English vowels glide — 'no' is really 'no-u'. Italian vowels are pure: a, e, i, o, u each keep one clean sound from start to finish. This single habit — cutting the glide — is the fastest accent upgrade available.
Ciao, come stai? — Sto bene, grazie!
Every vowel crisp: cha-o, ko-me, sta-i.
Practice with music: Italian songs stretch vowels beautifully. Sing along to any classic — Volare works — and let the long notes teach your mouth the pure sounds.
