Words spelled the same way they are pronounced

Is there a term for words that are spelled the same way they are pronounced? If so, is there a list of them somewhere?

For example, I have thought of:

• "a" spelled A pronounced "A"

• "I" spelled I pronounced "I"

• "ok" spelled O-K pronounced "O"-"K"

• "Io" (Jupiter’s moon) spelled I-O pronounced "I"-"O"

More explicitly, words whose spelling is pronounced the same as how the word itself is pronounced.
