IPA phoneme /ɔɪ/
In English, both in Received Pronunciation and in General American, the IPA phonetic symbol /ɔɪ/ corresponds to the vowel sound in words like "toy" and "coin". The spelling of this sound is very straightforward: normally "oy" at the end of the syllable and "oi" in other positions. In the words in this page the only exceptions are proper nouns (Joyce, Floyd, Lloyd and Freudian).
In strict IPA diphthongs need an inverted breve under their less prominent vowel: /ɔɪ̯/. However the notation we are using does not have the symbol /ɔ/ by itself (it has /ɔː/), and therefore we know that the sequence /ɔɪ/ has an implied inverted breve below /ɪ/.
Some common words which practice the pronunciation of /ɔɪ/ include the following:
- with "oi": appoint - avoid - choice - coin - Illinois /ˌɪləˈnɔɪ/ - join - joint - noise - oil - point - soil - spoil - voice
- Exceptions: "oi" as /əʊɪ/: coincide - going
- with "oy": boy - destroy - destroyer - employ - employee - employer - enjoy - Floyd - joy - Joyce - Lloyd - royal - toy
There is a tendency in English to move to the previous syllable a /j/ sound that is at the beginning of a syllable. Then /V.jV/ becomes /Vɪ.V/. For example "lawyer" has a common pronunciation of /ˈlɔ:jər/ but it can also be pronounced /ˈlɔɪər/. Similarly for "sawyer": /ˈsɔ:jər/ or (less frequently) /ˈsɔɪər/.
Less common words
- with "oi": android - boil - foil - moisture - ointment - poison - sirloin - toilet
- with "oy": annoy - boycott - oyster - royal - soy
- Other: Freudian
