Example

<?xml version="1.0"?>
<vxml version="2.0">
  <property name="recordutterance" value="true"/>

          Please say your first name and spell it.
        </audio>
      </prompt>
      <filled>
        Your recording is <value expr="first_name$.recording"/>.
        The recording size is <value expr="first_name$.recordingsize"/> bytes.
        The recording duration is <value expr="first_name$.recordingduration"/> milliseconds.
      </filled> 
    </field>
  </form>
</vxml>

Explanation

From this example, the “recordutterance” attribute sets up three shadow variables: recording, recordingsize, and recordingduration. The recording shadow variable contains the last utterance if audio was collected. The recordingsize shadow variable contains the last utterance recording size in bytes. The recordingduration shadow variable contains the last utterance duration size in milliseconds.
