element is used when a VoiceXML application
expects to receive voice
input, but the caller has neither spoken nor entered anything via the keypad. In syntactic coding, the noinput element abbreviates <catch
event= “noinput”>. There are several attributes contained in the <noinput> element. The count allows the application to handle different occurrences of the same event differently. Each <form
>, and form item
maintains a counter for each event that occurs while it is being visited; these counters are reset each time the <menu> or form item’s <form> is re-entered. The form-level counters are used in the selection of an event handler
for events thrown in a form-level <filled>. Counters are incremented against the full event name and every prefix matching event name. The cond attribute is an expression that must evaluate to true after conversion to Boolean in order for the event to be caught.
