How do you synthetically alter the frequencies of letters?

I'd assume just replace words with synonyms containing the appropriately weighted letter/s?

The hard part is going to be keeping the flow of the text, whilst brute forcing a thesaurus into it!

The easiest is again to do synonym/word/punctuation replacement but with the intent of altering the letter frequency instead of embedding information directly.

It's effectively a compression scheme built on-top of synonym replacement using "extra" available information to pack more bits in less words. This means even sentence long quotes in summary form are enough to compromise someone.

It sounds to me that it would be blatantly obvious that a human didn't write whatever result that may produce.

And I don't quite get how you can encode that much information in a sentence without it being completely garbled.

It seems to me that it'd be very obvious that a human did not write whatever result that could produce.

Here's 5 bits in that simple sentence. I'm sure others can do better.

It now occurs to me: inject common proofreading mistakes that often go unnoticed.

It does seem tough to vary word usage to produce the right frequency of letters while keeping the meaning and not having it read awkwardly.
