How can I correct Siri from misspelling names?

Has anyone figured out how to correct name spelling?

My daughter’s name is Aliyah and every time I use Siri to send out a text, I have to correct it from “Aaliyah”

Same with my sister, who’s name is Katharine, but it’s always spelt as “Catherine”

this is super frustrating when I looks like I don’t know how to spell my own family’s names
