A prototype system to assist call routing task for telephone operators is reported in this paper. The system was developed based on a company organization profile with description of its divisions instead of a corpus of recorded and transcribed call-routing dialogs. An acoustic module and an information retrieval module were built specifically for this task. By integrating acoustic and information retrieval module, we have built a system with a satisfactory performance and provide a promising approach to call routing. Simulation results indicate that the proposed algorithm can improve call routing performance over baseline classification methods. A working system based on the proposed approach has been implemented and experimental results are presented.
