The vowel in "go": American /oʊ/ vs British /əʊ/

Americans start the vowel in “go” with rounded lips, /oʊ/; standard British English starts it with relaxed lips and a central “uh” sound, /əʊ/. Both are glides that end near “oo”. Only the starting point changes, and it changes in hundreds of common words: “no”, “home”, “phone”, “road”, “know”, “most”.

All audio on this page is an AI voice (neural text-to-speech), one American and one British.

Where does the vowel in “go” start?

Linguists call this the GOAT vowel. It is a diphthong: the tongue and lips move during the sound.

  • American English: start with rounded lips and the tongue at the back, as in a pure “o”, then glide up toward /ʊ/.
  • British English (Received Pronunciation and modern southern British English): start in the middle of the mouth, with lips not yet rounded, as in the “uh” of “about”, then glide toward /ʊ/.

Listen to the first half of each vowel. The American voice sounds rounder from the start. The British voice starts flatter and rounds only at the end.

One more British detail: before a dark L, as in “goal” and “cold”, many southern British speakers start the vowel further back, closer to /ɒʊ/. American English keeps /oʊ/ there too.

Hear it in a sentence

“I know the road home.” has three GOAT words: know, road and home.

American: British:

The difference is small in each word, but it repeats three times in five words. That repetition is what makes the accent audible.

What a scorer hears

We scored both AI voices against both scoring accents. We used the same scoring engine and settings that AnyAccent uses in the app. For American English, the scorer grades each sound and also names the sound it heard.

Example result: scored as American English

How to read this:

  • The American scorer gave the British voice 100 on every single word and named its vowel /oʊ/. It treated the British glide as a normal American vowel.
  • On the full sentence, both voices scored over 95 against American English and 100 against British English.
  • Single words scored as British English were uneven: on “go”, the British scorer gave its own British voice a lower score than the American voice. Those scores do not show an accent difference, so we do not quote them.
  • So this is a difference that people hear and the scorers accept. A scorer will not push you toward one starting point or the other.

If you want a consistent accent, train this vowel by ear. Record yourself, then compare the first half of your vowel with the AI voices above.

The scores above are from single runs on AI voices. Your own scores will depend on your recording.

How to practise it

For the American /oʊ/

  1. Round your lips before you start the sound, as if you are about to whistle.
  2. Keep the tongue back.
  3. Glide only a little toward “oo”. The start is the important part.
  4. Drill the word list with a mirror: go, no, home, phone, road, know, most, slow.

For the British /əʊ/

  1. Start with relaxed, unrounded lips, as for the “uh” in “about”.
  2. Keep the tongue in the middle of the mouth.
  3. Round the lips only as you glide toward the end of the vowel.
  4. Avoid starting too far forward or too open. If “no” begins to sound like “now”, you have gone too far.

Common questions

Why do British people say “no” like “nuh-oo”?

Because the standard British vowel starts at the central “uh” sound /ə/ and then glides to /ʊ/. American English starts the same vowel with rounded lips, /oʊ/.

Is the British “o” in “go” the same as in “hot”?

No. “Hot” has one short sound, /ɒ/. “Go” has a glide, /əʊ/, that moves from “uh” toward “oo”.

Will a pronunciation app mark my “go” wrong if I mix the accents?

In our test, the American scorer gave both voices 100 on every word, and the British scorer gave both 100 on the full sentence. Mixing is still worth avoiding, because a listener hears the switch even when a scorer does not.

Practise with a scorer

AnyAccent lets you pick the accent you practise against. For American English, you get sound-level diagnosis: the app names the sound you missed. For British English, you get word and sentence scores.
