When I text my husband something like "I picked up Hailey from school and am on my way," Siri always misspells my daughter's name as Haley (with no "i"). I have an entry in my contact info identifying who my daughter is, but when I'm dictating a text or other message, that appears to be irrelevant.
I'd like to teach Siri that any time I refer to my child's name it should always be spelled a certain way. I feel foolish sending messages with my own child's name misspelled.
