Throughout the years, SOVO has built significant intellectual property in the live captioning of TV broadcasts, parliamentary sessions, and other events. A great portion of this intellectual property takes form in a wide variety of language models and dictionaries, which model how words, sequence of words and sentences are used in the different live productions. The SOVO dictionaries, containing over half a million words associated with one or many pronunciations, are continuously updated and improved. SOVO has worked for a decade to build its dictionaries, containing tens of thousands of unique names of people, places, teams and other specific terms used in TV broadcasts, including all the names of athletes and teams for sports-related broadcasts, names and terms related to politics, public affairs and popular culture, weather and local geography terms, etc. The SOVO dictionaries (shared among all captioners, present and future) represent an invaluable asset.
