Developing an interactive telephone application using VoiceXML


Welcome!

This is a tutorial for developing an interactive telephony application using Voicent Gateway, a VoiceXML gateway that is fully functional on a PC with a simple voice modem. It should be easy to apply the source code to any VoiceXML-based system. You can download a free Voicent VoiceXML Gateway at Voicent Website.

The system will answer an incoming call announcing the service name, asking the caller to say the name or press a key to select the time zone, and then reading back the current time of that time zone.

Though simple, this tutorial contains all the basic components of an interactive telephone application:

  • Playing audio prompt for general information or ask a question
  • Recognize user input, voice or DTMF tone
  • Dynnamically generate content for interaction

Using a VoiceXML gateway server as your development platform, you can save a lot of time on your product development. Instead of dealing with telephony specific problems, you can focus on creating value added features for your customers. The following products are all based on Voicent VoiceXML Gateway.
