The term “Pacific Ocean” is notorious among English learners. Do you know why?
Each of the three C’s in this phrase are pronounced in a unique way. The first C, “PaC ific,” is pronounced with an S sound. The second, “PacifiC ,” sounds like a K. And the third, “OC ean,” sounds like “sh” in “share.”
For non-native speakers of English, these pronunciations are far from obvious. And there are endless examples in English where a word’s spelling does not clearly indicate how it should be pronounced.
Enter the International Phonetic Alphabet (IPA)—your secret weapon to mastering English pronunciation with precision and confidence.
The IPA chart is more than just a collection of strange symbols; it's a tool that can help you understand and produce every sound in the English language (and beyond). For English learners, especially those at a mid to advanced level, grasping the IPA can make the difference between good and great when it comes to pronunciation.
This guide will take you through everything you need to know about the IPA, from its structure to its practical applications, so you can use it to sharpen your pronunciation skills and guide your students toward clearer, more accurate speech.
Understanding the IPA What is the IPA?
The International Phonetic Alphabet (IPA) is a system of phonetic notation that was first developed in the late 19th century by linguists and phoneticians to create a standardized way to represent the sounds of spoken language.
Unlike the English alphabet, which is primarily used for writing, the IPA is designed specifically to capture the distinct sounds (or phonemes) that make up speech. Each symbol on the IPA chart corresponds to a unique sound, making it a universal tool that can be used to describe the pronunciation of any language, not just English.
The IPA's brilliance lies in its consistency. No matter where you are in the world or what language you speak, an IPA symbol represents the same sound.
For English learners, this means you can look at a word's IPA transcription and know exactly how to pronounce it, without the guesswork that often comes with English spelling.
Why the IPA Matters for English Learners
Pronunciation is often one of the biggest challenges for English learners. English is notorious for its irregular spelling and pronunciation rules, and many learners find themselves struggling to make sense of it all. This is where the IPA comes in.
Understanding the IPA allows you to see the exact sounds you're supposed to make, rather than relying on sometimes misleading spelling. For example, consider the words "though," "through," and "rough." These words all contain the letters "ough," but they are pronounced very differently. By learning the IPA symbols for these sounds, you can avoid confusion and improve your pronunciation accuracy.
Moreover, the IPA helps you fine-tune your accent by drawing attention to subtle differences between sounds that might not exist in your native language. For instance, many learners struggle with the difference between the English sounds /θ/ (as in "th ink") and /ð/ (as in "th is"). The IPA makes it easier to identify and practice these sounds, leading to clearer and more native-like speech.

Overview of the IPA Chart Layout
The IPA chart might look intimidating at first glance, but once you understand its structure, it becomes a powerful tool for language learning. The chart is divided into sections that correspond to different types of sounds: consonants, vowels, and other symbols.
Consonants are sounds made by obstructing the airflow in some way, such as by using your tongue, lips, or teeth. The consonants on the IPA chart are organized by two main factors: the place of articulation (where in the mouth the sound is made) and the manner of articulation (how the sound is produced).
Vowel sounds are produced without significant constriction of the airflow. They are organized on the IPA chart according to the position of the tongue (front, central, back) and the height of the tongue (high, mid, low), as well as whether the lips are rounded or unrounded.
The chart also includes symbols for additional sounds, such as clicks, tones, and intonation , though these are less relevant to English learners.
Grouping of Sounds
The IPA chart is designed to group similar sounds together, making it easier to compare and contrast them. For example, voiced and voiceless pairs (like /t/ and /d/, or /s/ and /z/) are placed next to each other on the chart. This arrangement helps you understand the subtle differences between sounds that might seem very similar at first.
For English learners, recognizing these groups is key to mastering pronunciation. Take the voiced vs. voiceless distinction, for instance. In English, the difference between words like "bat" and "pat" hinges on whether the sound is voiced (your vocal cords vibrate) or voiceless (they don't). By using the IPA you can learn to produce these sounds correctly, which can be particularly challenging if your native language doesn't make the same distinctions.
Navigating the IPA Vowel Chart Vowels in the IPA
Vowels are the heart of spoken language, and in English, they can be especially tricky. The IPA vowel chart is a map of all possible vowel sounds, organized by the position of your tongue and the shape of your lips.
Tongue Position
Vowel sounds are classified by where the tongue is in the mouth—front, central, or back.
For example, the vowel in "beat" (/iː/) is a front vowel, while the vowel in "boot" (/uː/) is a back vowel.
Openness
Another key aspect of vowel classification is the openness of the mouth during articulation. This is known as the openness or closeness of a vowel and helps distinguish between different vowel sounds.
Open vowels are produced with the mouth wide open, creating a larger space between the tongue and the roof of the mouth, as in the /ɑː/ sound in "father."
Mid vowels involve a partially open mouth, as in the /e/ sound in "bed" and the /ɔː/ sound in "thought."
Closed vowels are produced with the mouth nearly closed, leaving a small gap between the tongue and the roof of the mouth, as in the /iː/ sound in "see" and the /uː/ sound in "blue."
Lip Rounding
Vowels can also be classified by whether the lips are rounded or unrounded. Rounded vowels like /uː/ involve pursing the lips, while unrounded vowels like /iː/ do not.
Diphthongs
English is not only rich in individual vowel sounds but also in diphthongs —combinations of two vowel sounds within the same syllable. A diphthong starts with one vowel sound and glides into another, creating a smooth, continuous sound.
For example, the word "time" contains the diphthong /aɪ/, which begins with the vowel sound in "father" (/ɑː/) and glides into the sound in "sit" (/ɪ/).
Diphthongs aren’t explicitly shown on the IPA vowel chart because the chart focuses on single vowel sounds (monophthongs), which are the components of diphthongs. To transcribe a diphthong, you combine the symbols for the two vowels that form it.
The IPA Consonant Chart Understanding Consonant Sounds
Consonants are the building blocks of words, and the IPA chart helps you understand the full range of consonant sounds in English. The consonants on the IPA chart are organized by:
Place of Articulation This refers to where in the mouth the sound is produced.
For example, the sound /p/ is a bilabial sound, meaning it is made with both lips, while the sound /k/ is a velar sound, produced at the back of the mouth.
Manner of Articulation
This refers to how the sound is produced, such as whether the airflow is completely blocked (as in plosives like /p/ and /t/) or only partially blocked (as in fricatives such as /f/ and /s/).
Voicing
Voicing refers to whether the vocal cords vibrate during the production of the sound.
Voiced consonants include sounds like /b/ and /d/, while voiceless consonants include sounds like /p/ and /t/.
IPA Diacritics Diacritics might seem like the fine print of the IPA chart, but they are crucial for capturing the nuances of pronunciation.
These small symbols or marks are added to the main IPA symbols to indicate slight variations in how a sound is produced. For English learners, understanding diacritics can help you fine-tune your pronunciation, bringing you closer to sounding like a native speaker.
What Are Diacritics?
Diacritics are additional marks placed above, below, or next to an IPA symbol. They modify the sound that the symbol represents, providing more detail about how the sound is articulated.
While the basic IPA symbols give you the general sound, diacritics refine that sound, offering information on aspects like tone, nasalization, length, stress, and more.
In English, diacritics are particularly useful for indicating subtle pronunciation differences that might not be obvious from the base IPA symbol alone.
For example, the difference between an aspirated and unaspirated /p/ (as in "pat" vs. "spin") can be shown using diacritics.
Common Diacritics Used in English
Here are some of the most common diacritics you might encounter when studying English pronunciation:
Aspiration [ʰ]
In English, voiceless stops like /p/, /t/, and /k/ are often aspirated at the beginning of a word. The diacritic [ʰ] indicates that extra puff of air.
For example, the /p/ sound in "pat" is often aspirated, meaning there is a small burst of air after the sound is produced. This is represented by the diacritic [ʰ], so "pat" might be transcribed as [pʰæt].
Nasalization [˜ ]
Nasalization occurs when air flows through the nose during the pronunciation of a vowel. The diacritic [˜ ] shows that the vowel sound is nasalized.
English features only three nasalized sounds: /n/, /m/, and /ŋ/. Vowels in English are never nasal, however, many other languages do feature nasalized vowels. Knowing this diacritic is helpful in learning the difference.
Length [ː]
Vowel length can change the meaning of words in English. The diacritic [ː] shows that a vowel is long, while the absence of this mark indicates a short vowel.
The difference between the short vowel /ɪ/ in "bit" and the long vowel /iː/ in "beat" is indicated by the length diacritic [ː], for instance. "Beat" might be transcribed as [biːt].
Voiceless [ ̥]
The voiceless diacritic [ ̥] indicates that a typically voiced sound is produced without the vocal cords vibrating, which can happen in certain phonetic environments.
In the word "please," the /l/ sound is often devoiced due to the influence of the voiceless /p/. This can be shown with the diacritic [ ̥], so "please" might be transcribed as [pl̥iːz].
Stress [ˈ] and [ˌ]
Stress diacritics [ˈ] and [ˌ] indicate primary and secondary stress, respectively, which are important in English for distinguishing between words with similar spelling but different meanings.
In the word "record," for instance, the stress placement changes the word's meaning (noun vs. verb). Primary stress is marked with [ˈ] before the stressed syllable, so "record" (noun) might be transcribed as [ˈrɛkɔːd], while "record" (verb) could be [rɪˈkɔːd].
