Have you ever wondered why, despite learning so much vocabulary and grammar, you still don’t feel truly confident when speaking English? Or why native speakers sometimes don’t understand you, even when you’re trying your best? The root cause often lies in your English pronunciation—and the International Phonetic Alphabet (IPA) is the “compass” you need to solve this problem.

Unlike Vietnamese, where you can often “read what you see,” English has a significant disconnect between spelling and pronunciation. That is why mastering the English IPA chart is not just a foundational skill; it is the key to transforming your communication, listening comprehension, and confidence in any situation.

1. What is the IPA chart?

The International Phonetic Alphabet (IPA) is a system of phonetic symbols developed by linguists worldwide to accurately represent every sound in spoken language. Simply put, the IPA is the “native language” of sounds, allowing you to know exactly how to pronounce a word even if you have never heard it before.

The English IPA chart consists of 44 basic sounds, divided into 20 vowel sounds and 24 consonant sounds. When you look up a word in a dictionary, you will always see the IPA transcription in slashes (/ /) or brackets ([ ]) next to it.

Why is learning the English IPA chart so important?

Read any word correctly, even if you’ve never heard it: With IPA, you don’t have to guess or rely on repetitive listening. Just by looking at the transcription, you can accurately pronounce any word, including new ones.

Example: The word “read” is spelled the same, but in the present tense, it is /riːd/ (long vowel), while in the past tense, it is /red/ (short vowel). IPA helps you distinguish these clearly. Or the word desert, which can be a noun /ˈdez.ət/ (a dry region) or a verb /dɪˈzɜːrt/ (to abandon), differing entirely in stress and vowel sounds.

Significantly improve listening skills: When you know how a sound is produced and can pronounce it correctly, your brain will find it much easier to recognize that sound when listening to native speakers. This helps you understand faster and more accurately, avoiding the “muffled” or unclear listening experience.
Break down communication barriers and boost confidence: Clear pronunciation ensures your message is conveyed accurately and coherently, preventing misunderstandings. When you no longer worry about mispronouncing words, you will feel much more confident in conversations, opening doors to natural and effective communication.
A solid foundation for all skills: Pronunciation is the root of speaking and listening. Mastering IPA is a crucial stepping stone to developing all your other English skills comprehensively.

2. Structure of the English IPA chart: A system of 44 standard sounds

To master the English IPA chart, we will dive into each group of sounds, how to produce them, and common mistakes made by Vietnamese learners.

2.1. Vowels – 20 sounds

Monophthongs and diphthongs in the IPA chart

Vowels are sounds produced when the airflow from the lungs passes out without being obstructed.

a. Monophthongs – 12 sounds

These are basic sounds produced with a fixed position of the tongue and lips.

/ɪ/ (Short i):

How to pronounce: Similar to the Vietnamese “i” but shorter and sharper. The lips are slightly spread, and the tongue is lowered and relaxed.
Example: sit /sɪt/, pin /pɪn/, fish /fɪʃ/
Common mistakes & fixes: Often lengthened into /iː/. You need to make the sound very short and crisp.

/iː/ (Long ee):

How to pronounce: A long “i” sound, produced deep in the mouth without blowing air out. The lips are spread wide as if smiling, and the tongue is raised.
Example: see /siː/, tree /triː/, sleep /sliːp/
Common mistakes & fixes: Often read as a standard Vietnamese “i” without length. Keep your mouth “tense” and hold the sound.

/e/ (Short e):

How to pronounce: Similar to the Vietnamese “e” but shorter. The lips are spread wider than for /ɪ/, and the tongue is lower than for /ɪ/.
Example: pen /pen/, bed /bed/, friend /frend/
Common mistakes & fixes: Easily confused with /æ/ or /ɪ/. Keep the mouth opening moderate and the sound short.

/æ/ (Flat a):

How to pronounce: A flat “a” sound, a mix between “a” and “e,” feeling as if the sound is compressed. The mouth is wide open, the lower lip is lowered, and the tongue is very low.
Example: cat /kæt/, man /mæn/, bad /bæd/
Common mistakes & fixes: Often read as a standard Vietnamese “a.” You need to open your mouth wide, flatten it, and lower your jaw significantly.

/ʌ/ (Short u):

How to pronounce: A sound between the Vietnamese “ă” and “ơ,” closer to “ă.” It must be produced with a burst of air. The mouth is narrowed, and the tongue is slightly raised.
Example: cup /kʌp/, love /lʌv/, sun /sʌn/
Common mistakes & fixes: Often read as “a” or “ơ.” You need to push the air out strongly, shortly, and crisply from the throat.

/ɒ/ (Short o):

How to pronounce: Similar to the Vietnamese “o” but shorter. The lips are slightly rounded, and the tongue is lowered.
Example: hot /hɒt/, dog /dɒɡ/, box /bɒks/
Common mistakes & fixes: Often lengthened into “o.” Keep it short and maintain moderate lip rounding.

/uː/ (Long oo):

How to pronounce: A sound produced in the mouth without blowing air out, extending the short “u.” The lips are rounded, and the tongue is raised.
Example: moon /muːn/, food /fuːd/, school /skuːl/
Common mistakes & fixes: Often read as a standard Vietnamese “u” without length or rounding. Keep the lips rounded and hold the sound.

/ʊ/ (Short oo):

How to pronounce: Quite similar to the Vietnamese “ư.” When pronouncing, do not use the lips; push a very short burst of air from the throat. The lips are slightly rounded, and the tongue is lowered.
Example: book /bʊk/, look /lʊk/, good /ɡʊd/
Common mistakes & fixes: Often confused with /uː/. Keep the sound short and relax the lips and tongue.

/ɑː/ (Long a):

How to pronounce: A long “a” sound, produced in the mouth. The lips are wide open, and the tongue is lowered.
Example: car /kɑːr/, start /stɑːrt/, father /ˈfɑːðər/
Common mistakes & fixes: Often read as a standard Vietnamese “a” without depth or length. Open your mouth comfortably, relax your tongue, and hold the sound.

/ɔː/ (Long o):

How to pronounce: Like the Vietnamese “o” but with the tongue curled (if followed by R), produced deep in the mouth. Round the lips and curl the tongue to touch the roof of the mouth when finishing the sound.
Example: talk /tɔːk/, law /lɔː/, door /dɔːr/
Common mistakes & fixes: Often read as a standard “o.” Round your lips and feel the sound deep in your throat, then extend it.

/ɜː/ (Long er):

How to pronounce: A long “ơ” sound. Pronounce “ơ” while curling the tongue (in American English), produced in the mouth. The lips are slightly spread, the tongue is curled, and it touches the roof of the mouth when finishing the sound.
Example: bird /bɜːrd/, word /wɜːrd/, first /fɜːrst/
Common mistakes & fixes: Often read as a standard “ơ.” Remember to curl the tongue inward (r-colored vowel) and extend the sound.

/ə/ (Schwa):

How to pronounce: The schwa (ə) is a short, unstressed sound, often found in unstressed syllables. The lips and tongue are in a neutral position; no muscle tension is required.
Example: about /əˈbaʊt/, banana /bəˈnænə/, doctor /ˈdɒktər/
Common mistakes & fixes: Often stressed or pronounced too clearly. Keep it extremely light, relaxed, and almost “swallowed.”

b. Diphthongs – 8 sounds

A combination of two monophthongs, where the first sound is stronger and glides smoothly into the second.

/eɪ/ (ei):

How to pronounce: Glide smoothly from /e/ to /ɪ/. The lips gradually spread, and the tongue moves upward.
Example: face /feɪs/, day /deɪ/, make /meɪk/
Common mistakes & fixes: Often read as a standard Vietnamese “ây.” Feel the slight glide from “e” to “i.”

/aɪ/ (ai):

How to pronounce: Glide from /ɑː/ to /ɪ/. The lips gradually spread, and the tongue rises and pushes slightly forward.
Example: my /maɪ/, light /laɪt/, time /taɪm/
Common mistakes & fixes: Often read too stiffly. Glide gently without interruption.

/ɔɪ/ (oi):

How to pronounce: Glide from /ɔː/ to /ɪ/. The lips gradually spread, and the tongue rises and pushes forward.
Example: boy /bɔɪ/, choice /tʃɔɪs/, noise /nɔɪz/
Common mistakes & fixes: Read too stiffly or lacking the glide. Pay attention to the initial lip rounding and tongue movement.

/əʊ/ (ou):

How to pronounce: Glide from /ə/ to /ʊ/. The lips move from slightly open to slightly rounded, and the tongue moves backward.
Example: go /ɡəʊ/, snow /snəʊ/, boat /bəʊt/
Common mistakes & fixes: Often read as a single “ô.” Feel the movement of the lips from open to slightly rounded.

/aʊ/ (au):

How to pronounce: Glide from /ɑː/ to /ʊ/. The lips gradually round, and the tongue pulls back slightly.
Example: cow /kaʊ/, house /haʊs/, mouth /maʊθ/
Common mistakes & fixes: Often read as a standard Vietnamese “ao.” Pay attention to the lip rounding at the end and the glide.

/ɪə/ (ea):

How to pronounce: Glide from /ɪ/ to /ə/. The lips open gradually but not too wide, and the tongue pushes forward.
Example: near /nɪər/, here /hɪər/, idea /aɪˈdɪə/
Common mistakes & fixes: Often read as a stiff “ia.” Glide gently and keep it relaxed.

/eə/ (ea):

How to pronounce: Glide from /e/ to /ə/. The lips narrow slightly, and the tongue pulls back.
Example: hair /heər/, care /keər/, square /skweər/
Common mistakes & fixes: Often read as a single “e” or lacking the glide.

/ʊə/ (oo):

How to pronounce: Glide from /ʊ/ to /ə/. The lips are rounded and slightly protruded, the tongue moves toward the roof of the mouth, then the mouth opens slightly as the tongue moves back to the center.
Example: tour /tʊər/, cure /kjʊər/, sure /ʃʊər/
Common mistakes & fixes: This sound is less common and often read as a stiff “ua.” Feel the gentle glide.

2.2. Consonants – 24 sounds

Consonants are sounds produced when the airflow from the lungs is obstructed by parts of the mouth (lips, teeth, tongue, palate).

/p/ (Voiceless Plosive):

How to pronounce: Close both lips to block the airflow, then release it strongly. Do not vibrate the vocal cords.
Example: pen /pen/, stop /stɒp/, apple /ˈæpəl/

Common mistakes & fixes: Often lacks aspiration. Place your hand in front of your mouth; if you feel a strong puff of air, you’re doing it right.

/b/ (Voiced Plosive):

How to pronounce: Same as /p/ but with vocal cord vibration. Close lips, release, and feel the vibration in your throat.
Example: back /bæk/, job /dʒɒb/, baby /ˈbeɪbi/

Common mistakes & fixes: Often read as /p/ if you don’t vibrate your vocal cords.

/t/ (Voiceless Plosive):

How to pronounce: Place the tip of the tongue behind the upper front teeth to block the airflow, then release strongly. Do not vibrate the vocal cords.
Example: time /taɪm/, get /ɡet/, water /ˈwɔːtər/
Common mistakes & fixes: Often lacks aspiration or the aspiration is too weak.

/d/ (Voiced Plosive):

How to pronounce: Same as /t/ but with vocal cord vibration. Place tongue tip behind upper teeth, release, and feel the vibration.

Common mistakes & fixes: Easily confused with /t/ if you don’t vibrate your vocal cords.

/k/ (Voiceless Plosive):

How to pronounce: Raise the back of the tongue to touch the soft palate, block the airflow, then lower the tongue and release strongly. Do not vibrate the vocal cords.
Example: cat /kæt/, back /bæk/, kick /kɪk/
Common mistakes & fixes: Lacks aspiration.

/g/ (Voiced Plosive):

How to pronounce: Same as /k/ but with vocal cord vibration. Raise the back of the tongue, release, and feel the vibration.
Example: go /ɡəʊ/, dog /dɒɡ/, game /ɡeɪm/
Common mistakes & fixes: Easily confused with /k/.

/tʃ/ (Voiceless Affricate):
