In this thesis, we present a speaker verification system on the world wide web. In order to execute a wave recorder on the web browser, we implement an ActiveX control which can record our voice. This wave recorder component need to provide an interface to communicate with browser, then the web browser can record speech and analyze them to get speech character, and send the speech character to the server for further processing. If the result is correct, redirect to the following page. We use the Hidden Markov Models to construct the speaker verification kernel. We model each word by nine states, and combine a silence state between words. According to the above model and running the algorithm of HMM iteratively, finally we will get the optimal speech characteristic model, Once the model has been built, it will be used to verify the speaker. If we apply a speaker verification mechanism to the web security, our web site will get more security guarantee.
