Vietnamese is a beautifully unique language, rich with culture and history. With six distinct tonal variations and words that tend to be concise, primarily consisting of one or two syllables, Vietnamese is a fascinating language. However, these same features can pose certain challenges when it comes to learning English pronunciation for Vietnamese speakers.


In this comprehensive guide, we'll explore the specific pronunciation problems that Vietnamese speakers encounter when learning English and offer valuable tips and practice exercises to help improve English pronunciation for native Vietnamese speakers. Mastering English pronunciation can be a rewarding journey, and we're here to help you bridge the gap between these two linguistic worlds. 


Whether you're new to English or have been studying for a while, our guide will provide the guidance you need to sound more fluent and natural in your English communication. So let's dive into the world of English pronunciation for Vietnamese speakers and discover how to overcome those pesky pronunciation problems!

Differences in English and Vietnamese Consonants

Vietnamese has unique tones and consonants that are not found in English, leading to distinct pronunciation challenges for native speakers learning the American accent. Let's review some of the most common difficulties with English consonants.

"TH" Sounds

Pronouncing the "TH" sounds can be a challenging aspect of English pronunciation for Vietnamese speakers. There are two distinct "TH" sounds in English: the voiceless "th" (θ) and the voiced "TH" (ð).


The voiceless "th" is created by placing the tip of the tongue between the upper and lower front teeth, allowing air to pass through without vocal cord vibration. Words like "think" and "both" feature this sound. 



On the other hand, the voiced "TH" is produced the same way but with vocal cord vibration, as heard in words like "this," "brother," and "weather." To master these sounds it's essential to maintain the correct tongue positioning, keeping the tongue lightly touching the upper front teeth with a small gap for air. 



Practice activities include repeating words with "TH" sounds, tongue twisters, minimal pairs to distinguish between the two "TH" sounds, and listening to native speakers. Utilizing a mirror to observe your mouth and tongue positioning can also aid your progress. Patience and consistent practice are key to overcoming the challenge of "TH" pronunciation and sounding more fluent in English.

“SH” Sound

For Vietnamese speakers, the "SH" sound is a crucial element in English pronunciation. While some central and southern Vietnamese dialects incorporate a similar sound, mastering the nuances of the English "SH" sound is essential.


To pronounce it correctly, slightly part your lips, position your tongue near the gum ridge just behind your upper front teeth, and release a continuous flow of air without vocal cord vibration. You'll find the "SH" sound in words like "she," "shoe," and "sure."



Effective practice activities include repeating words with the "SH" sound, using it in phrases and sentences, distinguishing it from similar sounds like "S," challenging yourself with tongue twisters, and comparing the pronunciation to your native dialect if it already includes a similar sound. Consistent practice and attention to detail will help you confidently use the "SH" sound in English, whether it's a familiar element from your dialect or a new addition to your linguistic toolkit.

“CH” Sounds

The "CH " sound can be a source of difficulty for Vietnamese speakers learning English. To produce this sound place the tip of your tongue just behind your upper front teeth, create a slight constriction, and release a burst of air. This sound is voiceless (so you won't feel a buzz in your throat when you make it) and can be found in words like "cheese," "church," and "chat." 



To improve your "CH" pronunciation, start with repeating words like "chocolate" and "chair," then progress to using "CH" in phrases and sentences.  


As you can see in the following video of President Hồ Chí Minh, distinguishing between “SH” and “CH” sounds can be difficult for Vietnamese speakers. To improve this distinction, practice using minimal pairs such as “share” and “chair.”



With time and consistent practice, you'll enhance your English pronunciation, confidently using the "CH" sound in everyday conversations.

“J” Sound

The "J" sound in English poses an interesting challenge for Vietnamese speakers, despite some central and southern Vietnamese dialects featuring a similar sound. This sound involves bringing the middle part of your tongue close to the roof of the mouth with vocal chord vibration. You'll encounter the "J" sound in words like "jump," "just," and "jury."




Consistent practice and a keen ear for distinctions will empower you to confidently use the "J" sound in English, whether it's already familiar from your dialect or a new addition to your linguistic repertoire. By bridging this gap, you'll enhance your English pronunciation and communication skills.

“Z” Sound

Although the "Z" sound does exist in some northern Vietnamese dialects, it can present a fascinating challenge for Vietnamese speakers learning English. This sound involves bringing the tip of your tongue near the bumpy gum ridge behind your upper front teeth, without making contact and while allowing the vocal cords to vibrate. You'll encounter the "Z" sound in words like "zebra," "zero," and "amazing."



To refine your pronunciation of the "Z" sound start with word repetition. With consistent practice and a discerning ear for distinctions, you'll confidently incorporate the "Z" sound into your English pronunciation.

English Vowel Challenges for Vietnamese Speakers

Vietnamese speakers often face challenges with English vowels due to differences in vowel systems and the absence of certain vowel distinctions in Vietnamese. Adapting to the nuances of English vowel sounds may pose difficulties for Vietnamese learners. We'll review some of the most common challenges below.

"IH" Sound

The English "IH" or /ɪ/ sound, as heard in words like "ship," poses a challenge for Vietnamese speakers due to its shorter and tenser nature compared to similar Vietnamese vowels. Common mistakes include misjudging the duration and tense quality. To overcome this, position your tongue close to the upper front teeth, keeping it relaxed yet tense.



To improve this common pronunciation mistake, engage in minimal pair exercises, contrasting words like "ship" and "sheep." Utilize listening exercises with native speakers to grasp the nuances of vowel duration and quality.

"EE" Sound

Speaking of vowel duration, the extended duration of the English "EE" or /iː/ sound in words like "sleep" can be challenging for Vietnamese speakers. Mispronunciations often involve pronouncing it too short (often as the result of an overcorrection of the previous pronunciation mistake). Elevate your tongue close to the upper front teeth, allowing for a longer and more relaxed duration to overcome this hurdle.



Practice by focusing on words containing "EE" in minimal pair exercises, like "slip" and "sleep" or "twit" and "tweet." Record and compare your pronunciation with native speakers to refine your understanding of vowel duration.

"AA" Sound

The absence of a direct equivalent in Vietnamese makes the English "AA" or /æ/ sound, found in words like "cat," challenging for learners. Ensure your tongue is lower and more centralized in the mouth to accurately distinguish this vowel.



In order to improve your pronunciation as a native Vietnamese speaker of English, engage in partner pronunciation practice to receive feedback on the accuracy of "AA."

Common English Pronunciation Errors Made by Vietnamese Speakers

Vietnamese speakers commonly encounter pronunciation challenges in English with middle syllable pronunciation, where nuances in vowel and consonant sounds can be tricky to grasp. Additionally, placing stress correctly and reconciling disparities between English spelling and pronunciation pose notable hurdles for Vietnamese learners. We'll explore more below.

Middle Syllables

Vietnamese English learners often grapple with pronouncing the middle sounds of longer English words that contain more than two syllables. This challenge arises from the dominance of two-syllable words in the Vietnamese language, comprising about 80% of its vocabulary. As a result, mastering the intricacies of middle syllables in longer English words presents a formidable hurdle for learners.


To overcome this challenge, there are several practical exercises. Begin by breaking complex words into syllables and practicing each part individually. Pay attention to words with diphthongs, consonant clusters, and silent letters in the middle syllables (for example “vacation,” “Antarctica,” and “Wednesday” respectively). Check out this video on syllable rhythm for extra guidance.


Moreover, listening to native English speakers and mimicking their pronunciation will help learners become more proficient in correctly pronouncing the middle sounds of English words. By consistently practicing these exercises, Vietnamese learners can develop the skills needed to handle the complexities of middle syllables, enhancing their overall English pronunciation and fluency.

Stress Placement

Vietnamese speakers often grapple with English word stress, where multisyllabic words have specific syllables emphasized for meaning. In Vietnamese, syllables receive equal stress, making it challenging for learners to adopt the varying stress patterns and intonation in English. Review this video to practice your English stress placement.


Recognizing the difference between classes of words (such as nouns, verbs, etc.) and their role in a sentence can also refine word stress skills. Engaging in word stress drills and absorbing as much English language media as possible is pivotal for accurate pronunciation, enhancing overall English communication. 

Spelling and Pronunciation

Vietnamese learners of English often encounter pronunciation errors due to the influence of similar letters and letter combinations in both languages. For instance, the English "EY" or /ei/ sound may be mistakenly pronounced as "ê" or "ây" in Vietnamese, leading to words like "pay" sounding like "pê." 


To address this issue, several effective activities can be employed. Watching English-language movies with subtitles and reading along with song lyrics allows learners to associate written words with their correct English pronunciation, bridging the gap between spelling and speech.


Additionally, becoming familiar with the International Phonetic Alphabet (IPA) for transcription and utilizing online pronunciation guides can help clarify and refine pronunciation, while practicing with native speakers offers valuable feedback and correction. By embracing these activities, Vietnamese learners can overcome pronunciation challenges and enhance their English communication skills.
