You're not writing a letter, you're dictating it.
Wait... You're trying to say the scribe is going to faithfully record all the noble's mispronunciations, grammatical errors, contractions, foibles of speech, and regional dialects faithfully in a phonetic transcription of
sounds instead of actually writing the words that the noble is saying, and do it in a manner that makes the noble sound like some 6 year old, backwoods, uneducated,
retarded "differently-abled" kid with a speech impediment? Regardless of who writes it,
it's a letter.
