Phonetic Rules of the ɑ: sound
In Received Pronunciation (RP), which is also known as BBC English or the Queens English, the ɑ: sound, also known as the 'long' /a/ or 'broad' /a/ sound, is used in a variety of words.
Rules:
- It often appears in words that have a single 'a' that's followed by consonants. Examples include "father" and "palm".
- This sound can also be used when the 'a' is followed by 'r' in words like "start" and "park".
- However, not all 'a's followed by a consonant would use the ɑ: sound. For example, 'a' followed by 'n', 'm', 'l', 'g', 'v', and 'b' typically would not use the ɑ: sound.
- Similarly, 'a' followed by a 'w' (as in "swan") or by a 'u' as in "launch" also tends to use the ɑ: sound.
- This ɑ: sound often isn't present in dialects of English from the north of England, where words like "bath" and "dance" use the short 'a' as in "cat", which is represented by /æ/ in the International Phonetic Alphabet (IPA).
Please note that English is a highly variable language, and pronunciation can change based on regional accents, individual speaker variation, and other factors. The rules above are general tendencies and might not apply to every speaker or every
