[Freeswitch-users] Speech recognition SpeechTools.jm Error

Wed Jan 11 10:48:02 MSK 2017

Sigh...

Need to confirm if this SpeechRecognition.jm script needs to be migrated to
XML handling based on this note:

"The new V8 module relies on XML support built into FS, since Google V8
doesn't have this built-in like Spidermonkey."
https://freeswitch.org/confluence/display/FREESWITCH/JavaScript+example+-+XML
http://stackoverflow.com/questions/38846047/freeswitch-speech-recognition-speechtools-jm-error?rq=1

Seems to be that handling XML

<result grammar="pizza_order">
  <interpretation grammar="pizza_order" confidence="100">
    <input mode="speech">pickup</input>
  </interpretation>
</result>

Require use of XML - use('XML'); as is not parsed by default, and original
.jm file may not work just using the original code.

Thanks
