Phoneme /ɔː/ in General American

In General American the IPA phonetic symbol /ɔː/ corresponds to the vowel sound in words like "thought" and "cloth", and also "north" and "force". Sometimes the triangular colon /ː/ is replaced by a normal colon, as in /ɔ:/. Most American dictionaries don't write the triangular colon at all: thought /θɔt/.

In a non-rhotic accent /ɔːr/ is pronounced [ɔː] unless it is followed by a vowel, i.e. when the spelling has an "r", it is normally silent unless it is followed by a vowel.

In General American the "r" in /ɔːr/ is always pronounced. Many people pronounce /ɔː/ and /ɔːr/ with different vowels (e.g. "sauce" as [sɔs] and "source" as [sors]); however since the difference is predictable there is no problem using the same symbol in both cases (e.g. /sɔːs/ and /sɔːrs/). Merriam-Webster's Learner's Dictionary (MWLD) uses /oɚ/ for "north" and /o/ for "foreign". "Sauce" and "source" are transcribed with different vowels: /ˈsɑːs/ and /ˈsoɚs/.

There are places in the United Kingdom where /ɔːr/ is pronounced [ɔːr], and places in North America where /r/ is silent.
