Your Accent Isn’t a Speech Error: R, TH, T and Vowels in US, UK, Australian and Indian English (Chart)

✓ Reviewed against ASHA Practice Portal: Accent Modification, JIPA Illustrations: American, British (RP) and Australian English, Wells 1982, Accents of EnglishEvidence level BLast reviewed October 30, 2026Published October 30, 2026

American, British, Australian and Indian English differ by rule: whether R is said after a vowel, how TH, T and W/V are made, and many vowels. None of those differences is a speech error, and everyone has an accent. A speech-sound difference is one that differs from your own English, like an S that sounds like TH.

The short answer: every English has rules, and following them is correct

Accents are not a communication disorder, and everyone has one. ASHA’s position on dialects has said the same for decades: a variety of English is a rule-governed system, not a faulty version of another one.^1,2

The chart below shows where four major Englishes differ, with the sources that describe each. Read it as “what’s normal in this English”, not “what’s right”.

The chart: how four Englishes differ

Typical features of four varieties of English. Every cell is a normal feature of that English, not an error; individual speakers and regions vary.
Feature	Example words	US English (General American)	UK English (standard southern British)	Australian English	Indian English
R after a vowel	car, four, bird	said (an R or R-coloured vowel)	not said, unless a vowel follows	not said, unless a vowel follows	varies by speaker and region
R before a vowel	red, carrot, three	said	said	said	said; its sound varies with the speaker’s first language
TH	think, this	TH	TH (F and V in some accents, such as London)	TH	often T- and D-like sounds made against the teeth
T between vowels	water, butter	often a quick D-like tap	T, or a catch in the throat in many accents	often a quick D-like tap	often made with the tongue tip curled back
W and V	wine, vine	two different sounds	two different sounds	two different sounds	often one sound between W and V
Vowels in “face” and “goat”	day, go	gliding vowels	gliding vowels	gliding vowels, with their own quality	often single, steady vowels
Vowel in “bath”	bath, dance	as in “cat”	as in “father”	varies by word	varies

Typical features of four varieties of English. Every cell is a normal feature of that English, not an error; individual speakers and regions vary.^3,4,5,7,6

Two points the chart makes clear. First, the biggest single divide is R after a vowel: American English says it, while standard British and Australian English don’t. Second, Indian English isn’t one fixed accent: research on speakers with different first languages found both shared Indian English patterns and patterns carried over from each speaker’s first language.^3,4,5,6

What is a speech-sound difference in every English

A speech-sound difference is one that sounds different from your own community’s English, in your own words. These show up whatever the accent:⁸

Differences that aren’t explained by accent.
What you hear	Why it isn’t accent
S that sounds like TH (“thun” for “sun”)	no major English turns S into TH by rule; it’s a common sign of a frontal lisp
A wet or slushy S or SH	air escaping at the sides of the tongue isn’t an accent feature
W for R (“wed”) past childhood	in an English that says that R, W for R isn’t a regular rule
F for TH, where your English uses TH	accent in London English, but a difference in an English that says TH

Differences that aren’t explained by accent.^8,7

Age matters too: some of these are normal in young children while the sounds are still developing. Voiceless TH is the last English consonant children master, at around 6 to 7 years.⁹

Not accent reduction

Changing an accent is a choice some people make, for their own reasons. ASHA calls it accent modification, an elective service that “is not remediation of a disorder”. SpeechStep isn’t accent reduction: it practises speech sounds within your own English, and leaves your accent alone.¹

How SpeechStep listens to your English

It listens with one of four English profiles: American, British, Indian or Australian. It suggests one from where you are, and you can change it on the practice screen.
In the British and Australian profiles, an R after a vowel isn’t asked for, so “car” without an R isn’t counted as an error.
TH and L have no AI judgement in any profile, so a TH said as T, D or F is never marked as an error.
On S and Z, the AI catches swapped sounds, such as a TH where the S should be, in every profile.
When it isn’t confident about a recording, it asks you to try again rather than give a verdict.

We keep widening what each profile accounts for, and this page lists what it covers today.

Frequently asked questions

Is my accent wrong?＋

No. ASHA is clear that accents, regional, foreign or nonnative, are not a communication disorder, and that everyone has an accent. American, British, Australian and Indian English each have their own rules for sounds, and following your English’s rules is correct English.

Do British people pronounce the R in “car”?＋

Not in standard British English: R is said only before a vowel, so “car” and “four” end in a vowel, while “red” and “carrot” have an R. Australian English works the same way. American English says R after vowels too. Some British accents, such as in Scotland, do say it.

Is Indian English “correct” English?＋

Yes. Indian English is a variety of English with its own sound patterns, studied in its own right; research also shows those patterns vary with a speaker’s first language. Its features are accent, not error.

Should I change my accent?＋

Only if you want to. Changing an accent is an elective service some speech-language pathologists offer, called accent modification, and ASHA is explicit that it isn’t treatment of a disorder. SpeechStep isn’t accent reduction: it practises speech sounds within your own English.

What counts as a speech error, then?＋

A sound that’s made differently from your own English, in your own words: for example an S that sounds like TH, a wet or slushy S, or W for R past childhood in an English that says that R. Those show up whatever the accent.

Does SpeechStep mark accent differences as errors?＋

It listens with one of four English profiles, suggested from where you are and changeable on the practice screen. Differences a profile accounts for aren’t counted as errors: the British and Australian profiles don’t ask for an R after a vowel, and TH and L have no AI judgement in any profile, so a TH said as T, D or F is never marked.
