In simpler terms, the VOSAC is an app that can play the role of a customer support agent or person.
More generally though, the VOSAC is a generic, parametric, user-configurable, voice-operated support assistant robot applicable to as many scenarios or problems in the form of information access or retrieval, as part of user support, artificial assistants and the like.
SO HOW COULD IT HELP YOU?
Give VOSAC access to one or more knowledge bases (in the form of VOSA-compatible QAKBs), and VOSAC, which is the Voice Operated Support Assistant Client, can intercept your voice questions, and offer back meaningful, useful answers. It also helps in manually browsing such digitized QAKBs - Question-Answer Knowledge Bases, where one would traditionally browse a FAQ on a website or a physical user manual.
