I want to learn voiceXML and now i want to what is GRXML. I understand that GR stands for grammer but why it is used in VoiceXML. What is SSML and CCML....Why they are used in VoiceXML. To be precise i want to know how VoiceXML works and how the above mentioned jargons are used. I found some websites they are too hard to understand at this level. Your help is very much appreciated.
Thanks in advance,
