The confidence score range for MRCP is not the same as the range for VXML2




Problem


MRCP returns a confidence score in the range 0 - 100 whereas VXML2 expects a score in the range 0 - 1.

Resolving the problem


A new parameter has been added for use in /var/dirTalk/DTBE/dtj.ini:

wvr.use.vxml2.confidencerange


This controls whether, in a system using MRCP, the confidence scores are returned to the VXML2 application in the range 0 - 100 or 0 - 1.

To use the range 0 - 1 set the parameter to true:
wvr.use.vxml2.confidencerange=true

To use the range 0 - 100 set the parameter to false:
wvr.use.vxml2.confidencerange=false

The default value for the parameter is false.
