I would assume
Elise.
I didn't even think
Alice until I opened the post.
I am not sure that an
Alice pronunciation would phonetically make sense due to the final 'e' in
Alise. The ending vowel gives the 'i' a long sound. You would have to spell it
Alis or Aliss to phonetically get
Alice following English rules.
Not that the English rules of pronunciation are always followed in names, of course.
