About

Example speech recognition application in python. Many instructions and comments exist in the recipewizard.py script file itself.

Configuration

This tutorial assumes you have mod_python correctly installed. It also depends on mod_openmrcp to be installed and working with an automatic speech recognition server.

  • Open /usr/src/freeswitch/scripts/python/recipewizard.py and customize the GRAMMAR_ROOT variable and TTS settings to match your system.
  • Create $GRAMMAR_ROOT/mainmenu.xml from contents in mainmenu() comments.
  • Add scripts dir to your PYTHONPATH.
    export PYTHONPATH=$PYTHONPATH:/usr/src/freeswitch/scripts/python
  • Add an extension to the dialplan under test
RecipeWizard dialplan extension
<extension name="2001">
    <condition field="destination_number" expression="^2001$">
      <action application="python" data="recipewizard"/>
    </condition>
</extension>
  • Restart FreeSWITCH. 
  • Call the extension.
