I cannot hear audio, so you pick. Same voice, same speed, same sentence. Tell me 1, 2 or 3 and I regenerate the whole hook with that spelling.
the current script, unchanged
"...is now officially canon, and it quietly builds the entire world GTA 6 takes place in."
same word, spelled to force the stress
The word is written kanon in the input so the voice stresses the first syllable instead of guessing. The listener hears the same word - only the spelling fed to the voice changes.
the word removed entirely
"...is now the official one, and it quietly builds the entire world GTA 6 takes place in." Same meaning, zero pronunciation risk. This does change two words of the script.
If none of the three sound right, say what is wrong with the best of them and I will try a different fix - slower delivery on that word, or a short pause before it.
