Fricative sounds—those tricky little consonants that can be the difference between “thank” and “tank”—are essential to mastering clear and confident English pronunciation .
In English, fricatives are a small group of consonants that are characterized by the friction created when air passes through a narrow gap in the mouth. While they may seem subtle, mispronouncing fricative consonants can lead to confusion or make your accent sound less polished.
For non-native speakers, perfecting these sounds can be the key to eliminating some of the last barriers to truly fluent English pronunciation.
This guide will help you understand and master the nine fricative consonant sounds in English, so you can get it right every time.
What Are Fricatives? Fricatives are consonants produced by forcing air through a narrow channel in the vocal tract, creating a slight friction sound. Unlike plosives, which involve a complete closure and release of air (like /p/ or /t/ ), fricative consonants allow air to pass continuously through the mouth or throat.
When you pronounce a fricative consonant, you position your tongue, teeth, and lips in such a way that the airflow is constricted but not entirely blocked. The friction created by this airflow produces the distinctive fricative sound.
For example, to produce the /f/ sound, you place your upper teeth against your lower lip and blow air through the gap, creating the characteristic /f/ sound, like at the beginning of the word “food.”. Now compare this to a sound like /p/, where you block and release air for a popping sound—this difference in airflow is what makes a fricative unique.

Why Fricatives Matter in English Pronunciation Fricatives are everywhere in English, and nailing their pronunciation is key. These sounds pop up in everyday words like "this," "think," and "very," and mispronouncing them can quickly lead to confusion.
For many non-native speakers, fricatives are a challenge because they either don’t exist, or are pronounced differently, in other languages. Get them right, and your speech will be clearer and more natural to native ears.
For example, the English /θ/ sound in “think” doesn’t exist in languages like Spanish or Russian , so speakers of those languages often substitute it with a /t/, /d/, or /s/ sound, making “think” sound like “tink” or “sink.”
Learning the subtle differences between these sounds is key to speaking English clearly and confidently, minimizing misunderstandings and streamlining communication.
The 9 Fricative Sounds in English Without further ado, let’s break down the nine fricative sounds in English. These are grouped into voiceless, voiced , and glottal fricatives, each requiring a unique way of manipulating airflow through your mouth and throat.
Voiceless fricatives are consonant sounds produced by forcing air through a narrow opening without vibrating the vocal cords, creating a soft, airy friction.
1. /f/ as in "fun"
The /f/ sound is an unvoiced fricative, which means there’s no vibration in your vocal cords when producing it.
To create this sound, place your upper teeth gently on your lower lip and blow air out, creating a soft, continuous friction. It’s similar to the feeling of letting air escape from a small opening.
VIDEO
You’ll encounter this sound in many common words such as "fun,""find," and even at the end of words like "laugh."
Interestingly, the /f/ sound can also be represented by the letters "ph" in words like "phone."
It’s one of the more straightforward fricatives in English pronunciation because it has a clear, sharp sound, making it easy to recognize in conversation.
2. /θ/ as in "think"
The /θ/ sound , often referred to as the “soft th,” is one of the trickier fricatives for non-native speakers, as it doesn’t appear in many other languages.
To produce /θ/, place the tip of your tongue lightly between your upper and lower teeth—just barely peeking out—and blow air through the gap. There should be a light, airy hiss as you pronounce it, like in the words "think," "thank," or "both."
VIDEO
This sound is represented by the "th" spelling in English, and it often trips up speakers of languages like Spanish or French , where a similar sound doesn’t exist.
Practicing this subtle tongue placement is key to making sure you don’t accidentally turn "think" into "sink." Consider using minimal pairs exercises to really dive into the details and fine-tune your English pronunciation!
3. /s/ as in "sun"
The /s/ sound is another voiceless fricative, but this time, the friction is created by placing your tongue near the roof of your mouth, just behind your upper teeth. You then blow air out, producing a sharp, hissing sound.
VIDEO
It’s one of the most common sounds in English and can be found in words like "sun," "kiss," and "cease."
This fricative is typically spelled with an "s," but it can also be represented by a "c" as in "cease" or "city." It’s important to maintain the airflow while keeping your vocal cords still—no vibration here—making it distinct from its voiced counterpart , /z/.
4. /ʃ/ as in "ship"
The /ʃ/ sound, often referred to as the “sh” sound, is a voiceless fricative that’s slightly more complex than /s/.
To produce it, push your tongue back slightly from the /s/ position and blow air out. The sound is softer and more drawn out than /s/, creating the familiar sound found in words like "ship," "sure," or "push."
VIDEO
This sound is spelled as "sh" in many words, but it also appears in more unexpected spellings like "ti" in "nation."
While /s/ is crisp and sharp, /ʃ/ has a more elongated and mellow quality, so the shift in tongue placement is crucial for mastering it.
Voiced fricatives are similar to their voiceless counterparts but with one major difference: your vocal cords vibrate while producing the sound. This slight vibration adds richness and depth to the fricative.
5. /v/ as in "van"
The /v/ sound is the voiced version of /f/. To produce it, place your upper teeth on your lower lip, just as you would with /f/, but this time, vibrate your vocal cords as you blow air out.
The result is a buzzing sound, which you can feel if you place your hand on your throat. Words like "van," "vivid," and "save" use this sound.
VIDEO
In terms of spelling, /v/ is typically represented by the letter "v," making it a consistent sound to identify and replicate.
The key to distinguishing it from /f/ is the vibration in your throat—without it, the sound becomes voiceless.
6. /ð/ as in "this"
The /ð/ sound , often called the “hard th,” is the voiced counterpart of /θ/. To create /ð/, place the tip of your tongue between your teeth just like you do for /θ/, but this time, vibrate your vocal cords as you blow air out.
It’s a slightly stronger sound, as in the words "this," "father," or "with."
VIDEO
The spelling for this sound is also "th," but it’s voiced, which makes it stand out from the softer, voiceless /θ/. Non-native speakers often struggle to differentiate between these two sounds, but focusing on whether or not your vocal cords are engaged can help fine-tune your pronunciation.
7. /z/ as in "zoo"
The /z/ sound is the voiced version of /s/. To pronounce it, position your tongue in the same place as for /s/—close to the roof of your mouth, behind your teeth—and blow air out while vibrating your vocal cords.
It’s the buzzing sound you hear in words like "zoo," "buzz," and "easy."
VIDEO
While it’s typically spelled with a "z," you’ll also find it represented by "s," as in "easy" or "please."
The difference between /s/ and /z/ is subtle, but mastering this shift from voiceless to voiced can make your speech sound more natural and fluent.
8. /ʒ/ as in "measure"
The /ʒ/ sound is the voiced version of /ʃ/. It’s a bit more unusual in English, found in words like "measure," "pleasure," and "beige."
To produce /ʒ/, push your tongue back slightly from the /s/ position, just as you would with /ʃ/, and blow air out while vibrating your vocal cords.
VIDEO
Although it’s spelled with "s" in "measure" and "g" in "beige," this sound doesn’t appear in as many common words as other fricatives. However, mastering it adds sophistication to your pronunciation, especially when dealing with words borrowed from French.
9. /h/ as in "hat"
The /h/ sound is a voiceless fricative produced at the glottis, which is located in the throat.
To make this sound, you simply push air out through your open vocal cords without vibrating them. It’s one of the easiest fricatives to produce, as it doesn’t require precise tongue placement or friction in the mouth.
VIDEO
You can hear it clearly in words like "hat," "happy," and "ahead."
The spelling is almost always "h," making it one of the more predictable fricatives in English. However, it’s important to remember that this sound is very light, almost a gentle puff of air, and doesn’t carry much weight in pronunciation.
How to Master Fricatives: Tips and Tricks Mastering fricatives takes consistent practice, but with the right techniques, you can develop accurate and confident pronunciation.
1. Recognizing Voiced vs. Voiceless Fricatives
One of the first steps to mastering fricatives is understanding the distinction between voiced and voiceless sounds .
Voiced fricatives, like /v/ or /z/, require you to engage your vocal cords, while voiceless fricatives, like /f/ or /s/, rely purely on airflow.
To easily differentiate between them, place your hand on your throat while saying each sound. If you feel a vibration, it’s a voiced fricative; if not, it’s voiceless. This technique is especially useful for distinguishing tricky pairs like /f/ and /v/ or /θ/ and /ð/.
2. Minimal Pairs Practice
Practicing minimal pairs —words that differ by only one sound—can sharpen your ability to distinguish between fricatives.
Focus on pairs like /f/ vs. /v/ or /s/ vs. /z/. Start by saying words like “fan” and “van” or “seal” and “zeal,” paying attention to the subtle differences in how your mouth and vocal cords behave.
This exercise trains your ear and speech muscles to accurately produce each fricative.
3. Study the IPA Chart
Studying the International Phonetic Alphabet (IPA) can be a helpful way to reinforce your understanding of fricatives. The IPA gives you a visual guide to each sound, so you can better identify the fricatives in words.
By becoming familiar with the IPA symbols for each fricative, you’ll find it easier to map the sounds to their written forms, helping you both recognize and produce these sounds with greater ease.
4. Consistent Practice and Feedback
Of course, consistency is key when it comes to mastering fricatives. Regular practice with real-time feedback allows you to catch mistakes early and make adjustments.
