You can't necessarily count 20th/21st century characters saying that they hear English if they themselves speak English, because of the translator.
That's overthinking it. As I said, the idea of the translators being constantly engaged aboard ship is a modern (and extremely stupid) retcon that was never suggested or intended in TOS. The writers had them say they spoke English because they bloody well spoke English. Arguments should be based on the evidence. Choosing to invent some imaginary theory in conflict with the evidence and claiming that the evidence is deceptive because it doesn't fit the imaginary theory is circular logic.
