The design and development of user interfaces for voice application in mobile devices

Voice can be a powerful tool for use in human computer interaction because it is the fundamental means of human communication. With the rapid growth of wireless communications, the need for voice recognition techniques has increased greatly. Portability and wearability, which are necessary items for being computationally powerful mobile devices, will be reinforced by attaching voice applications, since voice can support invisible communication with a mobile device as a natural way of communicating. Voice applications based on voice interfaces, voice recognition, and voice dialogue management can help users to be focused on their current work without extra effort for hands or eyes, and without extra learning time. In this paper, we present the general requirements and design for a proposed software framework and architecture of efficient voice-based applications on a mobile device, and also we offer a prototype application that has the ability to interact with a user by voice commands. In addition, we present usability testing for the application in order to find usability problems by suggesting evaluation processes, and then we discuss further progress to improve the application on mobile devices.
