Music to my ears

Do the notes of english vowels match any scale? Yes, but apparently all latin languages use the same Formants, so the hunt continues. I believed the main cause of accents is the inability to play the "vowel scale" of a language. For example there is no "eu" sound in English hence the missing note when French is spoken by anglophones. So keep looking.

This table lists vowels and approximate matches on a piano, I want to compare them sometime:
