Are you sure you aren't French Québeker?

Manybe in another life. The first time I heard somebody trying to do a francophone Quebecker was Olivier in The 42nd Parallel. (Lord Larry also later did one of the worse American accents I've ever heard a British actor do as General Douglas MacArthur in Inchon.)

The diphthong in standard English in the word wine is /aɪ/ (see the IPA chart for sounds of various brands of English, link). The vowel in (standard) French vin is an /ɛ/ (link).

Ceci n'est pas un seing.
