How to Pronounce the AW Vowel [ɔ] in American English
If your word “law” sounds too much like “low,” or your word “talk” sounds flat instead of rounded, one specific vowel sound may be causing the problem.
That sound is the AW vowel, written in IPA as [ɔ].
You hear this vowel in words like:
- law
- saw
- talk
- walk
- coffee
- boss
- call
- bought
- thought
- awful
- automatic
For many non-native English speakers, this sound is tricky because it sits between two other sounds:
- AH [ɑ], as in father or hot
- OH /oʊ/, as in go, no, and home
The AW vowel [ɔ] is not exactly AH, and it is not OH. It is an open, rounded vowel.

What Is the AW Vowel [ɔ]?
The AW vowel [ɔ] is the rounded vowel sound in words like:
- law
- saw
- call
- talk
- walk
- bought
- thought
- coffee
In American English, this sound can vary depending on the region. Some American speakers pronounce AW [ɔ] and AH [ɑ] very similarly because of something called the cot-caught merger.
That means some speakers pronounce pairs like cot and caught the same way.
But for accent clarity, especially if you are a non-native English speaker, it is useful to learn the controlled version of AW [ɔ]:
open jaw plus rounded lips
That is the main idea.
The AW vowel is open like AH [ɑ], but the lips are rounded like OH /oʊ/.
For a broader overview of where this sound fits in English pronunciation, read our guide to the 44 sounds in English.
Why the AW Vowel Matters
The AW vowel matters because it helps you avoid replacing words like law, talk, coffee, and boss with an OH /oʊ/ sound.
This is one of the most common mistakes I hear from non-native English speakers.
For example, instead of:
law
some learners say something closer to:
low
Instead of:
talk
they say something closer to:
toke
Instead of:
coffee
they may say something closer to:
coh-fee
This can make the accent sound less natural and sometimes create confusion.
Compare:
| AW [ɔ] | OH /oʊ/ |
| law | low |
| saw | so |
| bought | boat |
| caught | coat |
| talk | toke |
These are different sounds in American English.
The AW vowel is open and rounded.
The OH vowel moves. It starts more rounded and glides forward.
If you want clearer American pronunciation, you need to avoid turning every AW word into an OH word.
How to Make the AW Vowel [ɔ]
The easiest way to understand the AW vowel is to think of it as a hybrid sound.
It combines two physical movements:
- The jaw drop from AH [ɑ]
- The lip rounding from OH /oʊ/
Start with AH:
ah
Your jaw drops down.
Now think of OH:
oh
Your lips round.
For AW [ɔ], combine those two things.
Open your jaw, but keep your lips rounded.
Try this:
aw
The mouth should feel open, but the lips should form a rounded shape.
Now say:
law
saw
talk
call
coffee
Do not say:
low
so
toke
coal
coh-fee
The AW vowel does not have the same glide as OH /oʊ/. It should stay steady.
Mouth Position for AW [ɔ]
Use this checklist:
- Drop your jaw.
- Round your lips.
- Keep the sound open.
- Do not glide into OH.
- Do not flatten the lips completely.
- Keep the vowel steady.
A helpful formula is:
AH jaw plus OH lips
That gives you AW [ɔ].
Try saying these slowly:
aw
law
saw
call
talk
bought
You should feel the jaw open and the lips round at the same time.
AW [ɔ] vs OH /oʊ/
The most important contrast for this sound is AW [ɔ] vs OH /oʊ/.
The OH sound appears in words like:
- go
- no
- home
- over
- phone
- boat
The AW sound appears in words like:
- law
- saw
- call
- talk
- thought
- bought
Compare:
| AW [ɔ] | OH /oʊ/ |
| law | low |
| saw | so |
| bought | boat |
| caught | coat |
| walk | woke |
| talk | toke |
Practice slowly:
law, low
saw, so
bought, boat
caught, coat
talk, toke
The OH sound /oʊ/ glides. Your lips move and the sound changes.
The AW sound [ɔ] is steadier. Your jaw is open and your lips stay rounded.
Try these sentences:
I studied law.
The price is low.
I bought a bag.
I was on a boat.
We need to talk.
He told a joke.
Your goal is to make law different from low, and bought different from boat.
AW [ɔ] vs AH [ɑ]
The AW vowel [ɔ] can also be confused with the AH vowel [ɑ].
The AH vowel appears in words like:
- father
- hot
- not
- stop
- problem
The AW vowel appears in words like:
- law
- saw
- thought
- caught
- coffee
- boss
The biggest difference is lip rounding.
For AH [ɑ], the lips are relaxed and unrounded.
For AW [ɔ], the lips are rounded.
Compare:
| AW [ɔ] | AH [ɑ] |
| caught | cot |
| dawn | Don |
| caller | collar |
| stalk | stock |
| bought | bot |
In some American regions, these pairs may sound the same or almost the same. That is regional variation.
However, if you are trying to build a clear American pronunciation system, it is helpful to understand the difference:
AW has rounded lips.
AH does not.
If you struggle with the AH side of this contrast, read the guide to the AH vowel [ɑ] in American English.
The Cot-Caught Merger
You may hear different American speakers pronounce AW words differently.
For example, some speakers pronounce:
cot and caught
the same way.
Other speakers pronounce them differently.
This is called the cot-caught merger.
Because of this, you do not need to panic if you hear variation in words like:
- coffee
- boss
- caught
- bought
- thought
- office
Some American speakers use a more rounded AW sound. Others use a more open AH-like sound.
For non-native speakers, the safest rule is this:
Do not replace AW with OH.
In other words, if you say coffee with an AH-like vowel, many Americans may still understand it naturally. But if you say it with a strong OH sound, it may sound much less American.
So if you make a mistake, it is usually better to move slightly toward AH [ɑ] than toward OH /oʊ/.
The main thing to avoid is:
law sounding like low
talk sounding like toke
bought sounding like boat
Common Spellings for the AW Vowel [ɔ]
The AW vowel can be spelled in several different ways. This is one reason it can feel confusing.
Here are the most common spelling patterns.
1. A Before L
The letter A often makes the AW sound before L.
Examples:
- tall
- call
- fall
- ball
- wall
- small
- always
- also
Practice:
tall
call
fall
small
Do not say these with a flat AH sound or an OH glide.
Say them with an open, rounded AW sound.
2. O Spelling
The AW vowel can also appear in some words spelled with O.
Examples:
- coffee
- boss
- office
- cost
- lost
- often
- cloth
- long
Important note: these words can vary by region. Some American speakers pronounce them closer to AH [ɑ], while others use a more rounded AW [ɔ].
For clear practice, avoid turning them into OH /oʊ/.
Say:
coffee
Not:
coh-fee
Say:
boss
Not:
bohss
Say:
office
Not:
oh-ffice
3. OUGH and AUGHT
The AW vowel appears in words with ought and aught spellings.
Examples:
- bought
- thought
- sought
- fought
- brought
- caught
- taught
- daughter
Practice:
bought
thought
caught
taught
These are very common AW words, and they are useful for pronunciation practice because the spelling looks complicated but the vowel is consistent.
4. AU Spelling
The spelling AU often gives the AW sound.
Examples:
- autumn
- automatic
- author
- August
- because
- cause
- pause
- launch
- laundry
Practice:
author
automatic
August
cause
pause
launch
Keep the lips rounded.
5. AW Spelling
The spelling AW is the most obvious one.
Examples:
- law
- saw
- raw
- draw
- awful
- awesome
- awkward
- lawn
- dawn
- yawn
- paw
Practice:
law
saw
awesome
awkward
lawn
dawn
This spelling usually tells you clearly that the AW vowel is needed.
Common Mistakes With the AW Vowel [ɔ]
Here are the mistakes I hear most often.
Mistake 1: Saying OH Instead of AW
This is the biggest mistake.
Instead of:
low
Say:
law
Instead of:
boat
Say:
bought
Instead of:
toke
Say:
talk
The AW vowel should not glide like OH /oʊ/.
Keep it steady.
Mistake 2: Not Rounding the Lips
If your lips are too flat, the sound may become closer to AH [ɑ].
That may be acceptable in some American accents, but if your goal is to practice the AW sound specifically, you need lip rounding.
Try this:
Round your lips.
Drop your jaw.
Say:
aw
Then:
law
call
thought
Mistake 3: Rounding Too Much
Some learners round the lips too much and make the sound too close to OH.
Remember: AW is open.
Your jaw should stay down.
Do not make it too narrow.
Compare:
law
low
For law, the mouth is more open.
For low, the sound is more closed and glides.
Mistake 4: Trusting the Spelling Too Much
The AW vowel can be spelled many ways:
- a, as in tall
- o, as in coffee
- ough, as in bought
- au, as in author
- aw, as in law
This means spelling alone is not always enough.
You need to learn the pronunciation pattern and practice common words.

Minimal Pair Practice
Use these pairs to train your ear and mouth.
AW [ɔ] vs OH /oʊ/
- law, low
- saw, so
- bought, boat
- caught, coat
- walk, woke
- talk, toke
Practice:
law, low
saw, so
bought, boat
caught, coat
AW [ɔ] vs AH [ɑ]
- caught, cot
- dawn, Don
- stalk, stock
- caller, collar

Remember, this contrast varies by region in American English. Focus on the physical difference:
AW: rounded lips
AH: relaxed, unrounded lips
AW [ɔ] vs AA [æ]
- call, Cal
- ball, Hal
- law, laugh
- saw, sat
This contrast is less common, but it can help if your AW vowel becomes too flat or too fronted.

Now read it again.
This time, pay special attention to:
- boss
- coffee
- office
- talked
- awesome
- author
- August
- thought
- talk
- cost
- walked
- lawn
- called
- daughter
Keep the vowel open and rounded.
Quick Self-Check
Use this checklist when you practice:
- Am I dropping my jaw?
- Are my lips rounded?
- Is the vowel steady?
- Am I avoiding the OH glide?
- Can I hear the difference between law and low?
- Can I hear the difference between bought and boat?
- Am I avoiding over-rounding?
- Am I aware that some AW words vary by American region?
The most important thing is not perfection.
The most important thing is control.
If you can choose between AH, AW, and OH intentionally, your pronunciation becomes much clearer.
FAQ About the AW Vowel [ɔ]
What is the AW vowel [ɔ] in American English?
The AW vowel [ɔ] is the rounded vowel sound in words like law, saw, call, talk, bought, thought, coffee, and boss. It is made with an open jaw and rounded lips.
Is AW the same as AH?
Not exactly. The AH vowel [ɑ], as in father or hot, is open and unrounded. The AW vowel [ɔ], as in law or talk, is open and rounded. However, some American accents pronounce these sounds very similarly because of the cot-caught merger.
Is AW the same as OH?
No. AW [ɔ] and OH /oʊ/ are different sounds. AW is steady, open, and rounded. OH is a gliding vowel, as in go, no, and home. Compare law and low, or bought and boat.
Why do some Americans pronounce “caught” and “cot” the same?
This is called the cot-caught merger. In some American accents, AW [ɔ] and AH [ɑ] are pronounced the same or almost the same. This is normal regional variation.
How do I pronounce “talk” in American English?
In talk, the letter L is silent, and the vowel is usually AW [ɔ] or an AH-like vowel depending on the speaker’s accent. Do not pronounce it like toke. Keep the vowel open and avoid the OH glide.
What are common AW words?
Common AW words include law, saw, call, talk, walk, bought, thought, caught, coffee, boss, office, author, automatic, awesome, and awkward.
Final Reminder
The AW vowel [ɔ] is one of the most important rounded vowels in American English.
It helps you pronounce words like:
- law
- saw
- call
- talk
- walk
- bought
- thought
- coffee
- boss
- office
To make it correctly, remember:
- Drop your jaw.
- Round your lips.
- Keep the vowel open.
- Do not glide into OH /oʊ/.
- Do not make law sound like low.
- Do not make bought sound like boat.
- Remember that some American speakers pronounce AW closer to AH because of regional variation.
The easiest way to think about the AW vowel is:
AH jaw plus OH lips
Once you understand that combination, the sound becomes much easier to control.
