| Research Abstract |
In this research we study how dialog rhythm influences user's comfort and reliability and propose a new framework for building spoken interfaces based on this framework. Although we confirmed user's increased satisfaction and smoothness of conversation, we have not reached the level of naturalness of human to human dialog.
To achieve this we have improved our model for generating rhythmical dialogs, re-implemented it into the system and increased processing speed.
In result, we achieved better human-likeness and reliability comparing to the previous system, but we could not reach evaluation similar to human's as our system's timing recognition performance level, voice recognition and language understanding performance levels were imperfect.
