To use the exorcism book in Ghost Hunters Corp, you will need to have a microphone and make sure it is working.
If your microphone is working, you will be able to use the book by reading lines precisely as they are written to exorcise the various types of ghosts you can encounter in the game.
To do this, you must first identify the entity you are facing by collecting evidence in the game. Once you have enough evidence, the game will recommend a passage for you to read to banish whatever ghost you are facing.
Read this passage as it is written on in the book, and you should be able to exorcise the ghost properly, but only if you are not interrupted. The spirit will not be exorcised if you get attacked or stop halfway through the exorcism passage.
If you have any problems with the game picking up your mic, you can always tweak and fiddle around with the settings via the options menu in the game. It's recommended to do this before heading into the game, so you don't mess up any missions or ghost hunts.
Along with exorcising ghosts, the exorcism books can also be used to annoy spirits early on in the game to get them to show themselves.
Using the book early can be good as it can reveal what ghost you are dealing with, but the spirit will become hostile, so it might be tricky to survive the encounter.
