This paper describes a novel way to implement a speech dialogue system. This system can accept new inputs while simultaneously analyzing the previous utterance. Two ticket reservation speech dialogue systems were built; one of them was based on the above method, and the other was based on accepting new inputs after analyzing the previous utterance. It was found that the new method improved the total average utterance accuracy by 5.4% and the total time spent to solve tasks by 4.7%. This shows that the new method is promising for increasing the interactiveness for the speech dialogue system, and, as a result, for making the system more user-friendly.
