Abstract
In this work we present a man-machine dialogue corpus acquired within the framework of the SpeakyAcutattile project with the Magic Technique of Oz. The corpus contains more than 60 hours of audio recording, inter-written, and video. It is dedicated in particular to the analysis of turn management and the resolution of errors. The system simulation with Oz's Magician was aimed at a voice dialogue without restrictions by the subject, both at the turn management level and at the phrase composition level.

Introduction
In this work we present a man-machine dialog corpus acquired within the framework of the Speaky Acutattile project, a digital platform for domestication designed for the support of weak outness (older, non-visible, etc.).In this case, it is necessary to ensure that you have the right to use this product in order to ensure that you have the right to use this product in order to ensure that you have the right to use this product. The platform has been designed to provide users with a simplified tool for managing the household equipment and other multimedia devices present at home (TV, stereo, etc.).But also for online access to many public services, such as health care, online payments, bookings, purchase of travel tickets, etc. For the data collection was used the Magic of Oz technique (Fraser and Gilbert, 1991; Dahlback et al., 1993). The technique, although requires more attention and resources than other speaker selection strategies, is commonly placed among the most reliable systems for user-oriented voice interfaces prototyping and data collection on how to interact with users. Excepting some structural vices related to the experimental context (such as the subject‚Äôs minor involvement compared to the real user), the relevance of a machine dialog corpus collected with this method is determined by the definition of certain parameters that a priori determine the behavior of the Mago, in fact making it by the user as possible assimilable to a machine (machine-like). In this work was also applied a mixed initiative system simulation model (Allen et al., 2001) with graphics √âframeand- slot√ì (Bobrow et al., 1977), including the dialog behavior protocol. The Magic Technique of Oz therefore allowed to elaborate the grammatics of understanding of dialogue with certain variants, while verifying the subjects‚Äô reactions to a system that appeared as real and did not force to interact pathways required for the resolution of tasks.

Conclusion
The Magic Technique of Oz allowed us to get a controlled corpus on some aspects of interaction that provide indications for the architecture of the dialogue system. The current data will be integrated with the acquisition of a new corpus in which the Oz Magician will be replaced by the prototype of the system, facing the same type of experimental user and the same use scenarios, in order to obtain data comparable to the current, both to improve the system performance, and to obtain valuable information on the Oz Magician technique. The database distribution policies will be defined at the end of the project (June 2015), and hopefully will be free for research activities, of course prior to NDA (Non Disclosure Agreement).
