from the Plum Voice IVR Glossary
The <record> element is an input item that collects a recording from the user in a VoiceXML application. A reference to the recorded audio is stored in the input item variable, which can be played back (using the expr attribute on <audio>) or submitted to a server. The record property has 9 attributes. Name indicates what input item variable will hold the recording. Cond, is an expression that must evaluate to true after conversion to Boolean in order for the form item to be visited. Expr is the initial value of the form item variable. If exp is initialized to a value, the form item will not be visited unless the form item variable is cleared. Type indicates the media format of the resulting recording. Beep, if true, is a tone emitted just prior to recording. Maxtime specifies the maximum duration to record. Modual, if true indicates that all dtmf input will be stored. If false, all active dtmf grammars are turned on while recording. Finalsilence is the interval of silence that indicates end of speech. Dtmfterm when false, indicates that input is ignored, and when true, indicates that the input will immediately interrupt the recording.
