Moreover, VoiceScape applies speaker verification for restricting the access to proprietary data and private areas of the Internet as well as to the Internet in general. Speaker verification is an efficient and powerful biometrical method for identifying a person. The further development of VoiceScape is directed to the design of a JAVA based Client-Server concept presuming that a standard for speech input will be set. During the entering of VoiceScape the identity of a user is checked in a speech dialogue. Utterances from the user are compared with those recorded during the enrollment procedure.
Speaker verification is very efficient and flexible.
A high security can be realized for private data areas and applications, e.g. eMail, Telebanking etc., while a relatively low security level is sufficient for the general Internet access. Voice commands from a permitted user are recognized via the internal speech recognizer of VoiceScape. The commands are interpreted and the corresponding actions are initialized. The vocabulary of the speech recognizer is adapted automatically to the contents of an actual HTML-document. The hyperlinks are phonetically transcribed and registered as new voice commands in the vocabulary.
