摘要

本文旨在提供一个基于Asterisk PBX服务器的语音对话查询系统的理论和实现细节。Asterisk PBX服务器可以通过安装特殊的硬件PCI卡连接到传统的模拟电话或PSTN(公共交换电话网)中继线路,也可以通过使用各种VOIP协议(如SIP, IAX和H.323)连接到VOIP电话。这个查询系统是为印度铁路查询(印地语)以及英语设计的。本文介绍了如何在Asterisk服务器上部署模拟电话和软电话作为客户端接口的查询系统,并分析了查询系统的识别精度。

Speech based dialog query system over asterisk PBX server
This paper is intended to provide an insight into the theoretical and implementation details of a speech based Dialog query system over Asterisk PBX server. Asterisk PBX server can be connected to traditional analogue telephones or PSTN (Public Switched Telephone Network) trunk lines by fitting with special hardware PCI cards and to the VOIP telephony by using various VOIP protocols like SIP, IAX and H.323. This query system is designed for Railway Enquiry in Indian (Hindi) as well as English language. This paper describes how a query system can be deployed over Asterisk server for both analogue telephones and softphones as client interfaces and the recognition accuracy results are analyzed.
