Cloud-recording based intelligent feedback system of voice information

Abstract

In recent years, opinion mining becomes a novel and multiuse research topic. This technique has wide and many real-world applications, such as e-commerce, business-intelligence, information monitoring, public-opinion poll, e-learning, newspaper and publication compilation, business management, etc.[1] The goal we develop the Cloud-recording system is to extract information from people's communication through telephones which may be forgotten by accident. Recently, the system can be applied to automate the telephone survey while telephone surveys now are mainly done by humans. With the Cloud-recording system, companies or governments and do the surveys automatically which means telephone surveys can be at a greater amount and a lower cost. In the system, DSR is used to extract features of phones and we translate the phones to text with the help of SPHINX. © 2012 Springer-Verlag.
