Studies in Spirit Speaking is the objective of the quest Duke Nicholas Zverenhoff (quest).

Meaning
The "OoooOoOo OoOoOoO"s found in Studies in Spirit Speaking are a reference to Ultima Online. Dead players in UO could not communicate with living players; all they saw was "OooOoooOo"s. Players could study spirit speak to learn what they were saying, which then would reveal parts of the speech.
