Efficient Voice User Interface System Using VoiceXML and ASP.NET 2.0

The web-based application by VoiceXML service on the Internet is gradually being accepted for the human-machine interaction because it provides the speech-enabled function and makes telephone access a reality. Many companies are interested in building the effective dynamic Voice User Interface (VUI) system into the architecture of the already existing web application. The previous papers [1, 2] suggest that they demonstrate how to design and implement using VoiceXML and Active Server Pages. However, they have used only one server script language, so it is not efficient. For that reason, we have built another design that is more efficient for VoiceXML. Experimental results demonstrate that ASP.NET 2.0 shows the highest communication success rate and the lowest response time for web surfing.
