MICROSOFT IRINA DESCKTOP voice assistant, how to add or edit dictionaries?

Question

Windows

Friends, the question is serious, how can you edit the voice assistant in windows 10, because Irina has few words, some of the accents are incorrect, apparently from the lack of dictionaries. For reading text books, it would be quite suitable, but a very small dictionary.
Surfed all over the internet.
An example of a drunken Irina, this is not a fake there, it happens when the speech slows down.
