Vowel sounds in English are necessary for communicating seamlessly and confidently. They contribute to the rhythm that influences a native speaker's accent, as well as constituting grammar and intonation.

For non-native speakers who aren't familiar with all English vowel sounds and how they work, speaking fluently might be quite a challenge. This is because English vowels make up a huge chunk of the language’s components, despite being composed of just five letters. Hence, understanding them is a significant step towards achieving fluency and clarity in your speech.

In this guide we'll explore vowel sounds in English language with examples to help non-native speakers master their English vowel pronunciation. By the end of this article you'll be equipped with the right knowledge to bring you several steps closer to speaking like a native.

What is a Vowel Sound?

Vowels are speech sounds made without blocking airflow in the throat. Unlike consonants, we produce vowels by letting air flow freely from our lungs. Vowels are important in English because they carry the main pitch and volume of speech. They are like the musical core of a syllable, making speech sound more melodic.

‍

How Many Vowel Sounds are there in English?

There are 20 vowel sounds in the English language. Many people may be familiar with the five vowel letters that make up these 20 vowel sounds. These letters are A, E, I, O, and U.

However, you may find it strange that some consonants also produce vowel sounds. This is because there are no obstructions in the vocal tract when we use them in a certain way. An example of a consonant like this is the Y sound.

‍

Classes of Vowel Sounds

We can categorize all vowel sounds in English into several classes based on characteristics such as their duration and pitch. Be that as it may, we typically have the following categories of vowel sounds.

‍

Pure Vowels (Monophthongs)

These are vowel sounds that maintain fixed tongue and lip positions throughout their articulation. This means that they do not exhibit any significant change in quality or position while being produced. Pure vowels in English include:  

"EE" or /i/

The tongue is high and at the front of the mouth. Example: "fleece."

‍

"EH" or /ɛ/

The tongue is positioned towards the front of the mouth. Example: "bet." 

‍

"AH" or /ɑ/

The tongue takes a low position at the back of the mouth. Example: "father." 

‍

"AW" or /ɔ/

The tongue is in an open position, and the lips are rounded. Example: "thought."

‍

"OH" or /oʊ/

The tongue is in the middle of the mouth, and the lips are rounded. Example: "goat." 

‍

"OO" or /u/

The tongue is high and at the back of the mouth, with rounded lips. Example: "goose."

‍

"U" or /ʊ/

The tongue is near the back but not as high as "OO." Example: "foot." 

‍

Diphthongs

Diphthongs are like two vowels in one. They are complex vowel sounds in which the tongue glides or moves from one vowel quality to another within the same syllable. Unlike pure vowels which have a single, stable tongue and lip position throughout their articulation, diphthongs involve a transition from one vowel sound to another. The following is a list of commonly used diphthongs in English: 

"EY" or /eɪ/‍

Keep your lips spread toward your ears. Move your jaw from a slightly open to a more closed position. Example: "day."

‍

"ai" or /aɪ/

Move your jaw from open to almost closed. Then spread your lips slightly toward your ears. Example: "time."

‍

"OY" or /ɔɪ/

Let your lips move from a little rounded to spread. Your jaw will be going from a more open shape to a more closed shape. Example: "coin."

‍

OW or /aʊ/

Let your lips move from a little spread to rounded. Your jaw will also go from a more open shape to a more closed shape. Example: "house."

‍
‍

Long Vowel Sounds

Long vowels are like the marathon runners of the vowel world. This is because they last a bit longer in your speech, and their tongue and mouth positions are specific. There are several long vowel sounds in English, including: 

"EE" or /i/

Pronounced with the tongue high in the front of the mouth. Examples: "see," "tree," "me."

"OO" or /u/

Pronounced with the tongue high and back in the mouth. Examples: "blue," "mood," "food." 

Short Vowels

Short vowel sounds are vowel sounds in English that are pronounced for a relatively shorter duration compared to long vowels. In English, there are five primary short vowel sounds. The short vowel sound often appears in one-syllable words or in the stressed syllables of longer words. Short vowel sounds are typically represented by a single vowel letter.

"AA" or /æ/

The tongue is low and at the front of the mouth. The lips are unrounded. It's a short, low-front vowel sound. Example: "cat."

"EH" or /ɛ/

The tongue is in the middle of the mouth, toward the front, and the lips are unrounded. It is a short, mid-front vowel sound. Example: "red."

"IH" or /ɪ/

The tongue is near the front but not as high as /iː/. The lips are also unrounded. It's a short, near-high front vowel sound. Example: "bit."

"AH" or /ɑ/

The tongue is positioned low and towards the back of the mouth. The lips are usually unrounded. Example: "hot."

"UH" or /ʌ/

The tongue is in a mid-central position and the lips are unrounded. It's a short, mid-central vowel sound. Example: "cup."

Consonant Letters as Vowels: The Y Sound

Remember we mentioned earlier that some consonant letters will produce vowel sounds, depending on how we use them? One such sound is the "Y" sound. We know this might be a little tricky, but it's really not so hard to identify a vowel sound. This is because there are rules that determine its usage:

‍

• When "y" appears at the end of a word or syllable and is followed by a consonant, it typically functions as a vowel, like in the words "sky" ("aɪ") and "happy" ("EE")
• In some words, "y" is the sole vowel in a syllable and represents a vowel sound. For example, "myth." The "y" in "myth" is the only vowel in the syllable and represents the "IH" sound, a vowel sound.

Why Vowel Sounds Are Important to Speak Like a Native

‍

Vowel sounds in English are important for achieving native-like pronunciation for the following reasons.

‍

Syllable Stress and Word Meaning

Vowel sounds play a vital role in determining which syllables in words we should stress or emphasize. The placement of stress in a word can change its meaning, so mastering vowel stress is essential for clear communication. For example, "bit" and "beat" differ only in their vowel sound ("IH" vs. "EE").

Natural Fluency

Like we mentioned earlier, vowel sounds contribute to the rhythmic flow of speech. Native English speakers use vowel sounds naturally and effortlessly. Hence, to sound like a native speaker, it's essential to mimic their vowel pronunciation. Watch how natural the rhythm is in the speech of native American business magnate Bill Gate in this video clip below: 

Accent Reduction

For non-native English speakers, the English language vowel sounds help reduce the accent evident in their speech. Accurate vowel pronunciation can help make your speech sound more neutral and clear. This in turn allows for effective communication, as more people can easily understand you. Compare Bill Gates’s speech in the previous video with that of the non-native speakers in this video below. 

Notice how distinct they both sound?

How to Master Vowel Sounds in English

To master the different vowel sounds in English, consider the following methods.

‍

Consult Speech Experts

Embrace the resources at your disposal and consult professional coaches or pronunciation apps that specialize in language training. Many of these expert platforms offer interactive exercises and audio guides to help you perfect vowel sounds in various contexts.

‍

Shadow Reading 

To refine your vowel pronunciation, consider practicing shadow reading on your own. Shadow reading involves speaking along with audio and visual materials, gradually refining your vowel articulation, intonation, and rhythm. For a start, you can begin with the list of English vowel sounds with examples we have provided in this article. Also, listen to native speakers often and try to mimic their pronunciation.

‍

Minimal Pair Exercises

It is easy to mistake many vowel sounds in English because they can be highly interrelated—for example, the short and long vowels "IH" and "EE" as in "sit" and "seat." Minimal pairs are words that differ by only one sound. Therefore, you want to engage in minimal pair exercises to distinguish between similar vowel sounds. This practice sharpens your ability to perceive and produce subtle sound distinctions.

‍

Embrace Tongue Twisters

There are diverse ways that you can actively learn vowel sounds. Tongue twisters are a great way to start because they're a fun and effective way to practice. Repeating these phrases not only hones your pronunciation but also enhances your fluency. Try the tongue twisters below:

"She sells seashells by the seashore."

"A black cat sat back to back with a white cat and made a nice couple."
