If you add your name into the prompt that adds context for the LLM-check, it will from context use "Simi" and "see me" correctly. Feel free to try :)
This is the same mechanism that changes "Tom" to "Thom" in the Tears of Steel demo (turn off elevenlabs for that run because it magically knows when it's transcribing ToS ;)
It will probably even be able to correctly pick it up in a longer text purely from context, though it might still miss-spell your name because it has no way to know the actual spelling. Same would be true for a human subtitler btw :)
