“The Vietnamese word “phở” is properly pronounced with a falling-rising tone, as if asking a question. Its final vowel is not a long “o,” but instead rhymes, at least to Anglophone ears, with the “u” in the English word “but”. A more accurate way to produce this sound is to make an English /o/ sound but not round the lips. The “ph” is pronounced as an “f.” The resulting pronunciation sounds like ‘fuh?’.”
