We present a framework, CALL-SLT Lite, which can be used by people with only very basic software skills to create interactive multimodal speech-enabled CALL games suitable for beginner/low intermediate child language learners. The games are deployed over the web and can be accessed through a normal browser, and the framework is completely language-independent. As the name suggests, the framework grew out of an earlier platform, CALL-SLT, which enables construction of similar games but uses a more sophisticated architecture. We review the history of the project, describing the type of game we are aiming to build and our reasons for believing that they are useful, and then present CALL-SLT Lite and an initial evaluation comparing the performance of the two versions of the framework. The results suggest that the Lite framework, although much simpler, offers performance at least as good as that of the original system.
