The internal structure of the applications has been evolving in tandem with the programming paradigms and ways of interacting with the machine. At the beginning the programs interfaced with the user in textual form, commonly based on menus, that was the time of structured programming and applications with ’serial’ architecture. Later came the graphical interfaces, accompanied by a boom in programming object-oriented architecture. From the point of view of end users, this was a step forward in terms of ease of use, particularly for inexperienced people in the management of computing applications. The next step could be to incorporate the Natural Language interaction, the Voice. Again, this change should introduce a different way of thinking about applications so that you can enhance the positive impact of this mode of interaction. Therefore, following with the company vision, the goal of this project will be investigating about possible voice services for Handsfree Bluetooth devices. Starting from simple interfaces to some existing services, the project will continue with new ones, designed by the student, in the field of social networking, blogging, email, news, etc. The design will imply some programming skills with HTML, XML, VXML, PHP, Perl, etc and knowledge about voice servers architecture
