Siri won't spell my daughter's name correctly.

My daughter's name is Kara (Care-ah) but Siri spells it Cara. SOMETIMES if I say (Car-ah) then I get her to spell it right, but I rarely remember to "mispronounce" my daughter's name. I made a contact for her, put Cara as the phonetics, told Siri that Kara is my daughter & when I ask who my daughter is Siri gets it right. But when I say Kara how I want, it still comes out Cara in the text. I also tried putting Kara as the nickname for her contact, making a shortcut to turn Cara into Kara, and there are no other Cara's in my phone. I've also restarted my phone after doing all of this. None of this has helped Siri spell my daughter's name right when I voice text.

Any ideas?

Thanks!
