Interactive Voice Response System Based On Speech Application Language Tags--The Implementation Of Phone Service And Prompt Database

SALT(Speech Application Language Tags) is a markup language that is able to offer new method aimed to solve the interactive problem between user and electric equipment and independent of platform, it is used for creating the newly application system that is cutover through speech platform. IVR system is Interactive Voice Response system, it can not only provide voice and fax services, but also deal with voice processing, fax sending or receiving, and the relative explanation and operation of business flow.According to the characteristic of SALT technique, this paper is considered to apply the SALT in the development of the call center of IVR system, we design the Contacts system, the function of this system has expanded further, and so it can provide more quick and more natural interactive service style. We lead SALT technique into this system, that is lead speech interface into it, and it can make function more satisfactory, and I accomplish the Phone Service function Model Block, Prompt database and the expansibility of this system.This article include six chapters, the first chapter simply introduce the research contents of this subject; the second chapter introduce the technical knowledge related to this design (IVR system, voice signal processing technique and SALTtechnique); the third chapter introduce the prepotence of IVR system based on SALT ; the fourth chapter introduce the gross design of IVR system based on SALT and Model block divided; the fifth chapter introduce the implementation of Phone Service function Model Block and the expansibility of this system in details, this function Model Block offer communication service to user, and the key function of it is to confirm the contact name and his telephone, and then call him, the expansibility can let the system to renew contact database timely; the sixth chapter introduce Prompt database.Through establishing a IVR system based on SALT (small-sized query call center), this paper has made a deep research on IVR, SALT, voice technique and their comprehensive application. With using the newly SALT technique, the system is ensured that it has wide application foreground with the characteristic of advancement, open, friendliness, stability and reliability etc.
