In spoken dialogue systems, the most simple user-side error collection method is a "go back" input that is equivalent to "undo" button of ordinary graphical user interface. However, hard cording of "go back" destination is effective only in a strictly hierarchical menu-based dialogue system without shortcut. Such "go back" implementation causes a lost state problem in browsing around type of dialogue or frame-based dialogue. In order to deal with such a problem in VoiceXML-based dialogue systems, we explore and compare three solutions which have different pros and cons.
