一种轻量级电话语音流程定义语言TVPDL设计与实现

Design and Implementation of a Lightweight Telephone Voice Process Definition Language

在电话语音系统的使用中,一旦语音业务流程发生变化,通常需要修改相关应用程序代码。轻量级电话语音流程定义语言TVPDL可以将任意类型的电话语音流程以脚本的形式进行定义。通过在应用系统中内置电话语音引擎,对电话语音流程脚本进行解析并执行。当未来需求变化时只需要更改流程定义即可,而不需对应用系统本身做任何改动。采用TVPDL定义流程的方式,大大增强了电话语音系统的灵活性。

This paper proposed a lightweight telephone voice process definition language （TVPDL）, which supports the definition of all kinds of telephone voice processes. The processes are parsed and run by telephone voice engine. If the business process needs to be changed in future, we can only adjust voice process definition and need not to change the application. In this way, the flexibility of telephone voice application has been improved greatly.
