The form interpretation algorithm (FIA) drives the interaction between the user and a VoiceXML form or menu. A menu can be viewed as a form containing a single field whose grammar and whose

The FIA must handle:
The main loop of the FIA has three phases:
<filled>elements to perform actions such as input validation. An event is processed by executing the appropriate event handler for that event type.
Note that the FIA may be given an input (a set of grammar slot/slot value pairs) that was collected while the user was in a different form's FIA. In this case the first iteration of the main loop skips the select and collect phases, and goes right to the process phase with that input. Also note that if an error occurs in the select or collect phase that causes an event to be generated, the event is thrown and the FIA moves directly into the process phase.
