Navigating in a Virtual Environment with traditional input devices such as mouse, joysticks and keyboards provide limited maneuverability and is also time consuming. While working in a virtual environment, changing parameters to obtain the desired visualization requires time to achieve by manually entering parameter values in an algorithm to test outcomes. The following thesis presents an alternate user interface to reduce user efforts, while navigating within the Virtual Environment. The user interface is an Android application which is designed to accommodate spoken commands. This Speech Enabled User Interface termed as the Speech Navigation Application (SNA), provides the user with an option to voice out the commands which they wish to see enacted/reciprocated in a virtual environment. The user can change the parameters to meet their needs. The idea behind this project was to minimize the effort needed to change parameters of any visualization, so as to obtain the desired view as per the requirement. This paper explains in detail the design, implementation and evaluation of the working project. This system is analyzed by simulating the working prototype in the DIVE.
