Since diphthongs are two sounds that are smoothly combined into one, it is important to pronounce them correctly, so as not to confuse them with regular vowels. Here are some important rules to help you deal with them:
1️⃣ Pronounce smoothly, without pauses
When you pronounce a diphthong, imagine that the two sounds should come together "smoothly," like two cool friends who can't part. For example, in the word ride [raɪd], you start with "a" but don't stop there, but go straight to "y". This means you can't pause, otherwise you won't say ride, but something like ra-ayd, and that would be wrong.
2️⃣ Don't forget the second sound
Sometimes it's tempting to say just the first sound and that's it. But if you forget the second sound, you can change the word altogether. For example, if you forget the "u" in the word go [ɡəʊ], you will get not "go" but "gae", and that's not the same! So always confidently bring the diphthong to the end.
3️⃣ Looking at the letters but thinking about the sounds
Or, more accurately, "don't judge by the letters." The letters are like clues, but the sounds themselves may be a little different. For example, in the word ear in British English, the diphthong [ɪə] will sound like i-e (and in the American version, just i - [ɪr]). It's important not to look at the letters, but to focus more on the sounds, because they can vary greatly from accent to accent.
4️⃣ Sometimes a diphthong turns into a regular sound
Diphthongs can sound different in different accents. For example, if you hear the word tour, in British English it will be with a diphthong [ʊə], like u-e. But in some accents, like American English, it might just sound like [ɔː], as in the word more. It's a cool feature of the language - it changes depending on where you are.
