In Received Pronunciation; I personally pronounce it /ai/. Two years ago, I drew a character for the English diphthong /eɪ/ (see at https://scratch.mit.edu/projects/860692750/) and @EliteForce24 asked if I would do /aɪ/. It never really crossed my mind until yesterday, when I drew him as an ice climber, wearing a puffy jacket, boots, gloves, and a ski cap.
