Differences in pronunciation between American English (AmE) and British English (BrE) can be divided into:

differences in accent (i.e. phoneme inventory and realisation). See differences between General American and Received Pronunciation for the standard accents in the United States and Britain; for information about other accents see regional accents of English speakers.
differences in the pronunciation of individual words in the lexicon (i.e. phoneme distribution). In this article, transcriptions use Received Pronunciation (RP) to represent BrE and General American (GAm) and to represent AmE.

In the following discussion

superscript ^A2 after a word indicates that the BrE pronunciation of the word is a common variant in AmE.
superscript ^B2 after a word indicates that the AmE pronunciation of the word is a common variant in BrE.
superscript ^A1 after a word indicates that the pronunciation given as BrE is also the most common variant in AmE.
superscript ^B1 after a word indicates that the pronunciation given as AmE is also the most common variant in BrE.

Stress

Subscript _a or _b means that the relevant unstressed vowel is also reduced to /ə/ or /ɨ/ in AmE or BrE, respectively.

French stress

For many loanwords from French where AmE has kept the original French final-syllable stress, BrE stresses an earlier syllable. French loanwords that differs in stress only are listed below.

2nd	1st	artisanal^A1, liaison_ab^A2*^{[nb 19]},^[18] macramé_ab, Renaissance_ab,^{[nb 20]} reveille

Verbs ending in –ate

Most 2-syllable verbs ending -ate have first-syllable stress in AmE and second-syllable stress in BrE. This includes castrate, cremate^A2,^[19] dictate^A2, donate^A2, locate^A2, migrate, narrate_b^A2, placate_b, prostrate, pulsate, rotate, serrate^A2, spectate, striate,^[20] translate^A1, vacate_b*^A2,^[21] vibrate^A2. Examples where AmE and BrE match include create, debate, equate, elate, negate; and mandate and probate with first-syllable stress. Derived nouns in -ator retains the distinction, but those in -ation do not. Also, migratory^B1 ^[22] and vibratory^B1 ^[23] sometimes retain the distinction.^[1]

Most longer -ate verbs are pronounced the same in AmE and BrE, but a few have first-syllable stress in BrE and second-syllable stress in AmE: elongate_a^A2, infiltrate^A2, remonstrate_ab^A2,^[24] tergiversate_a^A1^{[nb 21]}.^[25] For some derived adjectives ending -atory stress-shifting to -a(tory)- occurs in BrE. Among these cases are celebratory_a^[26] (BrE: /ˌsɛlɨˈbreɪtəri/), compensatory_a,^[27] participatory_a,^[28] regulatory_a^B1.^[29] AmE stresses the same syllable as the corresponding -ate verb (except compensatory, where AmE stresses the second syllable^[30]). A further -atory difference is laboratory^B2: AmE /ˈlæbᵊrəˌtɔːri/ and BrE /ləˈbɒrətᵊri/.^[1]^[31]

Miscellaneous stress

There are a number of cases where same-spelled noun, verb and/or adjective have uniform stress in one dialect but distinct stress in the other (e.g. alternate, prospect): see initial-stress-derived noun.

The following table lists words not brought up in the discussion so far where the main difference between AmE and BrE is in stress. Usually it also follows a reduction of the unstressed vowel. Words marked with subscript _A or _B are exceptions to this, and thus retains a full vowel in the (relatively) unstressed syllable of AmE or BrE. A subsequent asterisk, _*, means that the full vowel is usually retained; a preceding _* means that the full vowel is sometimes retained.

Words with other points of difference are listed in a later table.

Affixes

-ary,-ery,-ory,-mony, -ative, -bury,-berry

Where the syllable preceding the suffixes -ary,-ery, -ory, –mony or -ative is unstressed, AmE pronounces the antepenultimate syllable with a full vowel sound: /ˌɛri/ for -ary and -ery, /ˌɔri/ for -ory and /ˌmoʊni/ for -mony. BrE reduces the vowel to a schwa or even elides it completely: /əri/ or /ri/, and /məni/. So military is AmE /ˈmɪləˌtɛri/ and BrE /ˈmɪlɨtəri/ or /ˈmɪlɨtri/,^[39] inventory is AmE /ˈɪnvənˌtɔri/ and BrE /ˈɪnvəntᵊri/,^[40] and testimony is AmE /ˈtɛstɨˌmoʊni/ and BrE /ˈtɛstɨməni/.^[41] (The elision is avoided in carefully enunciated speech, especially with endings -rary,-rery,-rory.)

Where the syllable preceding -ary,-ery, -ory, –mony or -ative is stressed however, AmE also usually reduces the vowel: /əri/, /məni/. Exceptions include library,^[42] primary^A2,^[43] rosemary.^[44] (Pronouncing library as /ˈlaɪˌbɛri/ rather than /ˈlaɪˌbrɛri/ is highly stigmatized in AmE, whereas in BrE, /ˈlaɪbri/ is common in rapid or casual speech.)

The suffix -berry is pronounced by similar rules, except that in BrE it may be full /ˌbɛri/ after an unstressed syllable, while in AmE it is usually full in all cases. Thus we have strawberry: BrE /ˈstrɔːbᵊri/, AmE /ˈstrɔːˌbɛri/, and whortleberry: BrE/AmE /ˈwɔːrtlˌbɛri/.

The placename component -bury (e.g. Canterbury) has a similar difference: AmE has a full vowel: /ˌbɛri/ wher BrE has a reduced or none at all: /bᵊri/.

Note that stress differences between the dialects occur with some words ending in -atory (listed above) and a few others like capillary (included in #Miscellaneous stress above).

Formerly the BrE–AmE distinction for adjectives carried over to corresponding adverbs ending -arily, -erily or -orily. However, nowadays most BrE speakers adopt the AmE practice of shifting the stress to the antepenultimate syllable: militarily is thus generally /ˌmɪlɨˈtɛrɨli/ rather than /ˈmɪlɨtrɨli/, although necessarily is in BrE often /ˈnɛsəsᵊrɪli/.^[45]

-ile

Words ending in unstressed -ile derived from Latin adjectives ending -ilis are mostly pronounced with a full vowel in BrE /aɪl/ but a reduced vowel or syllabic L in AmE /ˈˈəˈˈl/ (e.g. fertile rhymes with fur tile in BrE but with furtle in AmE).

AmE will (unlike BrE, except when indicated with^B2) have a reduced last vowel:^[1]

generally in docile,^{[nb 25]} facile, (in)fertile, fissile, fragile, missile, stabile (adjective), sterile, tensile, versatile, virile, volatile
usually in agile, decile, ductile,^[46] febrile,^{[nb 26]}^[47] futile, hostile,^[48] juvenile, (im)mobile (adjective & phone),^[49] nubile, projectile^B2,^[50] puerile, reptile, servile, tactile, utile;^[51]
sometimes in domicile^B2,^{[nb 27]}^[50] infantile, pensile, percentile, senile.^{[nb 28]} textile
never in crocodile, exile, gentile, reconcile; nor to compounds of monosyllables (e.g. turnstile from stile).

In some words the pronunciation /iːl/ also comes into play:

BrE /aɪl/, AmE /iːl/: camomile^A1, mercantile^A2, mobile/stabile, (decorations)^[52]

BrE /iːl/, AmE /ɪl/ or /ˈˈəˈˈl/: imbecile.

BrE /ɪl/, AmE /iːl/: rutile (BrE, AmE also /aɪl/).^[53]

Related endings -ility, -ilize, -iliary are pronounced the same in AmE as BrE.

-ine^[54]^[8]

The suffix -ine, when unstressed, is pronounced sometimes /aɪn/ (e.g. feline), sometimes /iːn/ (e.g. morphine) and sometimes /ɪn/ (e.g. medicine). Some words have variable pronunciation within BrE, or within AmE, or between BrE and AmE. Generally, AmE is more likely to favour /iːn/ or /ɪn/, and BrE to favour /aɪn/.

BrE /aɪn/, AmE (1) /iːn/: carbine^A2, Florentine^A2, philistine^A2, pristine^B1, serpentine^A2.

BrE /aɪn/, AmE (1) /iːn/ (2) /ɪn/: adamantine^A3.

BrE /aɪn/, AmE /ɪn/: turbine^AB2.

BrE /aɪn/, AmE (1) /ɪn/ (2) /aɪn/ (3) /iːn/: crystalline, labyrinthine.^[55]

BrE (1) /iːn/, AmE (1) /aɪn/ (2) /ɪn/: iodine ^A3B23.

Weak forms

The titles Saint and Sir before a person's name have weak forms in BrE but not AmE: before vowels, [snt]^[56] and [sə].

Miscellaneous pronunciation differences

These tables list words pronounced differently but spelled the same. See also the table of words with different pronunciation reflected in the spelling.

Single differences

Words with multiple points of difference of pronunciation are in the table after this one. Accent-based differences are ignored. For example, Moscow is RP /ˈmɒskəʊ/ and GAm /ˈmɑːskaʊ/, but only the /oʊ/-/aʊ/ difference is highlighted here, since both the /ɒ/-/ɑː/ difference and the RP use of /əʊ/ rather than /oʊ/ are predictable from the accent. Also, tiara is listed with AmE /æ/; the marry–merry–Mary merger changes this vowel for many Americans. Some AmE types are listed as /ɒ/ where GAm merges to /ɑː/.

^A2 means that American speakers may use either pronunciation;^B2 means British speakers may use either pronunciation.
