An incremental system takes advantage of upcoming data as early as possible. In other words, an incremental system processes received data incrementally. Incremental systems can be useful over non-incremental systems to build spoken dialog systems when we are looking for faster and more human-like behavior. For example, human-to-human conversations are incremental, as a listener does not wait for a speaker to finish speaking to begin understanding. Inspired by the fact that Robot-Ready Spoken Dialog Systems must be incremental and need to work distributedly, and IU framework "breaks" in a distributed architecture, I attempted to use the IU network to fulfill the incremental requirements and be able to extend the IU framework to work flawlessly in a distributed environment. This work aims to answer the question whether we can make a distributed IU network efficiently and consistently. More specifically, I explored the optimal ways to establish a complex IU data store that can facilitate the conservation and accessibility of the total generated IU data network in a distributed environment avoiding the \breaking" of the IU network, and act as a backbone for a final and complete "Robot-Ready" incremental dialog system. We evaluated the HRI response differences happening along with IU store implementation differences in a live, interactive study with robots and found out that humans do notice small performance differences and subconsciously become judgmental of robots' anthropomorphism characteristics in relation to the robots' performance.
