ɑ

lot /lɑt/

In General American IPA phonetic symbol /ɑː/ corresponds to the vowel sound in words like "start", "art", "palm", "spa", "lot" and "stop".

In Received Pronunciation, the IPA phoneme /ɑː/ corresponds to the vowel sound in words like "start", "art", "bath", "ask", "palm" and "spa".

In most of North America the father-bother merger is in effect.[1] This means that IPA phoneme /ɒ/ sounds exactly like /ɑː/. This is the reason why "lot" and "stop" are mentioned in the first paragraph. Since many of the words with the phoneme /ɑː/ are spelled with the letter ‘o’, this phoneme is sometimes informally called “short o”. Moreover in Teflpedia (and also in dictionary.com) /ɒ/ means /ɒ,BrE ɑːAmE/.

Many people pronounce /ɑː/ and /ɑːr/ with different vowels (e.g. lodge as [lɑdʒ] and large as [lɑːrdʒ]); however since the difference is predictable there is no problem using the same symbol in both cases (e.g. /lɑːdʒ/ and /lɑːrdʒ/).

Cot - caught merger[edit]

Main article: Cot-caught merger

In many parts of North America (about half the United States and nearly all of Canada)[2] /ɑː/ and /ɔː/ sound the same. This is in addition to the father - bother merger, where /ɑː/ and /ɒ/ sound the same. This means that caught /ɔː/, cot /ɒ/, father /ɑː/ and bother /ɒ/ have all the same stressed vowel /ɑː/. In this accent /ɔː/ appears only followed by /r/ and the pronunciation is normally [oɚ] or [o], north is [noɚrθ] or [norθ] and glori is [gloriː].

Anticipated pronunciation difficulties depending on L1[edit]

Spanish[edit]

In Latin America American English is taught (the United Kingdom is far away). Spanish speakers tend to pronounce /ɑː/ according to the spelling. They will pronounce "palm" as [pam] and "lot" as *[lot].
