Hey CB, how about [gaɪv]? Seven, [aɪt], [noɪn], ten.

Hi Jackson,
vowel letters are A, E, I, O, U.
Vowel sounds are all those sounds you use while speaking that are not consonants. The most common vowel sound in English is the schwa (IPA symbol: /ə/). IPA is the phonetic alphabet often used in phonetic transcriptions in dictionaries.
So, for example, BEAT is written with two vowel letters, but it's pronounced with one vowel sound (IPA symbol: /i/). And SO is written with one vowel letter, but it's pronounced with a diphthong, which is a vowel that sounds like two different sounds joined together (IPA for "so": /soʊ/).
But remember that not everyone speaks the same way, so there are people who use different sets of vowel sounds, diphthongs, etc.
