A spoken dialog interface of a mobile office robot is described. To realize robust speech recognition in noisy office environments, a microphone array system and a technique of switching multiple speech recognition proc-esses with different dictionaries are introduced. To real-ize flexible and natural dialog, task dependent semantic frames and keeping track of attentional state of dialog are used. The system is implemented on a real mobile robot and evaluated with sample dialogs.
