Starting on the /ɪ/ and finishing on the /ə/ /ɪə/ As in the words; “Year”, “Here” and “Really” Lets look at the next one This is a combination of /ʊ/ and /ə/ … /ʊə/
Again your mouth should open a little as you go from the first sound to the second sound. Starting on the /ʊ/ and finishing on the /ə/ /ʊə/ As in the words; “Our”, “Power” and “During” Now we have a combination of /e/ and /ə/ /eə/. This time both the vowels are on the same row so the mouth does not open or close, the main differenceis the shape of our lips and the origin of the sound in our throat. Starting on the /e/ and finishing on the /ə/ /eə/. As in the words;
“There”, “Where”, and “Parent” Moving onto the second column, now each sound
ends with the vowel sound /ɪ/ or /iː/. Because sometimes it is the longer /i:/ sound. In reality it is somewhere between the two, it depends on the word.
When we say the diphthongs sound in isolation, we will normally use the longer form. /eɪ/ /ɔɪ/ and /aɪ/ The first sound is /eɪ/ which
is a combination of /e/ and /ɪ/ or /i:/ This time we need to close our mouth a little
as we say the sound. Starting on the /e/ and finishing on the /ɪ/
or /i:/. /eɪ/ As in the words;
“They”, “Say” and “Make” The next sound is /ɔɪ/ this is a combination
of /ɔ:/ and /ɪ/ or /i:/. They are on different rows again but the shape
of our lips and the position of our tongue also change a lot because we are going from
the right all the way to the left. Going from rounded lips to unrounded. Starting on the /ɔ:/ and finishing on the /ɪ/ or /i:/ /ɔɪ/ As in the words;”Point”, “Boy” and “Oil” The next sound is /aɪ/ which is a combination of /ɑ:/ and /ɪ/ or /i:/. Now we are going from the bottom row to the top so our mouths start wide open and
close as we say the sound. /aɪ/ Starting on the /ɑ:/ and finishing on the
/ɪ/ or /i:/. /aɪ/ As in the words;
“I”, “By”, and “Time” The next sound is /əʊ/ this is a combination
of /ə/ and /ʊ/ or /uː/. The main difference here is the shape of the
lips, rounding a little as we say the sound. /əʊ/ Starting on the /ə/ and finishing on /ʊ/ or /uː/. /əʊ/ As in the words;
“Go”, “Know” and “Only” The next sound is /aʊ/ this is a combination
of /æ/ and /ʊ/ or /u:/. Now our mouth is closing and the shape of
the lips is changing at the same time, rounding a little as we say the sound, /aʊ/ Starting on the /æ/ and finishing on the /ʊ/ or /u:/ /aʊ/ As in the words;
“Out”, “How” and “Down” So that is all the diphthongs sounds. Thanks for

  12. Reynold Gooding says:

    I suspect that this is an important lesson;however I believe that I will never learn it.Are those English symbols ,like a,e,i,o and u or these russion or german or some other language I am seeing horseshoe symbols ,the letter three ,reverse letters.I am even seeing the letter "c",but no "o".Why can't someone explain diptongs using the English vowels as written in all English books?And the strange thing is that no one seems to recognise the difficulty those weird symbols are causing.Why can't someone explain where they came from and how they are pronounced?We do not have that difficulty with Spanish vowels.In Spanish there are three strong vowels;viz A E and O and two weak vowels:I and U.Whenever a weak vowel is combined with a strong vowel or with another weak vowel a diptong is formed resulting in one sound in the syllable;and whenever two strong vowels are iside by side they form separate syllables.Why can't English be as simple like that?

    Riiiiiight. Let’s pronounce O (oh).

    Mr. Softunderbelly: Start with u (short oo, as in book) and end with u (short oo, as in book again) – OH. LOLOL!!! As not only a native speaker but also a professional teacher I find this explanation of diphthongs utterly incredulous. Students of English, PLEASE DO NOT take this video as gospel! 🙂

  37. Basel Shishani says:

    Just a small peeve. When you started demonstrating individual diphthongs, you removed the diphthong chart off the screen and kept on the green chart. You should've kept the diphthong chart on so that the learner can compare the different voices.

    Sir reply me…plz

  62. Stephen Anon says:

    I wouldn't trust any pronunciation teacher that can't pronounce the word PRONUNCIATION. 1:20 in he calls it PRONOUNCIATION, which not only is not a word, but it's a mistake between producing a monophthong and a diphthong. In other words, this guy's pronunciation is wrong AND he's actually getting confused about the exact thing he's supposed to be teaching us about. Look up the word in any dictionary, UK or otherwise…

  63. James Quek says:

    Power is /pɑʊə/ and our is /aʊə/ 2:47
