Question: what are long vowel sounds?
Answer: 'Long vowel' is the term used to refer to vowel sounds whose pronunciation is the same as its letter name. The five vowels of the English spelling system ('a', 'e,' 'i,' 'o,' and 'u') each have a corresponding long vowel sound /eɪ/, /i/, /ɑɪ/, /oʊ/, /yu/.
