Nowadays, computer games are involved in a child’s education as tools for learning or practicing some academic skills. However, most educational games are designed without any considerations about children with motor system difficulties. Thus, the main benefit of multimodal interfaces is to allow for inclusive design, which will enable children with motor disabilities to use the same applications other children use. Since focus and concentration are major skills for children in the learning process, many physical games can be performed with assist from parents or teachers to practice these skills. This project aims to explore the effectiveness and the use of multimodal applications as computer-based exercises by implementing a multimodal system that offers an inclusive design for three interactive games to practice the skill to focus. In this project, Say-it is implemented as a functional multimodal prototype to demonstrate the value of multimodal interfaces in the education of young children. It is designed to provide the advantages of both current physical games and computer exercises and make these exercises available for children with wide rang of abilities. Also, Say-it can be considered as an experimental prototype to explore the performance of using CMU Sphinx 4 framework as an underlying speech recognition tool for the application. The results of using Say-it show that multimodal games can be designed using the existing speech recognition technologies, such as CMU Sphinx 4 framework. Also, using different input modalities in the proposed prototype makes the games more enjoyable and challenging for children.
