A SIP-Based Voice-Mail System with Voice Recognition

摘要

In this paper we propose a new voice mail service incorporating voice recognition, a function not realized in existing unified messaging systems. The proposed service, which we have also implemented and evaluated, is characterized by a voice-to-text conversion function with delivery of text and associated voice message by email. A Web-based GUI (Graphical User Interface) provides easy user access to voice messages. Telephone calls to the service are VoIP (Voice over IP) using SIP (Session Initiation Protocol) call signaling.
