TLDR
It is concluded that empirical studies of the unique qualities of man-machine interaction as distinct from general human discourse are required for the development of user-friendly interactive systems.Abstract:
Current approaches to the development of natural language dialogue systems are discussed, and it is claimed that they do not sufficiently consider the unique qualities of man-machine interaction as distinct from general human discourse. It is concluded that empirical studies of this unique communication situation are required for the development of user-friendly interactive systems. One way of achieving this is through the use of so-called Wizard of Oz studies. The focus of the work described in the paper is on the practical execution of the studies and the methodological conclusions drawn on the basis of the authors' experience. While the focus is on natural language interfaces, the methods used and the conclusions drawn from the results obtained are of relevance also to other kinds of intelligent interfaces.read more

Phonetic accommodation in interaction with a virtual language learning tutor: A Wizard-of-Oz study
TL;DR: It is concluded that phonetic accommodation on the level of local prosody and segmental pronunciation occurs in users of spoken dialog systems, which could be exploited in the context of computer-assisted language learning.

The development of communication skills: modifications in the speech of young children as a function of listener
Marilyn Shatz,Rochel Gelman +1 more
TL;DR: This paper found that the 4-year-old adjusted his speech with regard to the changing capacities of different-aged listeners, and the younger the 2-year old, the greater was the observed speech adjustment.

Cross-linguistic differences in parsing: Restrictions on the use of the Late Closure strategy in Spanish ☆
Fernando Cuetos,Don C. Mitchell +1 more
TL;DR: The results throw doubt on the suggestion that the Late Closure strategy is favoured (in English) mainly because it is efficient in information processing terms and suggest that different languages make use of parsing strategies in an essentially arbitrary way.
