I am Vietnamese & If I see "Le" & "Bo" I will pronounce them as
But seem English doesn't have any
/o/ as a phoneme. A phoneme /ˈfoʊniːm/ is one of the units of sound that distinguish one word from another in a particular language. The difference in meaning between the English words kill and kiss is a result of the exchange of the phoneme /l/ for the phoneme /s/. Two words that differ in meaning through a contrast of a single phoneme form a minimal pair. (Wiki)
See this Vowel chart picture (Source)
See the vowel "
o" I couldn't find any word in English dictionary that has vowel "o" stands alone without any other vowel standing next to it.
Let say, I can see
/ɡoʊ/ (go), the
/ʊ/ stands right after
There are no words that can pronounced as
/ko/ where the
/o/ stands alone.
The chart doesn't have
/eɪ/ is popular in English.
To sum up, I think we don't have
/o/ as a phoneme in English but diphthong
So, I think the Native English speakers will say
/boʊ/ when seeing 2 Vietnamese words "Le" & "Bo".
If they speak like Vietnamese, they should say
/bɔ/ but most of time I think they will say
In standard IPA vowel chart (audio version), they tend to pronounce
/oʊ/, although not 100% sound like
/oʊ/ but 80% sound like
/oʊ/ (see IPA audio chart).
Am I right?
