Hey there!

Is anyone know how to get a current user speech(utterance) file name in the VXML application?. In UniMRCP log I see json and wav files are writing in /opt/unimrcp/var/.

Here a captured log

Or any alternative way to get the utterance in VXML application. I try to use recordutterancetype property in VXML it also not work.

I'm using Voxeo Prophecy V 16.0

One place to start might be the umsgsr.xml configuration. It will allow you to set the base uri to something other than http://localhost (assuming your vxml client is not running on the same host as UniMRCP). You may also need to configure a web server on the UniMRCP host to serve up the audio file location. Then, if your vxml platform supports the record features, it will be able to fetch the audio referenced in the Waveform-Uri header. Vxml provides the audio via the name of your <record> element, or via application.lastresult$.recording if using the recordutterance property. For the URI itself, I don't believe that is available, at least in standard vxml.

While I actually do not have anything to add to a very comprehensive response provided by Doug, just wanted to thank everyone for taking the time and participating in the discussions.
