Hey Siri on iPhone Chooses Wrong Contact Every Time

Hey Siri on iPhone Chooses Wrong Contact Every Time when faced with contacts having similar first name.

No matter how many times I say, "Hey Siri, call Melani", it picks the wrong contact.

I have told it that my "Melani" (First Name/Last Name) is my spouse. I did the prescribed action of saying, "Hey Siri, (Contact First Name/Last Name) is my wife", which Siri then verified.

I have added Melani as her nickname. I have even added the field to Contacts, Preferred pronunciation, of "Melanie" for her first name of Melani.

I have gone to the Shortcuts app and added a shortcut that every time I say, "Hey Siri, text Melani" it will send a text message to the correct contact for my spouse.

I have repeatedly said, "Hey Siri, text Melani" and then cancelled when Siri repeatedly selects the incorrect contact, in the hopes that there was some sort of diagnostic built into the Siri system which recognizes when non-favorable actions are repeated (signified by cancelling repeatedly), and the throws Siri into a learning mode to correctly select the correct contact.

I have turned off and then back on the different Siri settings, hoping to reset something.

I assumed that there was some sort of priority built into Siri for selecting correct contacts, such as frequency of contact history, or giving priority to contacts with closer relationships to the iPhone owner, or how recently a contact was interacted with.

None of that seems to be happening, since I interact with my spouse way more frequently, and all of the listed assumptions of priority above would normally apply to my spouse instead of the other contact which keeps repeatedly being selected.

If you've made it this far, possibly you have similar pain, or hopefully, have more esoteric solutions to the problem, rather than the basics I have covered so far?

Any higher-level knowledge or help would be much appreciated, as I would assume that I'm not the only one experiencing this.

Oh, by the way, this is not directly related to which iOS version I'm running. It has been a continuing ordeal for many revisions of iOS,
