Each VoiceXML field can contain a prompt, code to handle the user inputs and errors, and a grammar.
Grammars define the range of input values the user can provide.
Once all fields have been filled, the form is submitted to another VoiceXML document or to a script on a Web server via the HTTP protocol. There are two ways users can provide input to form fields. The second is through voice commands, which will be covered in Part II of the VoiceXML series. One common task is to ask a user to input their PIN code to identify who they are. Good Morning Mr. Eisenzopf.
