Integrating Speech Enabled Services in a web-based e-Learning Environment

摘要

We investigate the deployment possibilities of speech enabled services in a web based e-Learning environment. The integration of speech technology is realized with a client/server architecture. Therefore, the services speech synthesis, speech recognition, and speaker verification are installed at a central SpeechServer. The client uses a Java applet (Speech Applet), which is integrated in an HTML page. It takes the user's input (e.g. speech or text input) and activates the according service at the SpeechServer. The SpeechApplet is easy to integrate into existing web pages and aims at a simple JavaScript interface for communication between the web page and the applet. In this paper we introduce this system, explain different modules, and discuss first evaluation results of these technologies.
