The word "pronunciation"

With easy words, I try to tell you the word used before the last of my articles.

      noun: "pronunciation"
      verb:  "pronounce"

The two words are different between "nun" and "noun" to be confusing or misleading. I need other words because I can't memorize the spelling of the words yet.

Maybe, that's
        "letter sounds; sounds of a letter or several letters"
                                                          as vowels and consonants.

ex. make sounds of letters of a word out

I'd love the cards in the top photo from Canva.
Have they been being sold anywhere?
