Enabling Speech Based Access to Information Management Systems over Wireless Network

While wireless networks provide a greater autonomy to working people, interacting with a distant system is still constraining in terms of focus and abilities. Indeed, using a mobile terminal generally involves to look at it and use it manually. On another hand, last decade’s improvements in the field of speech processing techniques have allowed to realize voice enabled interfaces which represent a more natural way to interact for human operators and free their visual focus as their hands. Yet, low cost and low consuming mobile devices are not suitable for the implementation of complete speech processing algorithms which are often CPU and memory consuming. Moreover, inherent problems of wireless networking, such as connection loss, have to be taken into account in the design of a voice enabled interface. In this paper we propose an architecture of a mobile and distributed voice enabled interface for accessing to customer applications.
