document: A portable Auto Attendant System with sophisticated dialog structure An attendant system connects the caller to the party he/she wants to talk to . Traditional systems require the caller to know the full name of the party . If the caller forgets the name , the system fails to provide service for the caller . In this paper we propose a portable Auto Attendant System -LRB- AAS -RRB- with sophisticated dialog structure that gives a caller more flexibility while calling . The caller may interact with the system to request a phone number by providing just a work area , specialty , surname , or title , etc. . If the party is absent , the system may provide extra information such as where he went , when he will be back , and what he is doing . The system is built modularly , with components such as speech recognizer , language model , dialog manager and text-to-speech that can be replaced if necessary . By simply changing the personnel record database , the system can easily be ported to other companies . The sophisticated dialog manager applies many strategies to allow natural interaction between user and system . Functions such as fuzzy request , user repairing , and extra information query , which are not provided by other systems , are integrated into our system . Experimental results and comparisons to other systems show that our approach provides a more user friendly and natural interaction for auto attendant system
