In VoiceXML applications, you can declare a form or field to be private using the following property statement:
<property name="private" value="true"/>
While a private form or field is executing, Experience Portal does not write any speech recognition results, DTMF results, or TTS strings into the session transcription logs or into any alarms that may be generated during execution. Once the private form or field has finished executing, Experience Portal resumes logging these items as normal.
Note:
If tracing is turned on for the MPP, Experience Portal ignores the privacy property and writes the requested debugging information into the MPP trace logs.
