I have solved my problem with the help of a suggestion from a different source.
I had to do it more precisely than had been suggested.
To add the correct spelling of a name to the voice recognition that comes with the built in keyboard, not Siri, that hasn’t accepted the spelling you have wanted in the past, do the following:
Go to:
Settings
General
Keyboard
Text replacement
Press the + in the top right corner,
•• ONLY FILL IN THE TOP FIELD. It’s titled: “Phrase”.
Type the spelling of the name you want it to recognize.
Press: Save (It’s in the upper right corner).
(DO NOT FILL IN the field named: “Shortcut”).
The phone will fill in the second field: “Shortcut” for you with the same spelling you entered under “Phrase”.
The spelling you want will now be recognized.
