Developing a Spoken Dialogue System Using the CSLU Toolkit
RAD (Rapid Application Developer) is a graphically based authoring environment for designing and implementing spoken dialogue systems. RAD supports directed dialogues using a finite state-based dialogue model. The developer selects various dialogue objects and links them together to make a dialogue graph. These objects perform functions such as speaking a prompt, recognising the user’s input, and executing actions related to the dialogue. RAD also includes animated characters and facilities for presenting media objects such as pictures and sounds. Once the dialogue graph has been constructed, it can be tested using speech input and output.
